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’d say that journalctl is not only boot, but every service that runs on the computer has its logs collected through it, so you can use it as
journalctl --grep="your regex". You can also add-kto check kernel logs,-b -nto check nth precedent boot or-b nto check the absolute nth boot. There is a lot that you can check with it and it is quite nice :)Otherwise, I like eza as an ls replacement, or batcat as a human friendly cat
Don’t forget the almighty:
journalctl -fu <servicename>And yes, I am always reading that as “fuck you, service”.
Well now I’m aliasing this to
jofuand remembering it as “jerk off fuck you”I love it XD
