I think this is an easier way to do it:

add this to a file called .bash_aliases instead (it should be a file right next to .bashrc, if not just create it)

You can add aliases to .bashrc with this, but I personally perfer to have aliases in their own file

Another thing, if you have a console window open while adding it, restart it so that the console is aware of the aliases. Alternatively, google something like “sourcing bashrc” or “sourcing aliases” and apply the commands you find

If you wish to add aliases to a bash script (for later automation), you add these two lines

shopt -s expand_aliases

source ~/.bash_aliases

but of course add this to the top of your bash scripts, so that your script knows to use the bash shell:

#!/bin/bash
