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.
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.
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.
Haha, my bad!
Fortunately I have my hourly backups! 😅
I just start every command with a space, don't see the issue.
Was working on a server where I did not want to put some dumb command into the history, so I add a space like you do. Press up. The command is there. The fucking insult I felt.
It's disabled by default, but you can enable it in .bashrc and then delete that edit session using a spaced command.
Edit: brain fart
it also depends on the shell, in zsh it persists on local history but does not get written to history file
Can somebody please tell me what
history -cis?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.
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
-aoption, which lets you "flush" the history for the current session without ending the session. I can see that being useful!
Welp, just did this to see what -c does...
Excuse me whilst I cry myself to sleep
🥺
