And there goes my daily new knowledge snippet! Thanks!

To add,

!$ gets replaced with the last word from the previous command line

!! Repeats the most recent command

!-N Repeats the Nth previous command

!string Repeats the most recent command that began with 'string'

Holy fucking shit. I've dabbled in Linux for so long to not know. Thank you!

I think, if your using bash

alt + .

Does the same thing as typing

!$

ls /super/long/path/to/dir

cd alt + .

I believe if you hit it again, it cycles through all previous last words

In some shells (e.g. fish), "running" a directory changes to it so you can save keystrokes and just delete the "ls ".

I like the way you think! Too bad a I replied to a seaming empty post some 26 min after you. I always disliked this about Reddit. Seeing someone rewording the top reply for karma.
