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.
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.
Ooh. I like that. I’m gonna try that, thanks.
Haha, my bad!
Fortunately I have my hourly backups! 😅
I just start every command with a space, don’t see the issue.
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.
Fuck, I just cleared my history.
What does it do again?
🤣

Yes, my comment only applies to the shell history in memory. -c clears history immediately, but you can still reload it from disk if you haven’t overwritten that with -w. If you tend to close your terminal windows frequently and rely on the history feature between sessions, it would benefit you to learn about the intricacies of the on-disk copy of history and how its affected by writes, appends, clears, crashes, etc. I tend to leave my terminal windows open a long time and copy any complex commands out to my PKM if I need to save them for future sessions, so I generally try not to rely on .bash_history, but it has saved my bacon on more than one occasion.
