Grep. Sed. Awk.
After using a greater number of invocations of them in a single shellscript, I became aware of this new, budding language called Perl. Best glue language I'd seen.
Over the years, I kept using this blossoming language, especially for quick reporting.
It's still my favorite language, and it has matured to include a great many features never conceived of in the beginning. I still write one-liners with it, and some of those are sometimes humorous.
"Perl. There is no substitute."
