A colleague mocked me the other day because I didn't know about the "history" command and I was using "cat .bash_history"
So, yk how the history command outputs something like this:
If you run
!2
, you will runEfgh
.It blew my mind the first time I saw it, but maybe I'm just stupid.
I actually use quite frequently "sudo !!“, but I didn't know the details of why it worked...
Now I see more sense in using the history command, specially combined with grep.
Same here, I just assumed it was a special thing that saved the last command. Had no idea it was actually a query to the history
