Thanks for the shout out for my Ruby one-liners ebook. The second link (https://learnbyexample.github.io/learn_ruby_oneliners/) is the latest version.

Does ruby come standard on most distros (Eg mainly thinking of RHEL-based here), or you’d have to install it usually?

[freedomben]

Usually not, although it's one of the top/main packages supported by Red Hat. `dnf install ruby` will work everywhere.

Don't know about RHEL and I'm not aware of Linux distros that come with Ruby pre-installed. Perl/Python are usually available by default.

Suse/openSuse comes with Ruby pre-installed because Yast, their distinctive system manager tool, is written in Ruby.
