I legitimately back up my history file. Mostly because it likes to truncate itself randomly (though this may have been fixed in zsh, or my config, because it's been a while). Just a systemd timer that triggers a shell script to copy it by date and rotate anything older than 100 copies.

Edit: WHY DID I SAY ANYTHING? After like 3 months of no problems, my history truncated itself to 3 entries a few minutes ago. I've only ever seen a few days of loss before that lol.

Have you tried Atuin? It's amazing.

[-] andrew@lemmy.stuart.fun 3 points 2 years ago

I did try it for a bit. IIRC it slowed me down more than I cared for. Maybe worth trying again, though.

I'm annoyed when my thirteen bash instances don't share history, but I'd probably be a lot more annoyed if they did.

[-] andrew@lemmy.stuart.fun 2 points 2 years ago

That's one thing I like about zsh, or my config at least, because I use i3 and therefore tend to open lots of shells. History is mostly local until I hit return twice (two empty prompts) at which point I can get history from other sessions. It's stuck more global at that point though aside from future history.

Ooh. I like that. I'm gonna try that, thanks.

Haha, my bad!

Fortunately I have my hourly backups! 😅

Can somebody please tell me what history -c is?

[-] survivalmachine@beehaw.org 9 points 2 years ago

history displays a list of all commands you have run on the terminal since the history list was last cleared. It is invaluable for referring back to a big complex command or set of commands you ran at some point in the past. The -c flag clears that history.

[-] zemja@programming.dev 11 points 2 years ago

Fuck, I just cleared my history.

It lets you clear the bash command history, either completely or selectively. Here's the GNU docs for the history builtin: https://www.gnu.org/software/bash/manual/html_node/Bash-History-Builtins.html#index-history

(I'm not too familiar, someone else can clarify: is this available outside bash?)

What's interesting to me is the -a option, which lets you "flush" the history for the current session without ending the session. I can see that being useful!

Don't fucking do this in zsh, it does NOT do the same thing that it does in bash.

[-] sabreW4K3@lemmy.tf 3 points 2 years ago

What does it do? 😳

[-] aCodeCrafter@lemmy.world 5 points 2 years ago

Welp, just did this to see what -c does...

Excuse me whilst I cry myself to sleep
