Anything you have trouble remembering, or just find yourself doing often, create an alias (or bash script if it constitutes a multi line command). Name the alias something you can easily remember that also lets you know what that command does.
Then, and here's he trick, don't rely on the alias. Use it when you can't remember, say "aww, damn it I had to use the alias again", and then use which followed by the alias name to see what the command was again. Do this over and over and eventually some commands will stick.
Ones that you don't care about or are just super long, just keep using the alias and don't worry about remembering them. Use aliases as both commands and notes.
