WDYM your terminal isn't a test suite?

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.

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 -c is?

- 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?

  dont you also need history -w to save it?
  
  on ubuntu -c doesnt actually clear it unless you also use -w

- 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!

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

Excuse me whilst I cry myself to sleep

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

- What does it do? 😳

Can someone explain, I don't get it.

- If you clear your history, you feel like a SpongeBob popsicle for some reason? That's what I'm reading. Gotta be it.

  Weird, I clear my history very frequently and never once felt like a SpongeBob popsicle.
