1 This is GNU grep, the "fastest grep in the west" (we hope). All bugs reported
|
|
al@19222
|
2 in previous releases have been fixed. Many exciting new bugs have probably been
|
|
al@19222
|
3 introduced in this revision.

5 GNU grep is provided "as is" with no warranty. The exact terms under which you
|

9 GNU grep is based on a fast lazy-state deterministic matcher (about twice as
|
|
al@19222
|
10 fast as stock Unix egrep) hybridized with a Boyer-Moore-Gosper search for a
|
|
al@19222
|
11 fixed string that eliminates impossible text from being considered by the full
|
|
al@19222
|
12 regexp matcher without necessarily having to look at every character. The
|
|
al@19222
|
13 result is typically many times faster than Unix grep or egrep. (Regular
|
|
al@19222
|
14 expressions containing backreferencing will run more slowly, however.)

19 KNOWN BUGS:
|
|
al@19222
|
20
|
|
al@19222
|
21 Several tests in fmbtest.sh and foad1.sh fail under the cs_CZ.UTF-8 locale
|
|
al@19222
|
22 and have been disabled.
|
|
al@19222
|
23
|
|
al@19222
|
24 The combination of -o and -i options is broken and the known failing cases
|
|
al@19222
|
25 are disabled in foad1.sh
|
|
al@19222
|
26
|
|
al@19222
|
27 The option -i does not work properly in some multibyte locales such as
|
|
al@19222
|
28 tr_TR.UTF-8 where the upper case and lower case forms of a character are not
|
|
al@19222
|
29 necessarily of the same byte length.
