It seems file globbing as done by ‘grep --exclude’ is broken when wildcards are used.

 

$ echo foo >bar

$ grep --exclude='.*' . ./bar

$ grep --exclude='.*' . bar

foo

 

Expected behavior: grep –exclude should not exclude bar, whether it is prefixed by ./ or not. According to the man page:

“       --exclude=GLOB

              Skip files whose *base name* matches GLOB (using wildcard matching). […]”

 

This behavior seems to only occur with whenever a directory component of the file path matches the GLOB, e.g.:

$ grep --exclude '.*' . ../bar

$ grep --exclude '.*' . .../bar

$ grep --exclude '.*' . .TEST/bar

$ grep --exclude '.*' . hugues/.TEST/bar

 

The bug triggers with other globs, unless there is no wildcard:

$ grep --exclude 'w*' . work/bar

$ grep --exclude 'work' . work/bar

foo

 

Regards,

 

Hugues Andreux

Thanks, I think that's a bug in the documentation, not in the code; grep's behavior is similar to that of tar's, which has similar options. I installed the attached documentation patch.
