Enable “ll” command in ubuntu

This might be known to many *nix gurus, but it was new to me. Many systems come with the ll command that is a shortcut for ‘ls -al’.

To activate this in ubuntu, modify your ~/.bashrc file and uncomment the alias command settings

alias ll=’ls -l’

There are other options available. Now all you have to do is type ll and you get the equivalent of ‘ls-al’!
