Alias Command in Linux

I am sure you might feel irritated typing long Linux commands again and again. Linux alias allows you to create custom shortcut commands that internally runs your long command.

• Find Currently Defined Linux Aliases

• Create Linux Alias

Find Currently Defined Linux Aliases

To list all the currently defined aliases use below command

alias

Create Linux Alias

To create a shortcut command, simply type the alias and assign it

alias ShortCut="Full Command"

Let's create a shortcut command for sqlplus / as sysdba

alias sq="sqlplus / as sysdba"

Now when you type sq, it will actually execute sqlplus / as sysdba. To make this permanent, add it to .bashrc file.

vi ~/.bashrc

alias sq="sqlplus / as sysdba"            --> at at the end
