Description Phil Battaglia 2005-06-03 16:43:45 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; Q312461; .NET CLR 1.1.4322)

Description of problem:
Using grep-2.5.1-24.4.i386.rpm, the "-w" option seems to fail consistently, by ignoring the "-o" option and adds an extra newline.  My usage includes the "-f" option to use for pattern matching.

grep-2.5.1-24.1.i386.rpm is successful.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create the pattern file.
2. Use egrep with the "-o" and "-w" options, as well as "-f <pattern file>".
3. Failure.

Actual Results:  *** Contents of pat_grep ***
[root@dev bin]# cat pat_grep

*** Using grep-2.5.1-24.4.i386.rpm ***
[root@dev bin]# echo " test" | egrep -m1 -wof pat_grep test


Expected Results:  *** Using grep-2.5.1-24.1.i386.rpm ***
[root@dev bin]# echo " test" | egrep -m1 -wof pat_grep

Confirmed.  Red Hat Enterprise Linux 4 is not affected.

This is a regression since Red Hat Enterprise Linux 3 release.
