Yep, ruby is a natural, pipeline friendly, command line companion out of the box. https://github.com/learnbyexample/Command-line-text-processi... https://learnbyexample.github.io/learn_ruby_oneliners/

Nice! A few suggestions if I may: * please consider using the same prompt for all examples, a few of them start with `code` while some others start with `awk book` and some do not have any prompt at all * split long chapters into smaller…

Just for anyone else, you could probably end up in a similar corner with perl - but in both cases it's likely a case of "holding it wrong" - ruby borrows heavily from perl which borrowed heavily from shell with sed, awk, grep, cut and…

I have a repo dedicated for some of the cli text processing tools like grep/sed/awk/perl/sort/etc. Here's my one-liner collection for awk [1] [1] https://github.com/learnbyexample/Command-line-text-processi...

comment by asicsp · 2020-01-22 · in Why Learn Awk? (2016)

Perl's problem is that it's more confusing than it is powerful. I think most of the people who were into Perl for the "beauty" ended up going to ruby. People who were into it for CPAN went to python. You might find this interesting, as you…

I made a compilation of Ruby one-liners [1] as well last year. There's plenty of stuff that is similar to Perl, which in turn had borrowed from awk, sed and other tools. The biggest difference I'd pick is Perl's context based operation. #…

I'd say it is more similar to perl than awk for options like -F -l -a -n -e -0 etc. And perl borrowed stuff from sed, awk, etc I have a collection for ruby one-liners too [1] [1] https://github.com/learnbyexample/Command-line-text-processi.…

I haven't tried it yet, but it would depend on what sort of features you need Python wouldn't be a good choice for cli usage Perl is awesome to use from cli, and it is not just simple search and replace, see my tutorial[1] if you want to…

one-liners are fun though, especially if you like code golfing.. if you're interested, you could give my tutorial( https://github.com/learnbyexample/Command-line-text-processi... ) a try it has over 300 examples..
