GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
59 Temple Place, Suite 330, Boston, MA 02111 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
Appendix: How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) 19yy <name of author>
|
||||
|
||||
This program is free software; you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License as published by
|
||||
the Free Software Foundation; either version 2 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program; if not, write to the Free Software
|
||||
Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) 19yy name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Library General
|
||||
Public License instead of this License.

|
||||
.SH DESCRIPTION
|
||||
Many programs read input from the user a line at a time. The GNU
|
||||
History library is able to keep track of those lines, associate arbitrary
|
||||
data with each line, and utilize information from previous lines in
|
||||
composing new ones.
|
||||
.PP
|
||||
.SH "HISTORY EXPANSION"
|
||||
.PP
|
||||
The history library supports a history expansion feature that
|
||||
is identical to the history expansion in
|
||||
.BR bash.
|
||||
This section describes what syntax features are available.
|
||||
.PP
|
||||
History expansions introduce words from the history list into
|
||||
the input stream, making it easy to repeat commands, insert the
|
||||
arguments to a previous command into the current input line, or
|
||||
fix errors in previous commands quickly.
|
||||
.PP
|
||||
History expansion is usually performed immediately after a complete line
|
||||
is read.
|
||||
It takes place in two parts.
|
||||
The first is to determine which line from the history list
|
||||
to use during substitution.
|
||||
The second is to select portions of that line for inclusion into
|
||||
the current one.
|
||||
The line selected from the history is the \fIevent\fP,
|
||||
and the portions of that line that are acted upon are \fIwords\fP.
|
||||
Various \fImodifiers\fP are available to manipulate the selected words.
|
||||
The line is broken into words in the same fashion as \fBbash\fP
|
||||
does when reading input,
|
||||
so that several words that would otherwise be separated
|
||||
are considered one word when surrounded by quotes (see the
|
||||
description of \fBhistory_tokenize()\fP below).
|
||||
History expansions are introduced by the appearance of the
|
||||
history expansion character, which is \^\fB!\fP\^ by default.
|
||||
Only backslash (\^\fB\e\fP\^) and single quotes can quote
|
||||
the history expansion character.
|
||||
.SS Event Designators
|
||||
.PP
|
||||
An event designator is a reference to a command line entry in the
|
||||
history list.
|
||||
Unless the reference is absolute, events are relative to the current
|
||||
position in the history list.
|
||||

.TP
|

.SS Word Designators
|

.PP
|

Word designators are used to select desired words from the event.
|
||||
A
|
||||
.B :
|
||||
separates the event specification from the word designator.
|
||||
It may be omitted if the word designator begins with a
|

.BR ^ ,
|

.BR $ ,
|
||||
.BR * ,
|
||||
.BR \- ,
|
||||
or
|
||||
.BR % .
|
||||
Words are numbered from the beginning of the line,
|
||||
with the first word being denoted by 0 (zero).
|
||||
Words are inserted into the current line separated by single spaces.
|

.B *
|
||||
if there is just one
|
||||
word in the event; the empty string is returned in that case.
|

.SH "PROGRAMMING WITH HISTORY FUNCTIONS"
|
||||
This section describes how to use the History library in other programs.
|
||||
.SS Introduction to History
|
||||
.PP
|
||||
The programmer using the History library has available functions
|
||||
for remembering lines on a history list, associating arbitrary data
|
||||
with a line, removing lines from the list, searching through the list
|
||||
for a line containing an arbitrary text string, and referencing any line
|
||||
in the list directly. In addition, a history \fIexpansion\fP function
|
||||
is available which provides for a consistent user interface across
|
||||
different programs.
|
||||
.PP
|
||||
The user using programs written with the History library has the
|
||||
benefit of a consistent user interface with a set of well-known
|
||||
commands for manipulating the text of previous lines and using that text
|
||||
in new commands. The basic history manipulation commands are
|
||||
identical to
|
||||
the history substitution provided by \fBbash\fP.
|
||||
.PP
|
||||
If the programmer desires, he can use the Readline library, which
|
||||
includes some history manipulation by default, and has the added
|
||||
advantage of command line editing.
|
||||
.PP
|
||||
Before declaring any functions using any functionality the History
|
||||
library provides in other code, an application writer should include
|
||||
the file
|
||||
.FN <readline/history.h>
|
||||
in any file that uses the
|
||||
History library's features. It supplies extern declarations for all
|
||||
of the library's public functions and variables, and declares all of
|
||||
the public data structures.

The history list is an array of history entries. A history entry is
|
||||
declared as follows:
|
||||
.PP
|
||||
.Vb "typedef void *" histdata_t;
|
||||
.PP
|
||||
.nf
|
||||
typedef struct _hist_entry {
|
||||
char *line;
|
||||
char *timestamp;
|
||||
histdata_t data;
|
||||
} HIST_ENTRY;
|
||||
.fi
|
||||
.PP
|
||||
The history list itself might therefore be declared as
|
||||
.PP
|
||||
.Vb "HIST_ENTRY **" the_history_list;
|
||||
.PP
|
||||
The state of the History library is encapsulated into a single structure:
|
||||
.PP
|
||||
.nf
|
||||
/*
|
||||
* A structure used to pass around the current state of the history.
|
||||
*/
|
||||
typedef struct _hist_state {
|
||||
HIST_ENTRY **entries; /* Pointer to the entries themselves. */
|
||||
int offset; /* The location pointer within this array. */
|
||||
int length; /* Number of elements within this array. */
|
||||
int size; /* Number of slots allocated to this array. */
|
||||
int flags;
|
||||
} HISTORY_STATE;
|
||||
.fi
|
||||
.PP
|
||||
If the flags member includes \fBHS_STIFLED\fP, the history has been
|
||||
stifled.
|
||||
.SH "History Functions"
|
||||
.PP
|
||||
This section describes the calling sequence for the various functions
|
||||
exported by the GNU History library.
|
||||
.SS Initializing History and State Management
|
||||
This section describes functions used to initialize and manage
|
||||
the state of the History library when you want to use the history
|
||||
functions in your program.
|
||||
|
||||
.Fn1 void using_history void
|
||||
Begin a session in which the history functions might be used. This
|
||||
initializes the interactive variables.
|
||||
|
||||
.Fn1 "HISTORY_STATE *" history_get_history_state void
|
||||
Return a structure describing the current state of the input history.
|
||||
|
||||
.Fn1 void history_set_history_state "HISTORY_STATE *state"
|
||||
Set the state of the history list according to \fIstate\fP.
|
||||
|
||||
.SS History List Management
|
||||
|
||||
These functions manage individual entries on the history list, or set
|
||||
parameters managing the list itself.
|
||||
|
||||
.Fn1 void add_history "const char *string"
|
||||
Place \fIstring\fP at the end of the history list. The associated data
|
||||
field (if any) is set to \fBNULL\fP.
|
||||
|
||||
.Fn1 void add_history_time "const char *string"
|
||||
Change the time stamp associated with the most recent history entry to
|
||||
\fIstring\fP.
|
||||
|
||||
.Fn1 "HIST_ENTRY *" remove_history "int which"
|
||||
Remove history entry at offset \fIwhich\fP from the history. The
|
||||
removed element is returned so you can free the line, data,
|
||||
and containing structure.
|
||||
|
||||
.Fn1 "histdata_t" free_history_entry "HIST_ENTRY *histent"
|
||||
Free the history entry \fIhistent\fP and any history library private
|
||||
data associated with it. Returns the application-specific data
|
||||
so the caller can dispose of it.
|
||||
|
||||
.Fn3 "HIST_ENTRY *" replace_history_entry "int which" "const char *line" "histdata_t data"
|
||||
Make the history entry at offset \fIwhich\fP have \fIline\fP and \fIdata\fP.
|
||||
This returns the old entry so the caller can dispose of any
|
||||
application-specific data. In the case
|
||||
of an invalid \fIwhich\fP, a \fBNULL\fP pointer is returned.
|
||||
|
||||
.Fn1 void clear_history "void"
|
||||
Clear the history list by deleting all the entries.
|
||||
|
||||
.Fn1 void stifle_history "int max"

||||
Stifle the history list, remembering only the last \fImax\fP entries.
|
||||
|
||||
.Fn1 int unstifle_history "void"
|
||||
Stop stifling the history. This returns the previously-set
|
||||
maximum number of history entries (as set by \fBstifle_history()\fP).
|
||||
history was stifled. The value is positive if the history was
|
||||
stifled, negative if it wasn't.
|
||||
|
||||
.Fn1 int history_is_stifled "void"
|
||||
Returns non-zero if the history is stifled, zero if it is not.
|
||||
|
||||
.SS Information About the History List
|
||||
|
||||
These functions return information about the entire history list or
|
||||
individual list entries.
|
||||
|
||||
.Fn1 "HIST_ENTRY **" history_list "void"
|
||||
Return a \fBNULL\fP terminated array of \fIHIST_ENTRY *\fP which is the
|
||||
current input history. Element 0 of this list is the beginning of time.
|
||||
If there is no history, return \fBNULL\fP.
|
||||
|
||||
.Fn1 int where_history "void"
|
||||
Returns the offset of the current history element.
|
||||
|
||||
.Fn1 "HIST_ENTRY *" current_history "void"
|
||||
Return the history entry at the current position, as determined by
|
||||
\fBwhere_history()\fP. If there is no entry there, return a \fBNULL\fP
|
||||
pointer.
|
||||
|
||||
.Fn1 "HIST_ENTRY *" history_get "int offset"
|
||||
Return the history entry at position \fIoffset\fP, starting from
|
||||
\fBhistory_base\fP.
|
||||
If there is no entry there, or if \fIoffset\fP
|
||||
is greater than the history length, return a \fBNULL\fP pointer.
|
||||
|
||||
.Fn1 "time_t" history_get_time "HIST_ENTRY *"
|
||||
Return the time stamp associated with the history entry passed as the argument.
|
||||
|
||||
.Fn1 int history_total_bytes "void"
|
||||
Return the number of bytes that the primary history entries are using.
|
||||
This function returns the sum of the lengths of all the lines in the
|
||||
history.
|
||||
|
||||
.SS Moving Around the History List
|
||||
|
||||
These functions allow the current index into the history list to be
|
||||
set or changed.
|
||||
|
||||
.Fn1 int history_set_pos "int pos"
|
||||
Set the current history offset to \fIpos\fP, an absolute index
|
||||
into the list.
|
||||
Returns 1 on success, 0 if \fIpos\fP is less than zero or greater
|
||||
than the number of history entries.
|
||||
|
||||
.Fn1 "HIST_ENTRY *" previous_history "void"
|
||||
Back up the current history offset to the previous history entry, and
|
||||
return a pointer to that entry. If there is no previous entry, return
|
||||
a \fBNULL\fP pointer.
|
||||
|
||||
.Fn1 "HIST_ENTRY *" next_history "void"
|
||||
Move the current history offset forward to the next history entry, and
|
||||
return the a pointer to that entry. If there is no next entry, return
|
||||
a \fBNULL\fP pointer.
|
||||
|
||||
.SS Searching the History List
|
||||
|
||||
These functions allow searching of the history list for entries containing
|
||||
a specific string. Searching may be performed both forward and backward
|
||||
from the current history position. The search may be \fIanchored\fP,
|
||||
meaning that the string must match at the beginning of the history entry.
|
||||
|
||||
.Fn2 int history_search "const char *string" "int direction"
|
||||
Search the history for \fIstring\fP, starting at the current history offset.
|
||||
If \fIdirection\fP is less than 0, then the search is through
|
||||
previous entries, otherwise through subsequent entries.
|
||||
If \fIstring\fP is found, then
|
||||
the current history index is set to that history entry, and the value
|
||||
returned is the offset in the line of the entry where
|
||||
\fIstring\fP was found. Otherwise, nothing is changed, and a -1 is
|
||||
returned.
|
||||
|
||||
.Fn2 int history_search_prefix "const char *string" "int direction"
|
||||
Search the history for \fIstring\fP, starting at the current history
|
||||
offset. The search is anchored: matching lines must begin with
|
||||
\fIstring\fP. If \fIdirection\fP is less than 0, then the search is
|
||||
through previous entries, otherwise through subsequent entries.
|
||||
If \fIstring\fP is found, then the
|
||||
current history index is set to that entry, and the return value is 0.
|
||||
Otherwise, nothing is changed, and a -1 is returned.
|
||||
|
||||
.Fn3 int history_search_pos "const char *string" "int direction" "int pos"
|
||||
Search for \fIstring\fP in the history list, starting at \fIpos\fP, an
|
||||
absolute index into the list. If \fIdirection\fP is negative, the search
|
||||
proceeds backward from \fIpos\fP, otherwise forward. Returns the absolute
|
||||
index of the history element where \fIstring\fP was found, or -1 otherwise.
|
||||
|
||||
.SS Managing the History File
|
||||
The History library can read the history from and write it to a file.
|
||||
This section documents the functions for managing a history file.
|
||||
|
||||
.Fn1 int read_history "const char *filename"
|
||||
Add the contents of \fIfilename\fP to the history list, a line at a time.
|
||||
If \fIfilename\fP is \fBNULL\fP, then read from \fI~/.history\fP.
|
||||
Returns 0 if successful, or \fBerrno\fP if not.
|
||||
|
||||
.Fn3 int read_history_range "const char *filename" "int from" "int to"
|
||||
Read a range of lines from \fIfilename\fP, adding them to the history list.
|
||||
Start reading at line \fIfrom\fP and end at \fIto\fP.
|
||||
If \fIfrom\fP is zero, start at the beginning. If \fIto\fP is less than
|
||||
\fIfrom\fP, then read until the end of the file. If \fIfilename\fP is
|
||||
\fBNULL\fP, then read from \fI~/.history\fP. Returns 0 if successful,
|
||||
or \fBerrno\fP if not.
|
||||
|
||||
.Fn1 int write_history "const char *filename"
|
||||
Write the current history to \fIfilename\fP, overwriting \fIfilename\fP
|
||||
if necessary.
|
||||
If \fIfilename\fP is \fBNULL\fP, then write the history list to \fI~/.history\fP.
|
||||
Returns 0 on success, or \fBerrno\fP on a read or write error.
|
||||
|
||||
|
||||
.Fn2 int append_history "int nelements" "const char *filename"
|
||||
Append the last \fInelements\fP of the history list to \fIfilename\fP.
|
||||
If \fIfilename\fP is \fBNULL\fP, then append to \fI~/.history\fP.
|
||||
Returns 0 on success, or \fBerrno\fP on a read or write error.
|
||||
|
||||
.Fn2 int history_truncate_file "const char *filename" "int nlines"
|
||||
Truncate the history file \fIfilename\fP, leaving only the last
|
||||
\fInlines\fP lines.
|
||||
If \fIfilename\fP is \fBNULL\fP, then \fI~/.history\fP is truncated.
|
||||
Returns 0 on success, or \fBerrno\fP on failure.
|
||||
|
||||
.SS History Expansion
|
||||
|
||||
These functions implement history expansion.
|
||||
|
||||
.Fn2 int history_expand "char *string" "char **output"
|
||||
Expand \fIstring\fP, placing the result into \fIoutput\fP, a pointer
|
||||
to a string. Returns:
|
||||
.RS
|
||||
.PD 0
|
||||
.TP
|
||||
0
|
||||
If no expansions took place (or, if the only change in
|
||||
the text was the removal of escape characters preceding the history expansion
|
||||
character);
|
||||
.TP
|
||||
1
|
||||
if expansions did take place;
|
||||
.TP
|
||||
-1
|
||||
if there was an error in expansion;
|
||||
.TP
|
||||
2
|
||||
if the returned line should be displayed, but not executed,
|
||||
as with the \fB:p\fP modifier.
|
||||
.PD
|
||||
.RE
|
||||
If an error ocurred in expansion, then \fIoutput\fP contains a descriptive
|
||||
error message.
|
||||
|
||||
.Fn3 "char *" get_history_event "const char *string" "int *cindex" "int qchar"
|
||||
Returns the text of the history event beginning at \fIstring\fP +
|
||||
\fI*cindex\fP. \fI*cindex\fP is modified to point to after the event
|
||||
specifier. At function entry, \fIcindex\fP points to the index into
|
||||
\fIstring\fP where the history event specification begins. \fIqchar\fP
|
||||
is a character that is allowed to end the event specification in addition
|
||||
to the ``normal'' terminating characters.
|
||||
|
||||
.Fn1 "char **" history_tokenize "const char *string"
|
||||
Return an array of tokens parsed out of \fIstring\fP, much as the
|
||||
shell might.
|
||||
The tokens are split on the characters in the
|
||||
\fBhistory_word_delimiters\fP variable,
|
||||
and shell quoting conventions are obeyed.
|
||||
|
||||
.Fn3 "char *" history_arg_extract "int first" "int last" "const char *string"
|
||||
Extract a string segment consisting of the \fIfirst\fP through \fIlast\fP
|
||||
arguments present in \fIstring\fP. Arguments are split using
|
||||
\fBhistory_tokenize()\fP.
|
||||
|
||||
.SS History Variables
|
||||
|
||||
This section describes the externally-visible variables exported by
|
||||
the GNU History Library.
|
||||
|
||||
.Vb int history_base
|
||||
The logical offset of the first entry in the history list.
|
||||
|
||||
.Vb int history_length
|
||||
The number of entries currently stored in the history list.
|
||||
|
||||
.Vb int history_max_entries
|
||||
The maximum number of history entries. This must be changed using
|
||||
\fBstifle_history()\fP.
|
||||
|
||||
.Vb int history_wite_timestamps
|
||||
If non-zero, timestamps are written to the history file, so they can be
|
||||
preserved between sessions. The default value is 0, meaning that
|
||||
timestamps are not saved.
|
||||
The current timestamp format uses the value of \fIhistory_comment_char\fP
|
||||
to delimit timestamp entries in the history file. If that variable does
|
||||
not have a value (the default), timestamps will not be written.
|
||||
|
||||
.Vb char history_expansion_char
|
||||
The character that introduces a history event. The default is \fB!\fP.
|
||||
Setting this to 0 inhibits history expansion.
|
||||
|
||||
.Vb char history_subst_char
|
||||
The character that invokes word substitution if found at the start of
|
||||
a line. The default is \fB^\fP.
|
||||
|
||||
.Vb char history_comment_char
|
||||
During tokenization, if this character is seen as the first character
|
||||
of a word, then it and all subsequent characters up to a newline are
|
||||
ignored, suppressing history expansion for the remainder of the line.
|
||||
This is disabled by default.
|
||||
|
||||
.Vb "char *" history_word_delimiters
|
||||
The characters that separate tokens for \fBhistory_tokenize()\fP.
|
||||
The default value is \fB"\ \et\en()<>;&|"\fP.
|
||||
|
||||
.Vb "char *" history_no_expand_chars
|
||||
The list of characters which inhibit history expansion if found immediately
|
||||
following \fBhistory_expansion_char\fP. The default is space, tab, newline,
|
||||
\fB\er\fP, and \fB=\fP.
|
||||
|
||||
.Vb "char *" history_search_delimiter_chars
|
||||
The list of additional characters which can delimit a history search
|
||||
string, in addition to space, tab, \fI:\fP and \fI?\fP in the case of
|
||||
a substring search. The default is empty.
|
||||
|
||||
.Vb int history_quotes_inhibit_expansion
|
||||
If non-zero, single-quoted words are not scanned for the history expansion
|
||||
character. The default value is 0.
|
||||
|
||||
.Vb "rl_linebuf_func_t *" history_inhibit_expansion_function
|
||||
This should be set to the address of a function that takes two arguments:
|
||||
a \fBchar *\fP (\fIstring\fP)
|
||||
and an \fBint\fP index into that string (\fIi\fP).
|
||||
It should return a non-zero value if the history expansion starting at
|
||||
\fIstring[i]\fP should not be performed; zero if the expansion should
|
||||
be done.
|
||||
It is intended for use by applications like \fBbash\fP that use the history
|
||||
expansion character for additional purposes.
|
||||
By default, this variable is set to \fBNULL\fP.

|

@section Introduction to History
|
||||
|
||||
Many programs read input from the user a line at a time. The @sc{gnu}
|
||||
History library is able to keep track of those lines, associate arbitrary
|
||||
data with each line, and utilize information from previous lines in
|
||||
composing new ones.
|
||||
|
||||
The programmer using the History library has available functions
|
||||
for remembering lines on a history list, associating arbitrary data
|
||||
with a line, removing lines from the list, searching through the list
|
||||
for a line containing an arbitrary text string, and referencing any line
|
||||
in the list directly. In addition, a history @dfn{expansion} function
|
||||
is available which provides for a consistent user interface across
|
||||
different programs.
|
||||
|
||||
The user using programs written with the History library has the
|
||||
benefit of a consistent user interface with a set of well-known
|
||||
commands for manipulating the text of previous lines and using that text
|
||||
in new commands. The basic history manipulation commands are similar to
|
||||
the history substitution provided by @code{csh}.
|
||||
|
||||
If the programmer desires, he can use the Readline library, which
|
||||
includes some history manipulation by default, and has the added
|
||||
advantage of command line editing.
|
||||
|
||||
Before declaring any functions using any functionality the History
|
||||
library provides in other code, an application writer should include
|
||||
the file @code{<readline/history.h>} in any file that uses the
|
||||
History library's features. It supplies extern declarations for all
|
||||
of the library's public functions and variables, and declares all of
|
||||
the public data structures.
|
||||
|
||||
@node History Storage
|
||||
@section History Storage
|
||||
|
||||
The history list is an array of history entries. A history entry is
|
||||
declared as follows:
|
||||

char *timestamp;
|

histdata_t data;
|

@} HIST_ENTRY;
|

@end example
|

@example
|

HIST_ENTRY **the_history_list;
|

@end example
|
||||
|
||||
The state of the History library is encapsulated into a single structure:
|
||||
|
||||
@example
|
||||
/*
|
||||
* A structure used to pass around the current state of the history.
|
||||
*/
|
||||
typedef struct _hist_state @{
|
||||
HIST_ENTRY **entries; /* Pointer to the entries themselves. */
|
||||
int offset; /* The location pointer within this array. */
|
||||
int length; /* Number of elements within this array. */
|
||||
int size; /* Number of slots allocated to this array. */
|
||||
int flags;
|
||||
@} HISTORY_STATE;
|
||||
@end example
|
||||
|
||||
If the flags member includes @code{HS_STIFLED}, the history has been
|
||||
stifled.

These functions allow searching of the history list for entries containing
|
||||
a specific string. Searching may be performed both forward and backward
|
||||
from the current history position. The search may be @dfn{anchored},
|
||||
meaning that the string must match at the beginning of the history entry.

@cindex anchored search
|
||||
|
||||
@deftypefun int history_search (const char *string, int direction)
|
||||
Search the history for @var{string}, starting at the current history offset.
|
||||
If @var{direction} is less than 0, then the search is through
|
||||
previous entries, otherwise through subsequent entries.
|
||||
If @var{string} is found, then
|
||||
the current history index is set to that history entry, and the value
|
||||
returned is the offset in the line of the entry where
|
||||
@var{string} was found. Otherwise, nothing is changed, and a -1 is
|

@end deftypefun
|
||||
|
||||
@deftypefun int history_search_prefix (const char *string, int direction)
|
||||
Search the history for @var{string}, starting at the current history
|
||||
offset. The search is anchored: matching lines must begin with
|
||||
@var{string}. If @var{direction} is less than 0, then the search is
|
||||
through previous entries, otherwise through subsequent entries.
|
||||
If @var{string} is found, then the
|
||||
current history index is set to that entry, and the return value is 0.
|
||||
Otherwise, nothing is changed, and a -1 is returned.
|
||||
@end deftypefun
|
||||
|
||||
@deftypefun int history_search_pos (const char *string, int direction, int pos)
|
||||
Search for @var{string} in the history list, starting at @var{pos}, an
|
||||
absolute index into the list. If @var{direction} is negative, the search
|
||||
proceeds backward from @var{pos}, otherwise forward. Returns the absolute
|
||||
index of the history element where @var{string} was found, or -1 otherwise.

@deftypefun int read_history_range (const char *filename, int from, int to)
|
||||
Read a range of lines from @var{filename}, adding them to the history list.
|
||||
Start reading at line @var{from} and end at @var{to}.
|
||||
If @var{from} is zero, start at the beginning. If @var{to} is less than
|
||||
@var{from}, then read until the end of the file. If @var{filename} is
|
||||
@code{NULL}, then read from @file{~/.history}. Returns 0 if successful,
|
||||
or @code{errno} if not.
|

@deftypefun int history_expand (char *string, char **output)
|
||||
Expand @var{string}, placing the result into @var{output}, a pointer
|

to a string (@pxref{History Interaction}). Returns:
|
||||
@table @code
|
||||
@item 0
|

@deftypefun {char *} get_history_event (const char *string, int *cindex, int qchar)
|
||||
Returns the text of the history event beginning at @var{string} +
|
||||
@var{*cindex}. @var{*cindex} is modified to point to after the event
|
||||
specifier. At function entry, @var{cindex} points to the index into
|
||||
@var{string} where the history event specification begins. @var{qchar}
|
||||
is a character that is allowed to end the event specification in addition
|

@code{stifle_history()}.
|
||||
@end deftypevar
|
||||
|
||||
@deftypevar int history_write_timestamps
|
||||
If non-zero, timestamps are written to the history file, so they can be
|

preserved between sessions. The default value is 0, meaning that
|
||||
timestamps are not saved.
|

@end deftypevar
|
||||
|
||||
@deftypevar char history_subst_char
|
||||
The character that invokes word substitution if found at the start of

||||
a line. The default is @samp{^}.
|
||||
@end deftypevar
|
||||
|
||||
@deftypevar char history_comment_char
|
||||
During tokenization, if this character is seen as the first character
|
||||
of a word, then it and all subsequent characters up to a newline are
|
||||
ignored, suppressing history expansion for the remainder of the line.
|
||||
This is disabled by default.
|
||||
@end deftypevar
|

|
||||
@end deftypevar
|
||||
|
||||
@deftypevar {char *} history_search_delimiter_chars
|
||||
The list of additional characters which can delimit a history search
|
||||
string, in addition to space, TAB, @samp{:} and @samp{?} in the case of
|
||||
a substring search. The default is empty.
|
||||
@end deftypevar
|
||||
|
||||
@deftypevar {char *} history_no_expand_chars
|
||||
The list of characters which inhibit history expansion if found immediately
|
||||
following @var{history_expansion_char}. The default is space, tab, newline,
|
||||
carriage return, and @samp{=}.
|
||||
@end deftypevar
|
||||
|
||||
@deftypevar int history_quotes_inhibit_expansion
|
||||
If non-zero, single-quoted words are not scanned for the history expansion

@deftypevar {rl_linebuf_func_t *} history_inhibit_expansion_function
|
||||
This should be set to the address of a function that takes two arguments:
|
||||
a @code{char *} (@var{string})
|
||||
and an @code{int} index into that string (@var{i}).
|
||||
It should return a non-zero value if the history expansion starting at
|
||||
@var{string[i]} should not be performed; zero if the expansion should
|
||||
be done.
|
||||
It is intended for use by applications like Bash that use the history
|
||||
expansion character for additional purposes.
|
||||
By default, this variable is set to @code{NULL}.

@cindex command history
|
||||
@cindex history list
|
||||
|
||||
When the @option{-o history} option to the @code{set} builtin
|
||||
is enabled (@pxref{The Set Builtin}),
|
||||
the shell provides access to the @dfn{command history},
|
||||
the list of commands previously typed.
|
||||
The value of the @env{HISTSIZE} shell variable is used as the
|
||||
number of commands to save in a history list.
|
||||
The text of the last @env{$HISTSIZE}
|
||||
commands (default 500) is saved.
|
||||
The shell stores each command in the history list prior to
|
||||
parameter and variable expansion
|
||||
but after history expansion is performed, subject to the
|
||||
values of the shell variables
|
||||
@env{HISTIGNORE} and @env{HISTCONTROL}.
|
||||
|
||||
When the shell starts up, the history is initialized from the
|
||||
file named by the @env{HISTFILE} variable (default @file{~/.bash_history}).
|
||||
The file named by the value of @env{HISTFILE} is truncated, if
|
||||
necessary, to contain no more than the number of lines specified by
|
||||
the value of the @env{HISTFILESIZE} variable.
|
||||
When an interactive shell exits, the last
|
||||
@env{$HISTSIZE} lines are copied from the history list to the file
|
||||
named by @env{$HISTFILE}.
|
||||
If the @code{histappend} shell option is set (@pxref{Bash Builtins}),
|
||||
the lines are appended to the history file,
|
||||
otherwise the history file is overwritten.
|
||||
If @env{HISTFILE}
|
||||
is unset, or if the history file is unwritable, the history is
|
||||
not saved. After saving the history, the history file is truncated
|
||||
to contain no more than @env{$HISTFILESIZE}
|
||||
lines. If @env{HISTFILESIZE} is not set, no truncation is performed.
|
||||
|
||||
If the @env{HISTTIMEFORMAT} is set, the time stamp information
|
||||
associated with each history entry is written to the history file,
|
||||
marked with the history comment character.
|
||||
When the history file is read, lines beginning with the history
|
||||
comment character followed immediately by a digit are interpreted
|
||||
as timestamps for the previous history line.
|
||||
|
||||
The builtin command @code{fc} may be used to list or edit and re-execute
|
||||
a portion of the history list.
|
||||
The @code{history} builtin may be used to display or modify the history
|
||||
list and manipulate the history file.
|
||||
When using command-line editing, search commands
|
||||
are available in each editing mode that provide access to the
|
||||
history list (@pxref{Commands For History}).
|
||||
|
||||
The shell allows control over which commands are saved on the history
|
||||
list. The @env{HISTCONTROL} and @env{HISTIGNORE}
|
||||
variables may be set to cause the shell to save only a subset of the
|
||||
commands entered.
|
||||
The @code{cmdhist}
|
||||
shell option, if enabled, causes the shell to attempt to save each
|
||||
line of a multi-line command in the same history entry, adding
|
||||
semicolons where necessary to preserve syntactic correctness.
|
||||
The @code{lithist}
|
||||
shell option causes the shell to save the command with embedded newlines
|
||||
instead of semicolons.
|
||||
The @code{shopt} builtin is used to set these options.
|
||||
@xref{Bash Builtins}, for a description of @code{shopt}.
|
||||
|
||||
@node Bash History Builtins

||||
@section Bash History Builtins
|
||||
@cindex history builtins
|
||||
|
||||
Bash provides two builtin commands which manipulate the
|
||||
history list and history file.
|
||||
|
||||
@table @code
|
||||
|
||||
@item fc
|
||||
@btindex fc
|
||||
@example
|
||||
@code{fc [-e @var{ename}] [-lnr] [@var{first}] [@var{last}]}
|
||||
@code{fc -s [@var{pat}=@var{rep}] [@var{command}]}
|
||||
@end example
|
||||
|
||||
Fix Command. In the first form, a range of commands from @var{first} to
|
||||
@var{last} is selected from the history list. Both @var{first} and
|
||||
@var{last} may be specified as a string (to locate the most recent
|
||||
command beginning with that string) or as a number (an index into the
|
||||
history list, where a negative number is used as an offset from the
|
||||
current command number). If @var{last} is not specified it is set to
|
||||
@var{first}. If @var{first} is not specified it is set to the previous
|
||||
command for editing and @minus{}16 for listing. If the @option{-l} flag is
|
||||
given, the commands are listed on standard output. The @option{-n} flag
|
||||
suppresses the command numbers when listing. The @option{-r} flag
|
||||
reverses the order of the listing. Otherwise, the editor given by
|
||||
@var{ename} is invoked on a file containing those commands. If
|
||||
@var{ename} is not given, the value of the following variable expansion
|
||||
is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}. This says to use the
|
||||
value of the @env{FCEDIT} variable if set, or the value of the
|
||||
@env{EDITOR} variable if that is set, or @code{vi} if neither is set.
|
||||
When editing is complete, the edited commands are echoed and executed.
|
||||
|
||||
In the second form, @var{command} is re-executed after each instance
|
||||
of @var{pat} in the selected command is replaced by @var{rep}.
|
||||
|
||||
A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so
|
||||
that typing @samp{r cc} runs the last command beginning with @code{cc}
|
||||
and typing @samp{r} re-executes the last command (@pxref{Aliases}).
|
||||
|
||||
@item history
|
||||
@btindex history
|
||||
@example
|
||||
history [@var{n}]
|
||||
history -c
|
||||
history -d @var{offset}
|
||||
history [-anrw] [@var{filename}]
|
||||
history -ps @var{arg}
|
||||
@end example
|
||||
|
||||
With no options, display the history list with line numbers.
|
||||
Lines prefixed with a @samp{*} have been modified.
|
||||
An argument of @var{n} lists only the last @var{n} lines.
|
||||
If the shell variable @env{HISTTIMEFORMAT} is set and not null,
|
||||
it is used as a format string for @var{strftime} to display
|
||||
the time stamp associated with each displayed history entry.
|
||||
No intervening blank is printed between the formatted time stamp
|
||||
and the history line.
|
||||
|
||||
Options, if supplied, have the following meanings:
|
||||
|
||||
@table @code
|
||||
@item -c
|
||||
Clear the history list. This may be combined
|
||||
with the other options to replace the history list completely.
|
||||
|
||||
@item -d @var{offset}
|
||||
Delete the history entry at position @var{offset}.
|
||||
@var{offset} should be specified as it appears when the history is
|
||||
displayed.
|
||||
|
||||
@item -a
|
||||
Append the new
|
||||
history lines (history lines entered since the beginning of the
|
||||
current Bash session) to the history file.
|
||||
|
||||
@item -n
|
||||
Append the history lines not already read from the history file
|
||||
to the current history list. These are lines appended to the history
|
||||
file since the beginning of the current Bash session.
|
||||
|
||||
@item -r
|
||||
Read the current history file and append its contents to
|
||||
the history list.
|
||||
|
||||
@item -w
|
||||
Write out the current history to the history file.
|
||||
|
||||
@item -p
|
||||
Perform history substitution on the @var{arg}s and display the result
|
||||
on the standard output, without storing the results in the history list.
|
||||
|
||||
@item -s
|
||||
The @var{arg}s are added to the end of
|
||||
the history list as a single entry.
|
||||
|
||||
@end table
|
||||
|
||||
When any of the @option{-w}, @option{-r}, @option{-a}, or @option{-n} options is
|
||||
used, if @var{filename}
|
||||
is given, then it is used as the history file. If not, then
|
||||
the value of the @env{HISTFILE} variable is used.

@section History Expansion
|
||||
@cindex history expansion
|
||||
|
||||
The History library provides a history expansion feature that is similar
|
||||
to the history expansion provided by @code{csh}. This section
|
||||
describes the syntax used to manipulate the history information.
|
||||
|
||||
History expansions introduce words from the history list into
|
||||
the input stream, making it easy to repeat commands, insert the
|
||||
arguments to a previous command into the current input line, or
|
||||
fix errors in previous commands quickly.
|
||||
|
||||
History expansion takes place in two parts. The first is to determine
|
||||
which line from the history list should be used during substitution.
|
||||
The second is to select portions of that line for inclusion into the
|
||||
current one. The line selected from the history is called the
|
||||
@dfn{event}, and the portions of that line that are acted upon are
|
||||
called @dfn{words}. Various @dfn{modifiers} are available to manipulate
|
||||
the selected words. The line is broken into words in the same fashion
|
||||
that Bash does, so that several words
|
||||
surrounded by quotes are considered one word.
|
||||
History expansions are introduced by the appearance of the
|
||||
history expansion character, which is @samp{!} by default.
|
||||
@ifset BashFeatures
|
||||
Only @samp{\} and @samp{'} may be used to escape the history expansion
|
||||
character.
|
||||
@end ifset
|
||||
|
||||
@ifset BashFeatures
|
||||
Several shell options settable with the @code{shopt}
|
||||
builtin (@pxref{Bash Builtins}) may be used to tailor
|
||||
the behavior of history expansion. If the
|
||||
@code{histverify} shell option is enabled, and Readline
|
||||
is being used, history substitutions are not immediately passed to
|
||||
the shell parser.
|
||||
Instead, the expanded line is reloaded into the Readline
|
||||
editing buffer for further modification.
|
||||
If Readline is being used, and the @code{histreedit}
|
||||
shell option is enabled, a failed history expansion will be
|
||||
reloaded into the Readline editing buffer for correction.
|
||||
The @option{-p} option to the @code{history} builtin command
|
||||
may be used to see what a history expansion will do before using it.
|
||||
The @option{-s} option to the @code{history} builtin may be used to
|
||||
add commands to the end of the history list without actually executing
|
||||
them, so that they are available for subsequent recall.
|
||||
This is most useful in conjunction with Readline.
|
||||
|
||||
The shell allows control of the various characters used by the
|
||||
history expansion mechanism with the @code{histchars} variable,
|
||||
as explained above (@pxref{Bash Variables}). The shell uses
|
||||
the history comment character to mark history timestamps when
|
||||
writing the history file.

@node Word Designators
|
||||
@subsection Word Designators
|
||||
|
||||
Word designators are used to select desired words from the event.
|
||||
A @samp{:} separates the event specification from the word designator. It
|
||||
may be omitted if the word designator begins with a @samp{^}, @samp{$},
|
||||
@samp{*}, @samp{-}, or @samp{%}. Words are numbered from the beginning
|
||||
of the line, with the first word being denoted by 0 (zero). Words are
|
||||
inserted into the current line separated by single spaces.
|
||||
|
||||
@need 0.75
|
||||
For example,
|
||||
|
||||
@table @code
|
||||
@item !!
|
||||
designates the preceding command. When you type this, the preceding
|
||||
command is repeated in toto.
|
||||
|
||||
@item !!:$
|
||||
designates the last argument of the preceding command. This may be
|
||||
shortened to @code{!$}.
|
||||
|
||||
@item !fi:2
|
||||
designates the second argument of the most recent command starting with
|
||||
the letters @code{fi}.
|
||||
@end table
|
||||
|
||||
@need 0.75
|
||||
Here are the word designators:
|
||||
|
||||
@table @code
|
||||
|
||||
@item 0 (zero)
|
||||
The @code{0}th word. For many applications, this is the command word.
|
||||
|
||||
@item @var{n}
|
||||
The @var{n}th word.
|
||||
|
||||
@item ^
|
||||
The first argument; that is, word 1.
|
||||
|
||||
@item $
|
||||
The last argument.
|
||||
|
||||
@item %
|
||||
The word matched by the most recent @samp{?@var{string}?} search.
|
||||
|
||||
@item @var{x}-@var{y}
|
||||
A range of words; @samp{-@var{y}} abbreviates @samp{0-@var{y}}.
|
||||
|
||||
@item *
|
||||
All of the words, except the @code{0}th. This is a synonym for @samp{1-$}.
|
||||
It is not an error to use @samp{*} if there is just one word in the event;
|
||||
the empty string is returned in that case.
|
||||
|
||||
@item @var{x}*
|
||||
Abbreviates @samp{@var{x}-$}
|
||||
|
||||
@item @var{x}-
|
||||
Abbreviates @samp{@var{x}-$} like @samp{@var{x}*}, but omits the last word.
|
||||
|
||||

@subsection Modifiers
|
||||
|

of the following modifiers, each preceded by a @samp{:}.
|
||||
|
||||
@table @code
|
||||
|

@item t
|
||||
Remove all leading pathname components, leaving the tail.
|
||||
|
||||
@item r
|
||||
Remove a trailing suffix of the form @samp{.@var{suffix}}, leaving
|
||||
the basename.
|
||||
|
||||
@item e
|
||||
Remove all but the trailing suffix.
|
||||
|
||||
@item p
|
||||
Print the new command but do not execute it.
|
||||
|
||||
@ifset BashFeatures
|
||||
@item q
|
||||
Quote the substituted words, escaping further substitutions.
|
||||
|
||||
@item x
|
||||
Quote the substituted words as with @samp{q},
|
||||
but break into words at spaces, tabs, and newlines.
|
||||
@end ifset
|
||||
|
||||
@item s/@var{old}/@var{new}/
|
||||
Substitute @var{new} for the first occurrence of @var{old} in the
|
||||
event line. Any delimiter may be used in place of @samp{/}.
|
||||
The delimiter may be quoted in @var{old} and @var{new}
|
||||
with a single backslash. If @samp{&} appears in @var{new},
|
||||
it is replaced by @var{old}. A single backslash will quote
|
||||
the @samp{&}. The final delimiter is optional if it is the last
|
||||
character on the input line.
|
||||
|
||||
@item &
|
||||
Repeat the previous substitution.
|
||||
|
||||
@item g
|
||||
@itemx a
|
||||
Cause changes to be applied over the entire event line. Used in
|
||||
conjunction with @samp{s}, as in @code{gs/@var{old}/@var{new}/},
|
||||
or with @samp{&}.
|
||||
|
