image of a cat looking at a bunch of paper a woman shows it, with the header “cat ~/.bash_history”
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:
1 Abcd 2 Efgh 3 IjklIf 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

HISTFILE="", which amounts to the same thing.Not quite. Unsetting
HISTFILE, or setting it to an invalid path will mean the shell doesn’t update the history file while it quits.set +o historymakes the shell stop recording until you doset -o history, which is useful if you want shell history generally, but don’t want some specific commands to be recorded - if you just unset HISTFILE, the commands still show up if you press the up arrowReal OGs put a space right after the prompt.
