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 backreferencing
|
||
|
|
will run more slowly, however.)
