I'm going to put Ruby under this one, as well. Ruby inherited a ton of Perlisms that make it competitive with Perl, awk, and sed for these types of use cases. But they're really underused Eg the following flags are all relevant here: n, p, e, i, l, a, s, 0, c, F, and the 2-letter globals ruby -e 'puts global_variables.grep /\$.$/' and BEGIN { ... } and END { ... } and ARGF and flip flops (which most people don't even know exist), and regex literals in conditionals, and the private methods that are added to main when -n and -p flags are set. IDK, probably other stuff, too, that's all off the top of my head.

We're a place where coders share, stay up-to-date and grow their careers.
