# 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

Filter json file with jq

Let's say we have the file data.json with a json compacted in one line:

$ cat data.json
{"employees":[{"name":"Shyam","email":"shyamjaiswal@example.com"},{"name":"Bob","email":"bob32@example.com"},{"name":"Jai","email":"jai87@example.com"}]}

We can use the command jq to see it in with nicer format:

# This is a small test to check how to pass some parameters with
# special characters (!) to avoid shell calls, to ansible-playbook.

_except='!dell10,!dell19'

ansible-playbook -l "${_except}" bootstrap.yml
