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’.
ctrl+r on bash will let you quickly search and execute previous commands by typing the first few characters usually.
it’s much more of a game changer than it first meets the eye.
And I believe shift+r will let you go forward in history if you’re spamming ctrl+r too fast and miss whatever you’re looking for
