The source has been reorganized: nearly all extern function + declarations have been moved to header files, function prototypes + have been added to most header files, function declarations have + been moved to file scope, dead code has been removed, the + bash history code has been isolated in bashhist.[ch], and several + new header files have been created + +b. `set -o posix' puts bash into Posix.2 mode + +c. If $POSIX_PEDANTIC exists in the initial environment or is assigned + a value, bash enters Posix.2 mode + +d. Bash sets $OSTYPE to a string describing the UNIX version + +e. The features.info file was completely rewritten and now reflects + the current state of things + +f. A manual page for readline is in documentation/readline.{3,ps} + +g. The test builtin emulates /dev/fd/x for systems without /dev/fd + +h. `dirs' has -n and +n options to access members of the directory stack + +i. Prompt string expansion handles invisible characters in the prompt; + \[ and \] are used (and required) to start and end sequences of + invisible chars + +j. NO_PROMPT_VARS has been removed + +k. New machine descriptions have been added: IBM AIX/ESA, NEC EWS, NetBSD, + FreeBSD, QNX 4.2, concurrent, MIPS SVR4.2, Lynx 2.1 + +l. RESTRICTED_SHELL is no longer defined by default in config.h + +m. The version string in $BASH_VERSION has changed to dist.patch(build) + +n. $history_control has been renamed to $HISTCONTROL and now takes the + value `ignoreboth' ($history_control is still accepted for backwards + compatibility) + +o. There is a new program `bashbug' for reporting bugs. Eventually I will + probably switch to gnats. + +p. auto_resume can take the values `exact' and `substring' + +q. `set -P' (`set -o physical') enables the same physical view of the + file system that `nolinks' enables (`nolinks' will remain for one + more release) + +r. There is a `mkmachtype' program to generate a GNU-style machine type + string (e.g., `sparc-sun-sunos4.1.2') suitable for assigning to + $MACHTYPE + +s. The variable $HISTCMD returns the current history number + +t. Variables in directory names are now expanded while doing completion + +u. The test suite has been expanded and is runnable as a regression test + with `make tests' + +v. `bye' is no longer a builtin synonym for `exit' + +w. The ksh `select' control construct has been implemented + +x. The `ignoreeof' attribute can be inherited if $IGNOREEOF is exported + +y. The `USG-style' echo is now a configuration option. Define + DEFAULT_ECHO_TO_USG for default \-interpretation without the -e flag + +z. There is a copy of an article I wrote about bash for the Linux + Journal in documentation/article.{ms,ps} + +aa. The `pwd' builtin now obeys the setting of `set -o physical' (`nolinks') + +bb. Process substitution is no longer performed when the shell is in + `posix mode' + +cc. Users may change the debugging and optimization flags to cc by specifying + CFLAGS to make + +2. New Features in Readline + +a. Readline now understands sequences of invisible characters in the prompt + string, as long as they are escaped (e.g., by the bash \[ and \] escapes) + +b. A `set keymap' variable assignment + +c. A `bell-style' variable that can be set to `visible', `audio', or `none' + +d. A `show-all-if-ambiguous' variable, which causes non-unique completion + to immediately list the possible completions + +e. An `output-meta' variable to make readline directly output chars + with the eighth bit set + +f. New bindable readline commands: kill-whole-line, tilde-expand, + vi-redo, vi-tilde-expand, emacs-editing-mode, + non-incremental-forward-search-history-again, + non-incremental-reverse-search-history-again + +g. New history-search-forward and history-search-backward to search for + the characters between the start of the current line and point + +h. Readline takes the name of the startup file from the INPUTRC variable + before defaulting to ~/.inputrc + +i. isearch no longer finds identical lines multiple times in succession + +j. M-C-H bound to backward-kill-word in emacs mode + +k. M-~ bound to tilde-expand in emacs mode + +l. History expansion is now fully csh-compatible: missing modifiers and + substitutions have been added, and bugs fixed + +m. When asking whether or not to display the possible completions, readline + now accepts space as equivalent to `y' and rubout for `n' + +n. Readline now attempts to find and bind the arrow keys into the vi mode + movement keymap + +3. Bugs fixed in Bash + +a. Portability fixes: `index' and `rindex' are gone completely, many + OS-specific defines have been replaced with feature-test macros, + the use of alloca has been reduced, and other platform-specific fixes + (e.g. cray) have been made + +b. The man page has been fixed up and brought up to date + +c. Speed improvements: here documents, variable expansion, history + expansion, command substitution + +d. If history is stifled, the history list replaces the history file at + exit + +e. Asynchronous jobs re-run with fc -s now print the job number + +f. Output redirections do not perform filename expansion in Posix.2 mode + when the shell is not interactive + +g. operate_and_get_next now works on the most recent line even if the + history is unstifled + +h. $PROMPT_COMMAND execution no longer causes recursive invocations + of yyparse() + +i. An error message is printed if job control initialization fails + +j. A command found in $PATH from the temporary environment is not hashed + +k. Errors display the name of the script if the shell is not interactive + +l. Fixed expression evaluation so blank expressions return 0 + +m. Fixed a bug that caused SIGINT and SIGQUIT not to be ignored in some + asynchronous children + +n. Pipes used for /dev/fd process substitution are now closed on errors + +o. Fixed /dev/null redirection so that ( list ) subshells inherit the + `stdin-has-been-redirected' flag as in sh + +p. Process substitution now works only when unquoted + +q. Fixed a bug where the async flag was added inappropriately in a command + like `a;b;c;d &' + +r. Fixed off-by-one bug which caused negative history offsets in `fc' to + be wrong + +s. Shell now remembers mail dates at startup on all systems + +t. Posix systems without job control no longer create so many zombies + +u. $ENV is now sourced by shells forked to execute scripts without a + leading `#!' line + +v. Non-root users can now use the `unlimited' argument to ulimit and have + the resource value set to the hard limit + +w. Made bash more sh-compatible by assigning the first argument after + `-c command' to $0 + +x. Fixed mail checking bug to note that *new* mail has arrived + +y. Fixed off-by-one error in mailcheck.c:free_mail_files() + +z. Fixed a bug where command strings passed to `bash -c' would be truncated + after executing the first disk command in the string + +aa. Fixed a bug which caused redirections passed to executable commands with + input or output pipes to be closed before the command was executed + +bb. Fixed a bug which caused bash to search for files supplied on the command + line in the $PATH if the initial open failed, even if the names contained + a slash + +cc. The initial argument parsing was fixed up so that other options can + be supplied with -c (that is, `sh -ec command' now works as make + intends), and so `bash -o' lists all the shell options at startup. + +dd. Error messages are consistently prefixed with the name of the shell + or shell script when non-interactive. + +ee. Fixed up a problem with the `read' builtin that occurred when more + variables than arguments were supplied. + +ff. Unset the variables passed to `read' as arguments when EOF is + read from stdin (sh, Posix.2 compatibility). + +gg. Fixes to the command printing code to make the output of `type' + available as legal shell input. + +ii. Fixes so that command completion is attempted after all of the shell + command separator characters. + +jj. Fixes to the shell completion code so that it handles quoted characters + and substrings better. + +kk. Bash no longer looks through $PATH for a shell script passed as an + argument if the name contains slashes. + +ll. Bash now checks that the `name' in a `name[=value]' argument to `declare' + (and thus `typeset', `export', and `readonly') is a legal shell variable + name. + +4. Bugs fixed in Readline + +a. The ^W and ^U bindings in non-incremental search mode have been changed + to be closer to what Posix specifies + +b. Tries to initialize the keypad to enable the arrow keys + +c. Multiple words are now killed and yanked in the right order + +d. rl_read_init_file now reads filenames in a more regular order: the last + one read, $INPUTRC, then ~/.inputrc + +e. yank_nth_arg inserts a space in the right place in vi mode + +f. Fixed a bug in the history library that tried to write to a file opened + O_RDONLY + +g. Binding of `0' in vi command mode is now right + +h. The VISIBLE_STATS completion listing code now follows symlinks + +i. Memory allocated with alloca() is no longer passed to other functions + +j. Error messages are now printed for unrecognized history modifiers + +k. Fixed a problem with history library and `!#'; now it is more csh-like. + +l. Fixed a csh incompatibility in the history library: now only an end of + line or `?' terminates a ?string history search string. + +m. Fixed a problem with readline completion that sometimes caused possible + matches to be listed one per line when `show-all-if-ambiguous' was set. + +n. Fixed a problem in the readline display code that caused divide-by-zero + errors. + +o. Fixed an off-by-one error in the kill ring reallocation code. |
