Use Ruby as AWK or Grep
# A few examples about how to use Ruby for parsing files as we could do
# with Awk or Grep. This is based on what I learn fro this post:
# http://code.joejag.com/2009/using-ruby-as-an-awk-replacement/
# Split each line with ':' and print the first $F[0] field
awk -F: '{ print $1 }' /etc/passwd
ruby -F: -nae 'puts $F[0]' /etc/passwd
# Parse the 'ps aux' output
# It'll print the ID process for the 'jojeda' user
