Hello :)

I don't use perl when a shell script will do.

Sometimes the best way to keep things simple is to use total overkill. If I can do all my work in Perl, then anyone who needs to maintain it (including me) only needs to know one language. I can also increase the time I can spend on fine-tuning my Perl skills (including time spent coding in Perl) if I don't have to write/learn more shell script.

The most specialized/smallest tool isn't always the best for a job. Especially when you consider how projects have a strange way of growing beyond their original specifications. Just something to consider.
