Hi,

Today I was reading making Script that runs as soon as user logs in to their linux box. During this research I found one interesting thing…

Command alias, In my words short cut to the existing big command is called Command Alias.
If you have used Fedore Core you may have used “ll” command to simulate “ls -l” now ll is an alias command for ls -l.

For example I want the Same ll command in my CentOs. I edit User Start up script for root found in /etc/.bashrc and put this line

alias ll=’ls -l’ there and now when I login as root user I get “ll” command
