Using a bash alias can save a lot of typing or having to copy and paste commands that you use all the time. Some people also use scripts, I’m not one of those. All you have to do is add to your .bashrc file in the Home directory, or if you’re using a flavor of Ubuntu, you have the option to put them in .bash-aliases. Aliases are pretty easy to setup, just use the alias name='value' format.

Here is a list of my bash aliases that I use quite often, modify to suit your needs and add to the bottom of the respected file:
