in PR 31895.
Patch changes unknown.
Mainstream changes between 2.0 and 2.4.2:
Version 2.4.2
- Added more check in configure to default the grep-${version}/src/regex.c
instead of the one in GNU Lib C.
Version 2.4.1
- If the final byte of an input file is not a newline, grep now silently
supplies one.
- The new option --binary-files=TYPE makes grep assume that a binary input
file is of type TYPE.
--binary-files='binary' (the default) outputs a 1-line summary of matches.
--binary-files='without-match' assumes binary files do not match.
--binary-files='text' treats binary files as text
(equivalent to the -a or --text option).
- New option -I; equivalent to --binary-files='without-match'.
Version 2.4:
- egrep is now equivalent to `grep -E' as required by POSIX,
removing a longstanding source of confusion and incompatibility.
`grep' is now more forgiving about stray `{'s, for backward
compatibility with traditional egrep.
- The lower bound of an interval is not optional.
You must use an explicit zero, e.g. `x{0,10}' instead of `x{,10}'.
(The old documentation incorrectly claimed that it was optional.)
- The --revert-match option has been renamed to --invert-match.
- The --fixed-regexp option has been renamed to --fixed-string.
- New option -H or --with-filename.
- New option --mmap. By default, GNU grep now uses read instead of mmap.
This is faster on some hosts, and is safer on all.
- The new option -z or --null-data causes `grep' to treat a zero byte
(the ASCII NUL character) as a line terminator in input data, and
to treat newlines as ordinary data.
- The new option -Z or --null causes `grep' to output a zero byte
instead of the normal separator after a file name.
- These two options can be used with commands like `find -print0',
`perl -0', `sort -z', and `xargs -0' to process arbitrary file names,
even those that contain newlines.
- The environment variable GREP_OPTIONS specifies default options;
e.g. GREP_OPTIONS='--directories=skip' reestablishes grep 2.1's
behavior of silently skipping directories.
- You can specify a matcher multiple times without error, e.g.
`grep -E -E' or `fgrep -F'. It is still an error to specify
conflicting matchers.
- -u and -U are now allowed on non-DOS hosts, and have no effect.
- Modifications of the tests scripts to go around the "Broken Pipe"
errors from bash. See Bash FAQ.
- New option -r or --recursive or --directories=recurse.
(This option was also in grep 2.3, but wasn't announced here.)
- --without-included-regex disable, was causing bogus reports .i.e
doing more harm then good.
Version 2.3:
- When searching a binary file FOO, grep now just reports
`Binary file FOO matches' instead of outputting binary data.
This is typically more useful than the old behavior,
and it is also more consistent with other utilities like `diff'.
A file is considered to be binary if it contains a NUL (i.e. zero) byte.
The new -a or --text option causes `grep' to assume that all
input is text. (This option has the same meaning as with `diff'.)
Use it if you want binary data in your output.
- `grep' now searches directories just like ordinary files; it no longer
silently skips directories. This is the traditional behavior of
Unix text utilities (in particular, of traditional `grep').
Hence `grep PATTERN DIRECTORY' should report
`grep: DIRECTORY: Is a directory' on hosts where the operating system
does not permit programs to read directories directly, and
`grep: DIRECTORY: Binary file matches' (or nothing) otherwise.
The new -d ACTION or --directories=ACTION option affects directory handling.
`-d skip' causes `grep' to silently skip directories, as in grep 2.1;
`-d read' (the default) causes `grep' to read directories if possible,
as in earlier versions of grep.
- The MS-DOS and Microsoft Windows ports now behave identically to the
GNU and Unix ports with respect to binary files and directories.
Version 2.2:
Bug fix release.
- Status error number fix.
- Skipping directories removed.
- Many typos fix.
- -f /dev/null fix(not to consider as an empty pattern).
- Checks for wctype/wchar.
- -E was using the wrong matcher fix.
- bug in regex char class fix
- Fixes for DJGPP
Version 2.1:
This is a bug fix release(see Changelog) i.e. no new features.
- More compliance to GNU standard.
- Long options.
- Internationalisation.
- Use automake/autoconf.
- Directory hierarchy change.
- Sigvec with -e on Linux corrected.
- Sigvec with -f on Linux corrected.
- Sigvec with the mmap() corrected.
- Bug in kwset corrected.
- -q, -L and -l stop on first match.
- New and improve regex.[ch] from Ulrich Drepper.
- New and improve dfa.[ch] from Arnold Robbins.
- Prototypes for over zealous C compiler.
- Not scanning a file, if it's a directory
(cause problems on Sun).
- Ported to MS-DOS/MS-Windows with DJGPP tools.
See Changelog for the full story and proper credits.
