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’.


when I forget to include sudo in my command:
sudo !!Also if you make a typo you can quickly fix it with ^, e.g.
ls /var/logs/apache^logs^logAnd if an argument recurs, global replacement is:
^foo^bar^:&Similar-ish for quickly editing last command:
I learned about this through Bread On Penguins, she did a vid on useful commands

with zsh, you can use it, and then press space to have the !! replaced by the previous command to be able to edit it :)
