Hello gnu hackers
I am seeing a problem when trying to extract the matching string and
anchoring to the beginning of the string. Using 2.5.1 on Redhat EL4
address@hidden log]$ echo 'abac' | grep -o '^a.'
ab
ac
This should, IMO, only return "ab", since ac does not match at the
beginning of the link.
Also, if -o is supposed to return multiple occurrences from the same
line, I believe this should be documented. For instance:
-o, --only-matching
Show only the part of a matching line that matches PATTERN. If multiple
non-overlapping matches are found in the same line, a match is reported
for each.
I believe that this functionality should be disabled by default, but
would be a very nice option.
