No new features. - -Version 2.5 - - The new option --label allows to specify a different name for input - from stdin. See the man or info pages for details. - - - The internal lib/getopt* files are no longer used on systems providing - getopt functionality in their libc (e.g. glibc 2.2.x). - If you need the old getopt files, use --with-included-getopt. - - - The new option --only-matching (-o) will print only the part of matching - lines that matches the pattern. This is useful, for example, to extract - IP addresses from log files. - - - i18n bug fixed ([A-Z0-9] wouldn't match A in locales other than C on - systems using recent glibc builds - - - GNU grep can now be built with autoconf 2.52. - - - The new option --devices controls how grep handles device files. Its usage - is analogous to --directories. - - - The new option --line-buffered fflush on everyline. There is a noticeable - slow down when forcing line buffering. - - - Back references are now local to the regex. - grep -e '\(a\)\1' -e '\(b\)\1' - The last backref \1 in the second expression refer to \(b\) - - - The new option --include=PATTERN will only search matching files - when recursing in directories - - - The new option --exclude=PATTERN will skip matching files when - recursing in directories. - - - The new option --color will use the environment variable GREP_COLOR - (default is red) to highlight the matching string. - --color takes an optional argument specifying when to colorize a line: - --color=always, --color=tty, --color=never - - - The following changes are for POSIX.2 conformance: - - . The -q or --quiet or --silent option now causes grep to exit - with zero status when a input line is selected, even if an error - also occurs. - - . The -s or --no-messages option no longer affects the exit status. - - . Bracket regular expressions like [a-z] are now locale-dependent. - For example, many locales sort characters in dictionary order, - and in these locales the regular expression [a-d] is not - equivalent to [abcd]; it might be equivalent to [aBbCcDd], for - example. To obtain the traditional interpretation of bracket - expressions, you can use the C locale by setting the LC_ALL - environment variable to the value "C". - - - The -C or --context option now requires an argument, partly for - consistency, and partly because POSIX.2 recommends against - optional arguments. - - - The new -P or --perl-regexp option tells grep to interpert the pattern as - a Perl regular expression. - - - The new option --max-count=num makes grep stop reading a file after num - matching lines. - New option -m; equivalent to --max-count. - - - Translations for bg, ca, da, nb and tr have been added. - -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. - -Version 2.0: - -The most important user visible change is that egrep and fgrep have -disappeared as separate programs into the single grep program mandated -by POSIX 1003.2. New options -G, -E, and -F have been added, -selecting grep, egrep, and fgrep behavior respectively. For -compatibility with historical practice, hard links named egrep and -fgrep are also provided. See the manual page for details. - -In addition, the regular expression facilities described in Posix -draft 11.2 are now supported, except for internationalization features -related to locale-dependent collating sequence information. - -There is a new option, -L, which is like -l except it lists -files which don't contain matches. The reason this option was -added is because '-l -v' doesn't do what you expect. - -Performance has been improved; the amount of improvement is platform -dependent, but (for example) grep 2.0 typically runs at least 30% faster -than grep 1.6 on a DECstation using the MIPS compiler. Where possible, -grep now uses mmap() for file input; on a Sun 4 running SunOS 4.1 this -may cut system time by as much as half, for a total reduction in running -time by nearly 50%. On machines that don't use mmap(), the buffering -code has been rewritten to choose more favorable alignments and buffer -sizes for read(). - -Portability has been substantially cleaned up, and an automatic -configure script is now provided. - -The internals have changed in ways too numerous to mention. -People brave enough to reuse the DFA matcher in other programs -will now have their bravery amply "rewarded", for the interface -to that file has been completely changed. Some changes were -necessary to track the evolution of the regex package, and since -I was changing it anyway I decided to do a general cleanup. |
