Modifing bashrc file with Aliases

I thought it would be neat to create a Alias in bashrc using nano to give a password respond for a sudo command in tty. However it seems I’ve bitten off more than I can chew. I ran into a syntax problem in my defining my Alias as I followed an example I found in a search online that did not work as stated. I believe I should be using the “if, then” conditional statement, If “password for mark”, then =“password” but not sure of this statement. Also, in scrolling through bashrc I came across comments about creating additional Aliases in bashrc, instructing user to create a folder in directory etc for Aliases rather than bashrc. I welcome any help.

You could install Bash-It

Just going thru the installations folders can give you the clues you need.
