If you are familiar with the regular expressions that grep/egrep/fgrep/sed/awk
use, then you already know a good chunk of Perl's REs.  Perl adds quite a bit
to it.

And you don't have to know every little detail in order for it to be
useful.  I know of the top of my head maybe 55-60% of what REs can do
in Perl, and I get by pretty nice.  I have to look up something once
in a while, but that's no crime.

Regular expressions are also useful in Python 
(see the 're', 'regex', 'regsub' modules), and even Java (if you
have the com.oroinc.OroMatcher libraries, which are wonderful
(even though Oro, Inc. the company died years ago).
