| | |
| | | # grep "*@*@" file_list Displays every line
| | | # grep "*\@*\@" file_list Displays every line
| |
| | How about:
| |
| | egrep '.*@.*@' file_list
| | or
| | awk '/.*@.*@/ { print }'file_list
| |
| | Bob (who would use mawk 'cause it'd be fastest)

| When it comes to commands, JP goes by the shibboleth that
| 'shorter is better', so he'd scratch one each of ".", "*",
| " ", "{", " ", "p", "r", "i", "n", "t", " ", "}" and just type:
|
| mawk '/@.*@/' file_list

More elegant . . . less informative to those less knowledgeable.

OTOH it does, in fact, inform (or remind) us of the subtleties
of AWK, which by default prints any matched line.
