If +.B prompt +is \fBNULL\fP or the empty string, no prompt is issued. +The line returned is allocated with +.IR malloc (3); +the caller must free it when finished. The line returned +has the final newline removed, so only the text of the line +remains. +.LP +.B readline +offers editing capabilities while the user is entering the +line. +By default, the line editing commands +are similar to those of emacs. +A vi\-style line editing interface is also available. +.LP +This manual page describes only the most basic use of \fBreadline\fP. +Much more functionality is available; see +\fIThe GNU Readline Library\fP and \fIThe GNU History Library\fP +for additional information. +.SH RETURN VALUE +.LP +.B readline +returns the text of the line read. A blank line +returns the empty string. If +.B EOF +is encountered while reading a line, and the line is empty, +.B NULL +is returned. If an +.B EOF +is read with a non\-empty line, it is +treated as a newline. +.SH NOTATION +.LP +An emacs-style notation is used to denote +keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n +means Control\-N. Similarly, +.I meta +keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards +without a +.I meta +key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key +then the +.I x +key. This makes ESC the \fImeta prefix\fP. +The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP, +or press the Escape key +then hold the Control key while pressing the +.I x +key.) +.PP +Readline commands may be given numeric +.IR arguments , +which normally act as a repeat count. Sometimes, however, it is the +sign of the argument that is significant. Passing a negative argument +to a command that acts in the forward direction (e.g., \fBkill\-line\fP) +causes that command to act in a backward direction. Commands whose +behavior with arguments deviates from this are noted. +.PP +When a command is described as \fIkilling\fP text, the text +deleted is saved for possible future retrieval +(\fIyanking\fP). The killed text is saved in a +\fIkill ring\fP. Consecutive kills cause the text to be +accumulated into one unit, which can be yanked all at once. +Commands which do not kill text separate the chunks of text +on the kill ring. +.SH INITIALIZATION FILE +.LP +Readline is customized by putting commands in an initialization +file (the \fIinputrc\fP file). +The name of this file is taken from the value of the +.B INPUTRC +environment variable. If that variable is unset, the default is +.IR ~/.inputrc . +If that file does not exist or cannot be read, the ultimate default is +.IR /etc/inputrc . +When a program which uses the readline library starts up, the +init file is read, and the key bindings and variables are set. +There are only a few basic constructs allowed in the +readline init file. Blank lines are ignored. +Lines beginning with a \fB#\fP are comments. +Lines beginning with a \fB$\fP indicate conditional constructs. +Other lines denote key bindings and variable settings. +Each program using this library may add its own commands +and bindings. +.PP +For example, placing +.RS +.PP +M\-Control\-u: universal\-argument +.RE +or +.RS +C\-Meta\-u: universal\-argument +.RE +.sp +into the +.I inputrc +would make M\-C\-u execute the readline command +.IR universal\-argument . +.PP +The following symbolic character names are recognized while +processing key bindings: +.IR DEL , +.IR ESC , +.IR ESCAPE , +.IR LFD , +.IR NEWLINE , +.IR RET , +.IR RETURN , +.IR RUBOUT , +.IR SPACE , +.IR SPC , +and +.IR TAB . +.PP +In addition to command names, readline allows keys to be bound +to a string that is inserted when the key is pressed (a \fImacro\fP). +.PP +.SS Key Bindings +.PP +The syntax for controlling key bindings in the +.I inputrc +file is simple. All that is required is the name of the +command or the text of a macro and a key sequence to which +it should be bound. The name may be specified in one of two ways: +as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP +prefixes, or as a key sequence. +The name and key sequence are separated by a colon. There can be no +whitespace between the name and the colon. +.PP +When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP, +.I keyname +is the name of a key spelled out in English. For example: +.sp +.RS +Control\-u: universal\-argument +.br +Meta\-Rubout: backward\-kill\-word +.br +Control\-o: "> output" +.RE +.LP +In the above example, +.I C\-u +is bound to the function +.BR universal\-argument , +.I M-DEL +is bound to the function +.BR backward\-kill\-word , +and +.I C\-o +is bound to run the macro +expressed on the right hand side (that is, to insert the text +.if t \f(CW> output\fP +.if n ``> output'' +into the line). +.PP +In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP, +.B keyseq +differs from +.B keyname +above in that strings denoting +an entire key sequence may be specified by placing the sequence +within double quotes. Some GNU Emacs style key escapes can be +used, as in the following example, but the symbolic character names +are not recognized. +.sp +.RS +"\eC\-u": universal\-argument +.br +"\eC\-x\eC\-r": re\-read\-init\-file +.br +"\ee[11~": "Function Key 1" +.RE +.PP +In this example, +.I C-u +is again bound to the function +.BR universal\-argument . +.I "C-x C-r" +is bound to the function +.BR re\-read\-init\-file , +and +.I "ESC [ 1 1 ~" +is bound to insert the text +.if t \f(CWFunction Key 1\fP. +.if n ``Function Key 1''. +.PP +The full set of GNU Emacs style escape sequences available when specifying +key sequences is +.RS +.PD 0 +.TP +.B \eC\- +control prefix +.TP +.B \eM\- +meta prefix +.TP +.B \ee +an escape character +.TP +.B \e\e +backslash +.TP +.B \e" +literal ", a double quote +.TP +.B \e' +literal ', a single quote +.RE +.PD +.PP +In addition to the GNU Emacs style escape sequences, a second +set of backslash escapes is available: +.RS +.PD 0 +.TP +.B \ea +alert (bell) +.TP +.B \eb +backspace +.TP +.B \ed +delete +.TP +.B \ef +form feed +.TP +.B \en +newline +.TP +.B \er +carriage return +.TP +.B \et +horizontal tab +.TP +.B \ev +vertical tab +.TP +.B \e\fInnn\fP +the eight-bit character whose value is the octal value \fInnn\fP +(one to three digits) +.TP +.B \ex\fIHH\fP +the eight-bit character whose value is the hexadecimal value \fIHH\fP +(one or two hex digits) +.RE +.PD +.PP +When entering the text of a macro, single or double quotes should +be used to indicate a macro definition. Unquoted text +is assumed to be a function name. +In the macro body, the backslash escapes described above are expanded. +Backslash will quote any other character in the macro text, +including " and '. +.PP +.B Bash +allows the current readline key bindings to be displayed or modified +with the +.B bind +builtin command.

The +.I inputrc +file may be edited and re-read if a program does not provide +any other means to incorporate new bindings. +.SS Variables +.PP +Readline has variables that can be used to further customize its +behavior. A variable may be set in the +.I inputrc +file with a statement of the form +.RS +.PP +\fBset\fP \fIvariable\-name\fP \fIvalue\fP +.RE +.PP +Except where noted, readline variables can take the values +.B On +or +.B Off +(without regard to case). +Unrecognized variable names are ignored. +When a variable value is read, empty or null values, "on" (case-insensitive), +and "1" are equivalent to \fBOn\fP. All other values are equivalent to +\fBOff\fP. +The variables and their default values are: +.PP +.PD 0 +.TP +.B bell\-style (audible) +Controls what happens when readline wants to ring the terminal bell. +If set to \fBnone\fP, readline never rings the bell.

When set to a +value greater than zero, common prefixes longer than this value are +replaced with an ellipsis when displaying possible completions. +.TP +.B completion\-query\-items (100) +This determines when the user is queried about viewing +the number of possible completions +generated by the \fBpossible\-completions\fP command. +It may be set to any integer value greater than or equal to +zero. If the number of possible completions is greater than +or equal to the value of this variable, the user is asked whether +or not he wishes to view them; otherwise they are simply listed +on the terminal. A negative value causes readline to never ask. +.TP +.B convert\-meta (On) +If set to \fBOn\fP, readline will convert characters with the +eighth bit set to an ASCII key sequence +by stripping the eighth bit and prefixing it with an +escape character (in effect, using escape as the \fImeta prefix\fP). +.TP +.B disable\-completion (Off) +If set to \fBOn\fP, readline will inhibit word completion. Completion +characters will be inserted into the line as if they had been +mapped to \fBself-insert\fP. +.TP +.B editing\-mode (emacs) +Controls whether readline begins with a set of key bindings similar +to emacs or vi. +.B editing\-mode +can be set to either +.B emacs +or +.BR vi . +.TP +.B enable\-keypad (Off) +When set to \fBOn\fP, readline will try to enable the application +keypad when it is called. Some systems need this to enable the +arrow keys. +.TP +.B expand\-tilde (Off) +If set to \fBon\fP, tilde expansion is performed when readline +attempts word completion. +.TP +.B history\-preserve\-point (Off) +If set to \fBon\fP, the history code attempts to place point at the +same location on each history line retrieved with \fBprevious-history\fP +or \fBnext-history\fP. +.TP +.B history\-size (0) +Set the maximum number of history entries saved in the history list. If +set to zero, the number of entries in the history list is not limited. +.TP +.B horizontal\-scroll\-mode (Off) +When set to \fBOn\fP, makes readline use a single line for display, +scrolling the input horizontally on a single screen line when it +becomes longer than the screen width rather than wrapping to a new line. +.TP +.B input\-meta (Off) +If set to \fBOn\fP, readline will enable eight-bit input (that is, +it will not clear the eighth bit in the characters it reads), +regardless of what the terminal claims it can support. The name +.B meta\-flag +is a synonym for this variable. +.TP +.B isearch\-terminators (``C\-[ C\-J'') +The string of characters that should terminate an incremental +search without subsequently executing the character as a command. +If this variable has not been given a value, the characters +\fIESC\fP and \fIC\-J\fP will terminate an incremental search. +.TP +.B keymap (emacs) +Set the current readline keymap. The set of legal keymap names is +\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move, +vi-command\fP, and +.IR vi-insert . +\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is +equivalent to \fIemacs-standard\fP. The default value is +.IR emacs . +The value of +.B editing\-mode +also affects the default keymap. +.TP +.B mark\-directories (On) +If set to \fBOn\fP, completed directory names have a slash +appended. +.TP +.B mark\-modified\-lines (Off) +If set to \fBOn\fP, history lines that have been modified are displayed +with a preceding asterisk (\fB*\fP). +.TP +.B mark\-symlinked\-directories (Off) +If set to \fBOn\fP, completed names which are symbolic links to directories +have a slash appended (subject to the value of +\fBmark\-directories\fP). +.TP +.B match\-hidden\-files (On) +This variable, when set to \fBOn\fP, causes readline to match files whose +names begin with a `.' (hidden files) when performing filename +completion, unless the leading `.' is +supplied by the user in the filename to be completed. +.TP +.B output\-meta (Off) +If set to \fBOn\fP, readline will display characters with the +eighth bit set directly rather than as a meta-prefixed escape +sequence. +.TP +.B page\-completions (On) +If set to \fBOn\fP, readline uses an internal \fImore\fP-like pager +to display a screenful of possible completions at a time. +.TP +.B print\-completions\-horizontally (Off) +If set to \fBOn\fP, readline will display completions with matches +sorted horizontally in alphabetical order, rather than down the screen. +.TP +.B revert\-all\-at\-newline (Off) +If set to \fBon\fP, readline will undo all changes to history lines +before returning when \fBaccept\-line\fP is executed. By default, +history lines may be modified and retain individual undo lists across +calls to \fBreadline\fP. +.TP +.B show\-all\-if\-ambiguous (Off) +This alters the default behavior of the completion functions. If +set to +.BR on , +words which have more than one possible completion cause the +matches to be listed immediately instead of ringing the bell. +.TP +.B show\-all\-if\-unmodified (Off) +This alters the default behavior of the completion functions in +a fashion similar to \fBshow\-all\-if\-ambiguous\fP. +If set to +.BR on , +words which have more than one possible completion without any +possible partial completion (the possible completions don't share +a common prefix) cause the matches to be listed immediately instead +of ringing the bell. +.TP +.B visible\-stats (Off) +If set to \fBOn\fP, a character denoting a file's type as reported +by \fIstat\fP(2) is appended to the filename when listing possible +completions. +.PD +.SS Conditional Constructs +.PP +Readline implements a facility similar in spirit to the conditional +compilation features of the C preprocessor which allows key +bindings and variable settings to be performed as the result +of tests. There are four parser directives used. +.IP \fB$if\fP +The +.B $if +construct allows bindings to be made based on the +editing mode, the terminal being used, or the application using +readline. The text of the test extends to the end of the line; +no characters are required to isolate it. +.RS +.IP \fBmode\fP +The \fBmode=\fP form of the \fB$if\fP directive is used to test +whether readline is in emacs or vi mode. +This may be used in conjunction +with the \fBset keymap\fP command, for instance, to set bindings in +the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if +readline is starting out in emacs mode. +.IP \fBterm\fP +The \fBterm=\fP form may be used to include terminal-specific +key bindings, perhaps to bind the key sequences output by the +terminal's function keys. The word on the right side of the +.B = +is tested against the full name of the terminal and the portion +of the terminal name before the first \fB\-\fP. This allows +.I sun +to match both +.I sun +and +.IR sun\-cmd , +for instance. +.IP \fBapplication\fP +The \fBapplication\fP construct is used to include +application-specific settings. Each program using the readline +library sets the \fIapplication name\fP, and an initialization +file can test for a particular value. +This could be used to bind key sequences to functions useful for +a specific program. For instance, the following command adds a +key sequence that quotes the current or previous word in Bash: +.sp 1 +.RS +.nf +\fB$if\fP Bash +# Quote the current or previous word +"\eC-xq": "\eeb\e"\eef\e"" +\fB$endif\fP +.fi +.RE +.RE +.IP \fB$endif\fP +This command, as seen in the previous example, terminates an +\fB$if\fP command. +.IP \fB$else\fP +Commands in this branch of the \fB$if\fP directive are executed if +the test fails. +.IP \fB$include\fP +This directive takes a single filename as an argument and reads commands +and bindings from that file. For example, the following directive +would read \fI/etc/inputrc\fP: +.sp 1 +.RS +.nf +\fB$include\fP \^ \fI/etc/inputrc\fP +.fi +.RE +.SH SEARCHING +.PP +Readline provides commands for searching through the command history +for lines containing a specified string. +There are two search modes: +.I incremental +and +.IR non-incremental . +.PP +Incremental searches begin before the user has finished typing the +search string. +As each character of the search string is typed, readline displays +the next entry from the history matching the string typed so far. +An incremental search requires only as many characters as needed to +find the desired history entry. +To search backward in the history for a particular string, type +\fBC\-r\fP. Typing \fBC\-s\fP searches forward through the history. +The characters present in the value of the \fBisearch-terminators\fP +variable are used to terminate an incremental search. +If that variable has not been assigned a value the \fIEscape\fP and +\fBC\-J\fP characters will terminate an incremental search. +\fBC\-G\fP will abort an incremental search and restore the original +line. +When the search is terminated, the history entry containing the +search string becomes the current line. +.PP +To find other matching entries in the history list, type \fBC\-s\fP or +\fBC\-r\fP as appropriate. +This will search backward or forward in the history for the next +line matching the search string typed so far. +Any other key sequence bound to a readline command will terminate +the search and execute that command. +For instance, a newline will terminate the search and accept +the line, thereby executing the command from the history list. +A movement command will terminate the search, make the last line found +the current line, and begin editing. +.PP +Non-incremental searches read the entire search string before starting +to search for matching history lines. The search string may be +typed by the user or be part of the contents of the current line. +.SH EDITING COMMANDS +.PP +The following is a list of the names of the commands and the default +key sequences to which they are bound. +Command names without an accompanying key sequence are unbound by default. +.PP +In the following descriptions, \fIpoint\fP refers to the current cursor +position, and \fImark\fP refers to a cursor position saved by the +\fBset\-mark\fP command. +The text between the point and mark is referred to as the \fIregion\fP. +.SS Commands for Moving +.PP +.PD 0 +.TP +.B beginning\-of\-line (C\-a) +Move to the start of the current line. +.TP +.B end\-of\-line (C\-e) +Move to the end of the line. +.TP +.B forward\-char (C\-f) +Move forward a character. +.TP +.B backward\-char (C\-b) +Move back a character. +.TP +.B forward\-word (M\-f) +Move forward to the end of the next word. Words are composed of +alphanumeric characters (letters and digits). +.TP +.B backward\-word (M\-b) +Move back to the start of the current or previous word. Words are +composed of alphanumeric characters (letters and digits). +.TP +.B clear\-screen (C\-l) +Clear the screen leaving the current line at the top of the screen. +With an argument, refresh the current line without clearing the +screen. +.TP +.B redraw\-current\-line +Refresh the current line. +.PD +.SS Commands for Manipulating the History +.PP +.PD 0 +.TP +.B accept\-line (Newline, Return) +Accept the line regardless of where the cursor is. +If this line is +non-empty, it may be added to the history list for future recall with +\fBadd_history()\fP. +If the line is a modified history line, the history line is restored to its original state. +.TP +.B previous\-history (C\-p) +Fetch the previous command from the history list, moving back in +the list. +.TP +.B next\-history (C\-n) +Fetch the next command from the history list, moving forward in the +list. +.TP +.B beginning\-of\-history (M\-<) +Move to the first line in the history. +.TP +.B end\-of\-history (M\->) +Move to the end of the input history, i.e., the line currently being +entered. +.TP +.B reverse\-search\-history (C\-r) +Search backward starting at the current line and moving `up' through +the history as necessary. This is an incremental search. +.TP +.B forward\-search\-history (C\-s) +Search forward starting at the current line and moving `down' through +the history as necessary. This is an incremental search. +.TP +.B non\-incremental\-reverse\-search\-history (M\-p) +Search backward through the history starting at the current line +using a non-incremental search for a string supplied by the user. +.TP +.B non\-incremental\-forward\-search\-history (M\-n) +Search forward through the history using a non-incremental search +for a string supplied by the user. +.TP +.B history\-search\-forward +Search forward through the history for the string of characters +between the start of the current line and the current cursor +position (the \fIpoint\fP). +This is a non-incremental search. +.TP +.B history\-search\-backward +Search backward through the history for the string of characters +between the start of the current line and the point. +This is a non-incremental search. +.TP +.B yank\-nth\-arg (M\-C\-y) +Insert the first argument to the previous command (usually +the second word on the previous line) at point. +With an argument +.IR n , +insert the \fIn\fPth word from the previous command (the words +in the previous command begin with word 0). A negative argument +inserts the \fIn\fPth word from the end of the previous command. +Once the argument \fIn\fP is computed, the argument is extracted +as if the "!\fIn\fP" history expansion had been specified. +.TP +.B +yank\-last\-arg (M\-.\^, M\-_\^) +Insert the last argument to the previous command (the last word of +the previous history entry). With an argument, +behave exactly like \fByank\-nth\-arg\fP. +Successive calls to \fByank\-last\-arg\fP move back through the history +list, inserting the last argument of each line in turn. +The history expansion facilities are used to extract the last argument, +as if the "!$" history expansion had been specified. +.PD +.SS Commands for Changing Text +.PP +.PD 0 +.TP +.B delete\-char (C\-d) +Delete the character at point. If point is at the +beginning of the line, there are no characters in the line, and +the last character typed was not bound to \fBdelete\-char\fP, then return +.SM +.BR EOF . +.TP +.B backward\-delete\-char (Rubout) +Delete the character behind the cursor. When given a numeric argument, +save the deleted text on the kill ring. +.TP +.B forward\-backward\-delete\-char +Delete the character under the cursor, unless the cursor is at the +end of the line, in which case the character behind the cursor is +deleted. +.TP +.B quoted\-insert (C\-q, C\-v) +Add the next character that you type to the line verbatim. This is +how to insert characters like \fBC\-q\fP, for example. +.TP +.B tab\-insert (M-TAB) +Insert a tab character. +.TP +.B self\-insert (a,\ b,\ A,\ 1,\ !,\ ...) +Insert the character typed. +.TP +.B transpose\-chars (C\-t) +Drag the character before point forward over the character at point, +moving point forward as well. +If point is at the end of the line, then this transposes +the two characters before point. +Negative arguments have no effect. +.TP +.B transpose\-words (M\-t) +Drag the word before point past the word after point, +moving point over that word as well. +If point is at the end of the line, this transposes +the last two words on the line. +.TP +.B upcase\-word (M\-u) +Uppercase the current (or following) word. With a negative argument, +uppercase the previous word, but do not move point. +.TP +.B downcase\-word (M\-l) +Lowercase the current (or following) word. With a negative argument, +lowercase the previous word, but do not move point. +.TP +.B capitalize\-word (M\-c) +Capitalize the current (or following) word. With a negative argument, +capitalize the previous word, but do not move point. +.TP +.B overwrite\-mode +Toggle overwrite mode. With an explicit positive numeric argument, +switches to overwrite mode. With an explicit non-positive numeric +argument, switches to insert mode. This command affects only +\fBemacs\fP mode; \fBvi\fP mode does overwrite differently. +Each call to \fIreadline()\fP starts in insert mode. +In overwrite mode, characters bound to \fBself\-insert\fP replace +the text at point rather than pushing the text to the right. +Characters bound to \fBbackward\-delete\-char\fP replace the character +before point with a space. By default, this command is unbound. +.PD +.SS Killing and Yanking +.PP +.PD 0 +.TP +.B kill\-line (C\-k) +Kill the text from point to the end of the line. +.TP +.B backward\-kill\-line (C\-x Rubout) +Kill backward to the beginning of the line. +.TP +.B unix\-line\-discard (C\-u) +Kill backward from point to the beginning of the line. +The killed text is saved on the kill-ring. +.\" There is no real difference between this and backward-kill-line +.TP +.B kill\-whole\-line +Kill all characters on the current line, no matter where point is. +.TP +.B kill\-word (M\-d) +Kill from point the end of the current word, or if between +words, to the end of the next word. Word boundaries are the same as +those used by \fBforward\-word\fP. +.TP +.B backward\-kill\-word (M\-Rubout) +Kill the word behind point. +Word boundaries are the same as those used by \fBbackward\-word\fP. +.TP +.B unix\-word\-rubout (C\-w) +Kill the word behind point, using white space as a word boundary. +The killed text is saved on the kill-ring. +.TP +.B unix\-filename\-rubout +Kill the word behind point, using white space and the slash character +as the word boundaries. +The killed text is saved on the kill-ring. +.TP +.B delete\-horizontal\-space (M\-\e) +Delete all spaces and tabs around point. +.TP +.B kill\-region +Kill the text between the point and \fImark\fP (saved cursor position). +This text is referred to as the \fIregion\fP. +.TP +.B copy\-region\-as\-kill +Copy the text in the region to the kill buffer. +.TP +.B copy\-backward\-word +Copy the word before point to the kill buffer. +The word boundaries are the same as \fBbackward\-word\fP. +.TP +.B copy\-forward\-word +Copy the word following point to the kill buffer. +The word boundaries are the same as \fBforward\-word\fP. +.TP +.B yank (C\-y) +Yank the top of the kill ring into the buffer at point. +.TP +.B yank\-pop (M\-y) +Rotate the kill ring, and yank the new top. Only works following +.B yank +or +.BR yank\-pop . +.PD +.SS Numeric Arguments +.PP +.PD 0 +.TP +.B digit\-argument (M\-0, M\-1, ..., M\-\-) +Add this digit to the argument already accumulating, or start a new +argument. M\-\- starts a negative argument. +.TP +.B universal\-argument +This is another way to specify an argument. +If this command is followed by one or more digits, optionally with a +leading minus sign, those digits define the argument. +If the command is followed by digits, executing +.B universal\-argument +again ends the numeric argument, but is otherwise ignored. +As a special case, if this command is immediately followed by a +character that is neither a digit or minus sign, the argument count +for the next command is multiplied by four. +The argument count is initially one, so executing this function the +first time makes the argument count four, a second time makes the +argument count sixteen, and so on. +.PD +.SS Completing +.PP +.PD 0 +.TP +.B complete (TAB) +Attempt to perform completion on the text before point. +The actual completion performed is application-specific. +.BR Bash , +for instance, attempts completion treating the text as a variable +(if the text begins with \fB$\fP), username (if the text begins with +\fB~\fP), hostname (if the text begins with \fB@\fP), or +command (including aliases and functions) in turn. If none +of these produces a match, filename completion is attempted. +.BR Gdb , +on the other hand, +allows completion of program functions and variables, and +only attempts filename completion under certain circumstances. +.TP +.B possible\-completions (M\-?) +List the possible completions of the text before point. +.TP +.B insert\-completions (M\-*) +Insert all completions of the text before point +that would have been generated by +\fBpossible\-completions\fP. +.TP +.B menu\-complete +Similar to \fBcomplete\fP, but replaces the word to be completed +with a single match from the list of possible completions. +Repeated execution of \fBmenu\-complete\fP steps through the list +of possible completions, inserting each match in turn. +At the end of the list of completions, the bell is rung +(subject to the setting of \fBbell\-style\fP) +and the original text is restored. +An argument of \fIn\fP moves \fIn\fP positions forward in the list +of matches; a negative argument may be used to move backward +through the list. +This command is intended to be bound to \fBTAB\fP, but is unbound +by default. +.TP +.B menu\-complete-\backward +Identical to \fBmenu\-complete\fP, but moves backward through the list +of possible completions, as if \fBmenu\-complete\fP had been given a +negative argument. This command is unbound by default. +.TP +.B delete\-char\-or\-list +Deletes the character under the cursor if not at the beginning or +end of the line (like \fBdelete-char\fP). +If at the end of the line, behaves identically to +\fBpossible-completions\fP. +.PD +.SS Keyboard Macros +.PP +.PD 0 +.TP +.B start\-kbd\-macro (C\-x (\^) +Begin saving the characters typed into the current keyboard macro. +.TP +.B end\-kbd\-macro (C\-x )\^) +Stop saving the characters typed into the current keyboard macro +and store the definition. +.TP +.B call\-last\-kbd\-macro (C\-x e) +Re-execute the last keyboard macro defined, by making the characters +in the macro appear as if typed at the keyboard. +.PD +.SS Miscellaneous +.PP +.PD 0 +.TP +.B re\-read\-init\-file (C\-x C\-r) +Read in the contents of the \fIinputrc\fP file, and incorporate +any bindings or variable assignments found there. +.TP +.B abort (C\-g) +Abort the current editing command and +ring the terminal's bell (subject to the setting of +.BR bell\-style ). +.TP +.B do\-uppercase\-version (M\-a, M\-b, M\-\fIx\fP, ...) +If the metafied character \fIx\fP is lowercase, run the command +that is bound to the corresponding uppercase character. +.TP +.B prefix\-meta (ESC) +Metafy the next character typed. +.SM +.B ESC +.B f +is equivalent to +.BR Meta\-f . +.TP +.B undo (C\-_, C\-x C\-u) +Incremental undo, separately remembered for each line. +.TP +.B revert\-line (M\-r) +Undo all changes made to this line. This is like executing the +.B undo +command enough times to return the line to its initial state. +.TP +.B tilde\-expand (M\-&) +Perform tilde expansion on the current word. +.TP +.B set\-mark (C\-@, M\-) +Set the mark to the point. If a +numeric argument is supplied, the mark is set to that position. +.TP +.B exchange\-point\-and\-mark (C\-x C\-x) +Swap the point with the mark. The current cursor position is set to +the saved position, and the old cursor position is saved as the mark. +.TP +.B character\-search (C\-]) +A character is read and point is moved to the next occurrence of that +character. A negative count searches for previous occurrences. +.TP +.B character\-search\-backward (M\-C\-]) +A character is read and point is moved to the previous occurrence of that +character. A negative count searches for subsequent occurrences. +.TP +.B skip\-csi\-sequence () +Read enough characters to consume a multi-key sequence such as those +defined for keys like Home and End. Such sequences begin with a +Control Sequence Indicator (CSI), usually ESC\-[. If this sequence is +bound to "\e[", keys producing such sequences will have no effect +unless explicitly bound to a readline command, instead of inserting +stray characters into the editing buffer. This is unbound by default, +but usually bound to ESC\-[. +.TP +.B insert\-comment (M\-#) +Without a numeric argument, the value of the readline +.B comment\-begin +variable is inserted at the beginning of the current line. +If a numeric argument is supplied, this command acts as a toggle: if +the characters at the beginning of the line do not match the value +of \fBcomment\-begin\fP, the value is inserted, otherwise +the characters in \fBcomment-begin\fP are deleted from the beginning of +the line. +In either case, the line is accepted as if a newline had been typed. +The default value of +.B comment\-begin +makes the current line a shell comment. +If a numeric argument causes the comment character to be removed, the line +will be executed by the shell. +.TP +.B dump\-functions +Print all of the functions and their key bindings to the +readline output stream. If a numeric argument is supplied, +the output is formatted in such a way that it can be made part +of an \fIinputrc\fP file. +.TP +.B dump\-variables +Print all of the settable variables and their values to the +readline output stream.

Specifically, +@key{DEL}, @key{ESC}, @key{LFD}, @key{SPC}, @key{RET}, and @key{TAB} all +stand for themselves when seen in this text, or in an init file +(@pxref{Readline Init File}). +If your keyboard lacks a @key{LFD} key, typing @key{C-j} will +produce the desired character. +The @key{RET} key may be labeled @key{Return} or @key{Enter} on +some keyboards. + +@node Readline Interaction +@section Readline Interaction +@cindex interaction, readline + +Often during an interactive session you type in a long line of text, +only to notice that the first word on the line is misspelled. The +Readline library gives you a set of commands for manipulating the text +as you type it in, allowing you to just fix your typo, and not forcing +you to retype the majority of the line. Using these editing commands, +you move the cursor to the place that needs correction, and delete or +insert the text of the corrections. Then, when you are satisfied with +the line, you simply press @key{RET}. You do not have to be at the +end of the line to press @key{RET}; the entire line is accepted +regardless of the location of the cursor within the line. + +@menu +* Readline Bare Essentials:: The least you need to know about Readline. +* Readline Movement Commands:: Moving about the input line. +* Readline Killing Commands:: How to delete text, and how to get it back! +* Readline Arguments:: Giving numeric arguments to commands. +* Searching:: Searching through previous lines. +@end menu + +@node Readline Bare Essentials +@subsection Readline Bare Essentials +@cindex notation, readline +@cindex command editing +@cindex editing command lines + +In order to enter characters into the line, simply type them. The typed +character appears where the cursor was, and then the cursor moves one +space to the right. If you mistype a character, you can use your +erase character to back up and delete the mistyped character. + +Sometimes you may mistype a character, and +not notice the error until you have typed several other characters. In +that case, you can type @kbd{C-b} to move the cursor to the left, and then +correct your mistake. Afterwards, you can move the cursor to the right +with @kbd{C-f}. + +When you add text in the middle of a line, you will notice that characters +to the right of the cursor are `pushed over' to make room for the text +that you have inserted. Likewise, when you delete text behind the cursor, +characters to the right of the cursor are `pulled back' to fill in the +blank space created by the removal of the text. A list of the bare +essentials for editing the text of an input line follows. + +@table @asis +@item @kbd{C-b} +Move back one character. +@item @kbd{C-f} +Move forward one character. +@item @key{DEL} or @key{Backspace} +Delete the character to the left of the cursor. +@item @kbd{C-d} +Delete the character underneath the cursor. +@item @w{Printing characters} +Insert the character into the line at the cursor. +@item @kbd{C-_} or @kbd{C-x C-u} +Undo the last editing command. You can undo all the way back to an +empty line. +@end table + +@noindent +(Depending on your configuration, the @key{Backspace} key be set to +delete the character to the left of the cursor and the @key{DEL} key set +to delete the character underneath the cursor, like @kbd{C-d}, rather +than the character to the left of the cursor.) + +@node Readline Movement Commands +@subsection Readline Movement Commands + + +The above table describes the most basic keystrokes that you need +in order to do editing of the input line. For your convenience, many +other commands have been added in addition to @kbd{C-b}, @kbd{C-f}, +@kbd{C-d}, and @key{DEL}. Here are some commands for moving more rapidly +about the line. + +@table @kbd +@item C-a +Move to the start of the line. +@item C-e +Move to the end of the line. +@item M-f +Move forward a word, where a word is composed of letters and digits. +@item M-b +Move backward a word. +@item C-l +Clear the screen, reprinting the current line at the top. +@end table + +Notice how @kbd{C-f} moves forward a character, while @kbd{M-f} moves +forward a word. It is a loose convention that control keystrokes +operate on characters while meta keystrokes operate on words. + +@node Readline Killing Commands +@subsection Readline Killing Commands + +@cindex killing text +@cindex yanking text + +@dfn{Killing} text means to delete the text from the line, but to save +it away for later use, usually by @dfn{yanking} (re-inserting) +it back into the line. +(`Cut' and `paste' are more recent jargon for `kill' and `yank'.) + +If the description for a command says that it `kills' text, then you can +be sure that you can get the text back in a different (or the same) +place later. + +When you use a kill command, the text is saved in a @dfn{kill-ring}. +Any number of consecutive kills save all of the killed text together, so +that when you yank it back, you get it all. The kill +ring is not line specific; the text that you killed on a previously +typed line is available to be yanked back later, when you are typing +another line. +@cindex kill ring + +Here is the list of commands for killing text. + +@table @kbd +@item C-k +Kill the text from the current cursor position to the end of the line. + +@item M-d +Kill from the cursor to the end of the current word, or, if between +words, to the end of the next word. +Word boundaries are the same as those used by @kbd{M-f}. + +@item M-@key{DEL} +Kill from the cursor the start of the current word, or, if between +words, to the start of the previous word. +Word boundaries are the same as those used by @kbd{M-b}. + +@item C-w +Kill from the cursor to the previous whitespace. This is different than +@kbd{M-@key{DEL}} because the word boundaries differ. + +@end table + +Here is how to @dfn{yank} the text back into the line. Yanking +means to copy the most-recently-killed text from the kill buffer. + +@table @kbd +@item C-y +Yank the most recently killed text back into the buffer at the cursor. + +@item M-y +Rotate the kill-ring, and yank the new top. You can only do this if +the prior command is @kbd{C-y} or @kbd{M-y}. +@end table + +@node Readline Arguments +@subsection Readline Arguments + +You can pass numeric arguments to Readline commands. Sometimes the +argument acts as a repeat count, other times it is the @i{sign} of the +argument that is significant. If you pass a negative argument to a +command which normally acts in a forward direction, that command will +act in a backward direction. For example, to kill text back to the +start of the line, you might type @samp{M-- C-k}. + +The general way to pass numeric arguments to a command is to type meta +digits before the command. If the first `digit' typed is a minus +sign (@samp{-}), then the sign of the argument will be negative. Once +you have typed one meta digit to get the argument started, you can type +the remainder of the digits, and then the command. For example, to give +the @kbd{C-d} command an argument of 10, you could type @samp{M-1 0 C-d}, +which will delete the next ten characters on the input line. + +@node Searching +@subsection Searching for Commands in the History + +Readline provides commands for searching through the command history +@ifset BashFeatures +(@pxref{Bash History Facilities}) +@end ifset +for lines containing a specified string. +There are two search modes: @dfn{incremental} and @dfn{non-incremental}. + +Incremental searches begin before the user has finished typing the +search string. +As each character of the search string is typed, Readline displays +the next entry from the history matching the string typed so far. +An incremental search requires only as many characters as needed to +find the desired history entry. +To search backward in the history for a particular string, type +@kbd{C-r}. Typing @kbd{C-s} searches forward through the history. +The characters present in the value of the @code{isearch-terminators} variable +are used to terminate an incremental search. +If that variable has not been assigned a value, the @key{ESC} and +@kbd{C-J} characters will terminate an incremental search. +@kbd{C-g} will abort an incremental search and restore the original line. +When the search is terminated, the history entry containing the +search string becomes the current line. + +To find other matching entries in the history list, type @kbd{C-r} or +@kbd{C-s} as appropriate. +This will search backward or forward in the history for the next +entry matching the search string typed so far. +Any other key sequence bound to a Readline command will terminate +the search and execute that command. +For instance, a @key{RET} will terminate the search and accept +the line, thereby executing the command from the history list. +A movement command will terminate the search, make the last line found +the current line, and begin editing. + +Readline remembers the last incremental search string. If two +@kbd{C-r}s are typed without any intervening characters defining a new +search string, any remembered search string is used. + +Non-incremental searches read the entire search string before starting +to search for matching history lines. The search string may be +typed by the user or be part of the contents of the current line. + +@node Readline Init File +@section Readline Init File +@cindex initialization file, readline + +Although the Readline library comes with a set of Emacs-like +keybindings installed by default, it is possible to use a different set +of keybindings. +Any user can customize programs that use Readline by putting +commands in an @dfn{inputrc} file, conventionally in his home directory. +The name of this +@ifset BashFeatures +file is taken from the value of the shell variable @env{INPUTRC}. If +@end ifset +@ifclear BashFeatures +file is taken from the value of the environment variable @env{INPUTRC}. If +@end ifclear +that variable is unset, the default is @file{~/.inputrc}. If that +file does not exist or cannot be read, the ultimate default is +@file{/etc/inputrc}. + +When a program which uses the Readline library starts up, the +init file is read, and the key bindings are set. + +In addition, the @code{C-x C-r} command re-reads this init file, thus +incorporating any changes that you might have made to it. + +@menu +* Readline Init File Syntax:: Syntax for the commands in the inputrc file. + +* Conditional Init Constructs:: Conditional key bindings in the inputrc file. + +* Sample Init File:: An example inputrc file. +@end menu + +@node Readline Init File Syntax +@subsection Readline Init File Syntax + +There are only a few basic constructs allowed in the +Readline init file.

If set to +@samp{visible}, Readline uses a visible bell if one is available. +If set to @samp{audible} (the default), Readline attempts to ring +the terminal's bell. + +@item bind-tty-special-chars +@vindex bind-tty-special-chars +If set to @samp{on}, Readline attempts to bind the control characters +treated specially by the kernel's terminal driver to their Readline +equivalents. + +@item comment-begin +@vindex comment-begin +The string to insert at the beginning of the line when the +@code{insert-comment} command is executed. The default value +is @code{"#"}. + +@item completion-ignore-case +If set to @samp{on}, Readline performs filename matching and completion +in a case-insensitive fashion. +The default value is @samp{off}. + +@item completion-prefix-display-length +@vindex completion-prefix-display-length +The length in characters of the common prefix of a list of possible +completions that is displayed without modification. When set to a +value greater than zero, common prefixes longer than this value are +replaced with an ellipsis when displaying possible completions. + +@item completion-query-items +@vindex completion-query-items +The number of possible completions that determines when the user is +asked whether the list of possibilities should be displayed. +If the number of possible completions is greater than this value, +Readline will ask the user whether or not he wishes to view +them; otherwise, they are simply listed. +This variable must be set to an integer value greater than or equal to 0. +A negative value means Readline should never ask. +The default limit is @code{100}. + +@item convert-meta +@vindex convert-meta +If set to @samp{on}, Readline will convert characters with the +eighth bit set to an @sc{ascii} key sequence by stripping the eighth +bit and prefixing an @key{ESC} character, converting them to a +meta-prefixed key sequence. The default value is @samp{on}. + +@item disable-completion +@vindex disable-completion +If set to @samp{On}, Readline will inhibit word completion. +Completion characters will be inserted into the line as if they had +been mapped to @code{self-insert}. The default is @samp{off}. + +@item editing-mode +@vindex editing-mode +The @code{editing-mode} variable controls which default set of +key bindings is used. By default, Readline starts up in Emacs editing +mode, where the keystrokes are most similar to Emacs. This variable can be +set to either @samp{emacs} or @samp{vi}. + +@item enable-keypad +@vindex enable-keypad +When set to @samp{on}, Readline will try to enable the application +keypad when it is called. Some systems need this to enable the +arrow keys. The default is @samp{off}. + +@item expand-tilde +@vindex expand-tilde +If set to @samp{on}, tilde expansion is performed when Readline +attempts word completion. The default is @samp{off}. + +@item history-preserve-point +@vindex history-preserve-point +If set to @samp{on}, the history code attempts to place the point (the +current cursor position) at the +same location on each history line retrieved with @code{previous-history} +or @code{next-history}. The default is @samp{off}. + +@item history-size +@vindex history-size +Set the maximum number of history entries saved in the history list. If +set to zero, the number of entries in the history list is not limited. + +@item horizontal-scroll-mode +@vindex horizontal-scroll-mode +This variable can be set to either @samp{on} or @samp{off}. Setting it +to @samp{on} means that the text of the lines being edited will scroll +horizontally on a single screen line when they are longer than the width +of the screen, instead of wrapping onto a new screen line. By default, +this variable is set to @samp{off}. + +@item input-meta +@vindex input-meta +@vindex meta-flag +If set to @samp{on}, Readline will enable eight-bit input (it +will not clear the eighth bit in the characters it reads), +regardless of what the terminal claims it can support. The +default value is @samp{off}. The name @code{meta-flag} is a +synonym for this variable. + +@item isearch-terminators +@vindex isearch-terminators +The string of characters that should terminate an incremental search without +subsequently executing the character as a command (@pxref{Searching}). +If this variable has not been given a value, the characters @key{ESC} and +@kbd{C-J} will terminate an incremental search. + +@item keymap +@vindex keymap +Sets Readline's idea of the current keymap for key binding commands. +Acceptable @code{keymap} names are +@code{emacs}, +@code{emacs-standard}, +@code{emacs-meta}, +@code{emacs-ctlx}, +@code{vi}, +@code{vi-move}, +@code{vi-command}, and +@code{vi-insert}. +@code{vi} is equivalent to @code{vi-command}; @code{emacs} is +equivalent to @code{emacs-standard}. The default value is @code{emacs}. +The value of the @code{editing-mode} variable also affects the +default keymap. + +@item mark-directories +If set to @samp{on}, completed directory names have a slash +appended. The default is @samp{on}. + +@item mark-modified-lines +@vindex mark-modified-lines +This variable, when set to @samp{on}, causes Readline to display an +asterisk (@samp{*}) at the start of history lines which have been modified. +This variable is @samp{off} by default. + +@item mark-symlinked-directories +@vindex mark-symlinked-directories +If set to @samp{on}, completed names which are symbolic links +to directories have a slash appended (subject to the value of +@code{mark-directories}). +The default is @samp{off}. + +@item match-hidden-files +@vindex match-hidden-files +This variable, when set to @samp{on}, causes Readline to match files whose +names begin with a @samp{.} (hidden files) when performing filename +completion, unless the leading @samp{.} is +supplied by the user in the filename to be completed. +This variable is @samp{on} by default. + +@item output-meta +@vindex output-meta +If set to @samp{on}, Readline will display characters with the +eighth bit set directly rather than as a meta-prefixed escape +sequence. The default is @samp{off}. + +@item page-completions +@vindex page-completions +If set to @samp{on}, Readline uses an internal @code{more}-like pager +to display a screenful of possible completions at a time. +This variable is @samp{on} by default. + +@item print-completions-horizontally +If set to @samp{on}, Readline will display completions with matches +sorted horizontally in alphabetical order, rather than down the screen. +The default is @samp{off}. + +@item revert-all-at-newline +@vindex revert-all-at-newline +If set to @samp{on}, Readline will undo all changes to history lines +before returning when @code{accept-line} is executed. By default, +history lines may be modified and retain individual undo lists across +calls to @code{readline}. The default is @samp{off}. + +@item show-all-if-ambiguous +@vindex show-all-if-ambiguous +This alters the default behavior of the completion functions. If +set to @samp{on}, +words which have more than one possible completion cause the +matches to be listed immediately instead of ringing the bell. +The default value is @samp{off}. + +@item show-all-if-unmodified +@vindex show-all-if-unmodified +This alters the default behavior of the completion functions in +a fashion similar to @var{show-all-if-ambiguous}. +If set to @samp{on}, +words which have more than one possible completion without any +possible partial completion (the possible completions don't share +a common prefix) cause the matches to be listed immediately instead +of ringing the bell. +The default value is @samp{off}. + +@item visible-stats +@vindex visible-stats +If set to @samp{on}, a character denoting a file's type +is appended to the filename when listing possible +completions. The default is @samp{off}. + +@end table + +@item Key Bindings +The syntax for controlling key bindings in the init file is +simple. First you need to find the name of the command that you +want to change. The following sections contain tables of the command +name, the default keybinding, if any, and a short description of what +the command does. + +Once you know the name of the command, simply place on a line +in the init file the name of the key +you wish to bind the command to, a colon, and then the name of the +command. +There can be no space between the key name and the colon -- that will be +interpreted as part of the key name. +The name of the key can be expressed in different ways, depending on +what you find most comfortable. + +In addition to command names, readline allows keys to be bound +to a string that is inserted when the key is pressed (a @var{macro}). + +@ifset BashFeatures +The @w{@code{bind -p}} command displays Readline function names and +bindings in a format that can put directly into an initialization file. +@xref{Bash Builtins}. +@end ifset + +@table @asis +@item @w{@var{keyname}: @var{function-name} or @var{macro}} +@var{keyname} is the name of a key spelled out in English.

There are four parser directives used. + +@table @code +@item $if +The @code{$if} construct allows bindings to be made based on the +editing mode, the terminal being used, or the application using +Readline. The text of the test extends to the end of the line; +no characters are required to isolate it. + +@table @code +@item mode +The @code{mode=} form of the @code{$if} directive is used to test +whether Readline is in @code{emacs} or @code{vi} mode. +This may be used in conjunction +with the @samp{set keymap} command, for instance, to set bindings in +the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if +Readline is starting out in @code{emacs} mode. + +@item term +The @code{term=} form may be used to include terminal-specific +key bindings, perhaps to bind the key sequences output by the +terminal's function keys. The word on the right side of the +@samp{=} is tested against both the full name of the terminal and +the portion of the terminal name before the first @samp{-}.

a @samp{&} +in the pattern is replaced with the text of the word being completed. +A literal @samp{&} may be escaped with a backslash; the backslash +is removed before attempting a match. +Any completion that matches the pattern will be removed from the list. +A leading @samp{!} negates the pattern; in this case any completion +not matching the pattern will be removed. + +Finally, any prefix and suffix specified with the @option{-P} and @option{-S} +options are added to each member of the completion list, and the result is +returned to the Readline completion code as the list of possible +completions. + +If the previously-applied actions do not generate any matches, and the +@option{-o dirnames} option was supplied to @code{complete} when the +compspec was defined, directory name completion is attempted. + +If the @option{-o plusdirs} option was supplied to @code{complete} when +the compspec was defined, directory name completion is attempted and any +matches are added to the results of the other actions. + +By default, if a compspec is found, whatever it generates is returned to +the completion code as the full set of possible completions. +The default Bash completions are not attempted, and the Readline default +of filename completion is disabled. +If the @option{-o bashdefault} option was supplied to @code{complete} when +the compspec was defined, the default Bash completions are attempted +if the compspec generates no matches. +If the @option{-o default} option was supplied to @code{complete} when the +compspec was defined, Readline's default completion will be performed +if the compspec (and, if attempted, the default Bash completions) +generate no matches. + +When a compspec indicates that directory name completion is desired, +the programmable completion functions force Readline to append a slash +to completed names which are symbolic links to directories, subject to +the value of the @var{mark-directories} Readline variable, regardless +of the setting of the @var{mark-symlinked-directories} Readline variable. + +There is some support for dynamically modifying completions. This is +most useful when used in combination with a default completion specified +with @option{-D}. It's possible for shell functions executed as completion +handlers to indicate that completion should be retried by returning an +exit status of 124. If a shell function returns 124, and changes +the compspec associated with the command on which completion is being +attempted (supplied as the first argument when the function is executed), +programmable completion restarts from the beginning, with an +attempt to find a compspec for that command. This allows a set of +completions to be built dynamically as completion is attempted, rather than +being loaded all at once. + +For instance, assuming that there is a library of compspecs, each kept in a +file corresponding to the name of the command, the following default +completion function would load completions dynamically: + +_completion_loader() +{ + . "/etc/bash_completion.d/$1.sh" >/dev/null 2>&1 && return 124 +} +complete -D -F _completion_loader + +@node Programmable Completion Builtins +@section Programmable Completion Builtins +@cindex completion builtins + +Two builtin commands are available to manipulate the programmable completion +facilities. + +@table @code +@item compgen +@btindex compgen +@example +@code{compgen [@var{option}] [@var{word}]} +@end example + +Generate possible completion matches for @var{word} according to +the @var{option}s, which may be any option accepted by the +@code{complete} +builtin with the exception of @option{-p} and @option{-r}, and write +the matches to the standard output. +When using the @option{-F} or @option{-C} options, the various shell variables +set by the programmable completion facilities, while available, will not +have useful values. + +The matches will be generated in the same way as if the programmable +completion code had generated them directly from a completion specification +with the same flags. +If @var{word} is specified, only those completions matching @var{word} +will be displayed. + +The return value is true unless an invalid option is supplied, or no +matches were generated. + +@item complete +@btindex complete +@example +@code{complete [-abcdefgjksuv] [-o @var{comp-option}] [-DE] [-A @var{action}] [-G @var{globpat}] [-W @var{wordlist}] +[-F @var{function}] [-C @var{command}] [-X @var{filterpat}] +[-P @var{prefix}] [-S @var{suffix}] @var{name} [@var{name} @dots{}]} +@code{complete -pr [-DE] [@var{name} @dots{}]} +@end example + +Specify how arguments to each @var{name} should be completed. +If the @option{-p} option is supplied, or if no options are supplied, existing +completion specifications are printed in a way that allows them to be +reused as input. +The @option{-r} option removes a completion specification for +each @var{name}, or, if no @var{name}s are supplied, all +completion specifications. +The @option{-D} option indicates that the remaining options and actions should +apply to the ``default'' command completion; that is, completion attempted +on a command for which no completion has previously been defined. +The @option{-E} option indicates that the remaining options and actions should +apply to ``empty'' command completion; that is, completion attempted on a +blank line. + +The process of applying these completion specifications when word completion +is attempted is described above (@pxref{Programmable Completion}).
