I have a Perl script that takes an input and outputs a string. I would
like to call this Perl script from my Ruby script and have the string
appear in my Ruby script after.
I was thinking I would use the command line of my system as the middle
man. Looking at Ruby’s Kernel#system it only returns true or false if
the command is found and ran successfully or not. I would like to get
that string instead of true if possible.
I am hoping to avoid complicated things like having the Perl write to a
file and then read that file into Ruby.
