Sometimes typing commands can get really repetitive, or if you need to type a long command many times, it’s best to have an alias you can use for that. To create an alias for a command you simply specify an alias name and set it to the command.
$ alias foobar='ls -la'
Now instead of typing ls -la, you can type foobar and it will execute that command, pretty neat stuff. Keep in mind that this command won't save your alias after reboot, so you'll need to add a permanent alias in:
or similar files if you want to have it persist after reboot.
You can remove aliases with the unalias command:
$ unalias foobar
Create a couple of aliases then remove them.
