Pearl cheatsheet

Perl should be installed on Mac OS using Brew

$ brew install perl

If perl is already installed, this will throw an error. You should then install perl with perlbrew. Perlbrew is a versions environment for Perl, such as rbenv for ruby and nvm for node. See a complete guide for perlbrew.
