This is GNU grep, the "fastest grep in the west" (we hope). All
|
|
bugs reported in previous releases have been fixed. Many exciting new
|
|
bugs have probably been introduced in this revision.
|
|
|
|
GNU grep is provided "as is" with no warranty. The exact terms
|
|
under which you may use and (re)distribute this program are detailed
|
|
in the GNU General Public License, in the file COPYING.
|
|
|
|
GNU grep is based on a fast lazy-state deterministic matcher (about
|
|
twice as fast as stock Unix egrep) hybridized with a Boyer-Moore-Gosper
|
|
search for a fixed string that eliminates impossible text from being
|
|
considered by the full regexp matcher without necessarily having to
|
|
look at every character. The result is typically many times faster
|
|
than Unix grep or egrep. (Regular expressions containing back-references
|
|
will run more slowly, however.)

KNOWN BUGS:
|
|
|
|
Several tests in fmbtest.sh and foad1.sh fail under the cs_CZ.UTF-8 locale
|
|
and have been disabled.
|
|
|
|
The combination of -o and -i options is broken and the known failing cases
|
|
are disabled in foad1.sh
|
|
|
|
The option -i does not work properly in some multibyte locales such as
|
|
tr_TR.UTF-8 where the upper case and lower case forms of a character are not
|
|
necessarily of the same byte length.
