I’ve been working with the PERL on a few projects. The power of PERL comes from two things. The First and most important is it’s Regular Expressions, which are very powerful pattern matching.
This is very useful for processing a long log file, looking for oddities, or when converting data from one file format to another.
PERL is also Interperted, so you can make changes to your program and test them immediately.
I downloaded a copy of PERL from ActiveState.com
