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'.
