In order to make a alias shortcut permanent you need to make that entry into the .profile file of your home directory.
to find out the file go to your home directory and type
$ ls -latr
This command will show all hidden files (.profile is also a hidden file)
Then edit the file using vi editor i.e.
$ vi .profile
Make the desired entries and save the file , same can be seen in below screenshots.
Then just restart your system , to let the .profile execute and make your shortcuts permanent🙂🙂
