I sometimes wonder why we don't see ruby used for shell stuff more often. It inherited most of the good stuff for shell scripting from Perl, and Perl took a lot of it's syntax from sh and sed and awk, so almost anything you can do in shell script you can do in ruby, but with an option of making it gradually less terse and more readable, while having sane variables and data handling from the start.

Also ruby is great in allowing complexity to grow smoothly, no sudden hiccups. You start with just one line (everything goes into module main implicitly), extend it to a single-file script, require some built-in libraries, then add a module or helper class in the same file, and only then maybe extract those files to required files, add gems, whatever. No boilerplate whatsoever, no jumps, no big rewrites.

meanwhile, a lot of tooling nowadays is written in Go, and I have no idea why, it's not friendly for os manipulation at all, and number crunching power is not needed in many, many tasks of that sort.
