# You need to install the command git-subtree from here:
# https://github.com/apenwarr/git-subtree

# Let's say you got a subdirectory 'lib-abc' under 'project' git repo that you like to
# split into a new repository

# First you need to create a bare repository, i.e. a Github project called 'lib-abc'
# Your new remote could be somethings like '[email protected]:yourname/lib-abc.git'

# 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
