GNU/Linux Command – ALIAS

alias – Create alias name for a command.

‘alias’ is Bash build-in command. This is very useful to create a simple alias for a complex/ long/frequent commands. Once alias created, you can use the alias to call the original command. This alias are deleted after closing the shell session. For the next session, you have to create it again. So to avoid this problem, you have to add the alias creation commands in your .bashrc file.
$ alias -- Prints all alias commands  $ alias cls=clear -- Alias for new user from DOS world.  $ alias ls="ls -F --color=always" -- Alias long ls command.  $ alias mycd='cd a/b/c/d/e/f/h' -- Shortcut for long CD.  $ alias ls -- Print the alias' original command.  $ ls -- Skip alias and run the original command.
