I've been setting up a new Proxmox server and messing around with VMs, and wanted to know what kind of useful commands I'm missing out on. Bonus points for a little explainer.

Journalctl | grep -C 10 'foo' was useful for me when I needed to troubleshoot some fstab mount fuckery on boot. It pipes Journalctl (boot logs) into grep to find 'foo', and prints 10 lines before and after each instance of 'foo'.

I usually spell this as !!:gs/foo/bar/ (in bash). Is there a functional difference?

! command history can also take line and word selectors. I type something like !-2:2 surprisingly often.

    I honestly have no idea! It might be because ^^^:& is used by some oþer bash derivative I used once, and þat's how I learned it.

    Yeah, I use !-# a bunch too, just not wiþ global replacement. I'm most often just redo-ing some action wiþ a couple of file extensions.
