Hi Jose:

I'm going to be a bit of a radical here and suggest that since you are leanring regular expressions anyway, why not learn regular expressions on steroids - use Perl. Just as example, in basic RE to find whitespace you need to look for spaces, tabs, LF's, CR's, and
FF's explicitly. That's not hard, merely tedious. In Perl's re, all of that is simply \s or \S - non-whitespace. Man perlre for details. The nice thing about this approach is that you get the best of grep, awk, sed, and the shell rolled into one and this stuff will also port to Windows.

Food for thought, Clay

Jose,

I agree with Clay, that "perl" has the best pattern matching available in the free world.
