The cool thing about programming languages like Ruby is that they’re very conducive to one-liners. You can use them to generate bash statements that you can then pipe back to bash. `ls | ruby -nle 'puts "mv #{$_} #{$_.gsub(/_/, ".")}"' | bash` is a pattern I use all the time, for example. Easy way of generating complex bash statements without having to bother with the bash man page.
replyDo you need to pipe the ruby output to bash? Ruby could just run the mv directly by wrapping in backticks instead of quotes.
replySeems to be the flavour of the day :)
