completion when the double quote immediately follows another word

delimiter.

jjjj. Fixed a bug resulting in a use-after-free if two file descriptors share

the same input buffer.

kkkk. The error message resulting from ${x:?} and ${x?} now differs depending

on whether the variable is null or unset.

llll. In Posix mode, the shell exits if a variable assignment fails and precedes

an empty simple command (after expansion).

mmmm. Fixed a timing problem with SIGALRM that could cause the read builtin to

drop characters.

nnnn. Added code to deal with kill(2) failing to send the shell a fatal signal
|

due to Linux pid namespace peculiarities.

oooo. Fixed a bug that made \C-@ (NUL) unusable in key sequences used for
|
||||
`bind -x' commands.
|
||||
|
||||
pppp. Fixed a bug that could cause SIGINT recursion when running an external
|
||||
command in a trap the shell takes after a command exits due to SIGINT.
|
||||
|
||||
qqqq. Make sure the shell turns off job control before running the command-
|
||||
not-found handle, so the command doesn't try to manipulate process
|
||||
groups.
|
||||
|
||||
rrrr. Fixed a problem with timing process substitutions that caused the shell
|
||||
to print timing information for the calling command.
|
||||
|
||||
ssss. Fixed a bug that caused backquotes in a here-document delimiter to mark
|
||||
the delimiter as quoted (inhibiting expansion of the here-document
|
||||
contents).
|
||||
|
||||
tttt. Fixed several problems with 0x01 and 0x177 in case pattern lists and

conditional command pattern matches.

uuuu. Fixed a bug that could cause the pattern matching engine to not recognize
|

locale-specific character classes.
|

vvvv. The auto-configuration now tests for /dev/stdin and /dev/fd independently.

wwww. The `globstar' code now skips over symbolic links to directories,
|
||||
preventing them from being scanned twice.
|

xxxx. When running `bind -x' commands, bash now sets READLINE_POINT based on
|
||||
the number of characters in the readline line buffer, not the number of
|

bytes.

yyyy. Fixed a problem that could cause recursive trap evaluation of the RETURN

trap when using `eval return'.
|

zzzz. Fixed a bug with expanding 0x01 in an unquoted here-document.
|

aaaaa. The process substitution code now closes and unlinks FIFOs when the

process on the other side exits, in order to prevent SIGPIPE or
|

waiting until a FIFO opened for read has a writer.
|
||||
|
||||
bbbbb. Fixed a bug with recursive calls to the parser overwriting the token in
|
||||
an {id}>foo construct.
|
||||
|
||||
ccccc. After a Posix discussion, the pattern matching engine just skips over
|
||||
invalid character classes in bracket expressions, instead of matching
|
||||
them like individual characters in the expression.
|
||||
|
||||
ddddd. Fixed a posix-mode problem with variable scoping when creating variables
|

from assignment statements preceding special builtins.

eeeee. Fixed a bug that could cause patterns containing backslashes to not be
|

run through the pattern matching engine.

be `undone' if the file descriptor in the redirection was closed when
|

the redirection was initially processed.

the release of bash-4.4. As always, the manual page (doc/bash.1) is

|
||||
|
||||
1. New Features in Bash
|
||||
|
||||
a. The `wait' builtin can now wait for the last process substitution created.
|
||||
|
||||
b. There is an EPOCHSECONDS variable, which expands to the time in seconds
|
||||
since the Unix epoch.
|
||||
|
||||
c. There is an EPOCHREALTIME variable, which expands to the time in seconds
|
||||
since the Unix epoch with microsecond granularity.
|
||||
|
||||
d. New loadable builtins: rm, stat, fdflags.
|
||||
|
||||
e. BASH_ARGV0: a new variable that expands to $0 and sets $0 on assignment.
|
||||
|
||||
f. When supplied a numeric argument, the shell-expand-line bindable readline
|
||||
command does not perform quote removal and suppresses command and process
|
||||
substitution.
|
||||
|
||||
g. `history -d' understands negative arguments: negative arguments offset from
|
||||
the end of the history list.
|
||||
|
||||
h. The `name' argument to the `coproc' reserved word now undergoes word
|
||||
expansion, so unique coprocs can be created in loops.
|
||||
|
||||
i. A nameref name resolution loop in a function now resolves to a variable by
|
||||
that name in the global scope.
|
||||
|
||||
j. The `wait' builtin now has a `-f' option, which signfies to wait until the
|
||||
specified job or process terminates, instead of waiting until it changes
|
||||
state.
|
||||
|
||||
k. There is a define in config-top.h that allows the shell to use a static
|
||||
value for $PATH, overriding whatever is in the environment at startup, for
|
||||
use by the restricted shell.
|
||||
|
||||
l. Process substitution does not inherit the `v' option, like command
|
||||
substitution.
|
||||
|
||||
m. If a non-interactive shell with job control enabled detects that a foreground
|
||||
job died due to SIGINT, it acts as if it received the SIGINT.
|
||||
|
||||
n. The SIGCHLD trap is run once for each exiting child process even if job
|
||||
control is not enabled when the shell is in Posix mode.
|
||||
|
||||
o. A new shopt option: localvar_inherit; if set, a local variable inherits the
|
||||
value of a variable with the same name at the nearest preceding scope.
|
||||
|
||||
p. `bind -r' now checks whether a key sequence is bound before binding it to
|
||||
NULL, to avoid creating keymaps for a multi-key sequence.
|
||||
|
||||
q. A numeric argument to the line editing `operate-and-get-next' command
|
||||
specifies which history entry to use.
|
||||
|
||||
r. The positional parameters are now assigned before running the shell startup
|
||||
files, so startup files can use $@.
|
||||
|
||||
s. There is a compile-time option that forces the shell to disable the check
|
||||
for an inherited OLDPWD being a directory.
|
||||
|
||||
t. The `history' builtin can now delete ranges of history entries using
|
||||
`-d start-end'.
|
||||
|
||||
u. The `vi-edit-and-execute-command' bindable readline command now puts readline
|
||||
back in vi insertion mode after executing commands from the edited file.
|
||||
|
||||
v. The command completion code now matches aliases and shell function names
|
||||
case-insensitively if the readline completion-ignore-case variable is set.
|
||||
|
||||
w. There is a new `assoc_expand_once' shell option that attempts to expand
|
||||
associative array subscripts only once.
|
||||
|
||||
x. The shell only sets up BASH_ARGV and BASH_ARGC at startup if extended
|
||||
debugging mode is active. The old behavior of unconditionally setting them
|
||||
is available as part of the shell compatibility options.
|
||||
|
||||
y. The `umask' builtin now allows modes and masks greater than octal 777.
|
||||

||||

|
||||

|
||||

|
||||
|
||||
2. New Features in Readline
|
||||
|
||||
a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
|
||||
Posix specifies (uses fnmatch(3) if available).
|
||||
|
||||
b. There are new `next-screen-line' and `previous-screen-line' bindable
|
||||
commands, which move the cursor to the same column in the next, or previous,
|
||||
physical line, respectively.
|
||||
|
||||
c. There are default key bindings for control-arrow-key key combinations.
|
||||
|
||||
d. A negative argument (-N) to `quoted-insert' means to insert the next N
|
||||
characters using quoted-insert.
|
||||
|
||||
e. New public function: rl_check_signals(), which allows applications to
|
||||
respond to signals that readline catches while waiting for input using
|
||||
a custom read function.
|
||||
|
||||
f. There is new support for conditionally testing the readline version in an
|
||||
inputrc file, with a full set of arithmetic comparison operators available.
|
||||
|
||||
g. There is a simple variable comparison facility available for use within an
|
||||
inputrc file. Allowable operators are equality and inequality; string
|
||||
variables may be compared to a value; boolean variables must be compared to
|
||||
either `on' or `off'; variable names are separated from the operator by
|
||||
whitespace.
