Sometime may happens you need to beautify xml or json from a bash script. So here there are two methods to easily obtaing a pretty print of your data:
Command to beautify XML
cat filename.xml | xmllint --format -
Command to beautify JSON
cat filename.json | python -m json.tool
In case you miss above tools on your system, they can be installed with
sudo apt-get install libxml2-utils sudo apt-get install python sudo pip install simplejson
Good luck!
