Newbie question: Calling a shell script from ruby

ruby-talk

Hi

Apologies if this question is already answered in the doc. How do I call a
shell script from within ruby code? I have a lot of existing scripts that
are written in perl and I’d like to call them from a ruby framework. I
haven’t found anything in the doc about this, maybe I missed something?

Regards

Zubin

shell script

Just like in a shell script. There’s more information in the Pickaxe.

A simple way is

system(“/some/where/foo.sh”)
