The alias And unalias Commands Explained With Examples
You may forget the complex and lengthy Linux commands after certain period of time unless you’re a heavy command line user. Sure, there are a few ways to recall the forgotten commands. You could simply save the frequently used commands and use them on demand. Also, you can bookmark the important commands in your Terminal and use whenever you want. And, of course there is already a built-in “history” command available to help you to remember the commands.
