cat ~/.bash_history | grep

[-] echindod@programming.dev 16 points 2 weeks ago

Useless use of cat?

[-] disobey2623@lemmy.dbzer0.com 2 points 2 weeks ago

You saying I can just skip cat in that command and it works?

[-] x00z@lemmy.world 9 points 2 weeks ago

history | grep 'cat'

[-] ulterno@programming.dev 0 points 2 weeks ago

My output was empty for that command.

Guess why?
Because history only gives the last few lines in my system.

grep ~/.bash_history
[-] disobey2623@lemmy.dbzer0.com 4 points 2 weeks ago

How did I not know this. Thank you!

[-] oozynozh@sh.itjust.works 2 points 2 weeks ago

it's grep STRING FILE to be precise

or awk '/STRING/′ FILE if you prefer that for some reason

[-] Hammerheart@programming.dev 2 points 2 weeks ago

Yes, it was meant to be a self deprecating admission that I have used this unnecessarily verbose command.

[-] echindod@programming.dev 2 points 2 weeks ago

Ah. Well. I can not be blameless on this. I also probably use cat unnecessarily still. But less so with grep these days. I'm getting better... I swear!
