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 get a lot of mileage out of the line editing commands. I think they are Emacs based and optional… but like Ctrl k, Ctrl u, Ctrl a.
I usually set vi mode to have vi(m)-like line editing but I’ve always liked Ctrl+u over Esc d d. Thankfully it still works even with vi mode enabled. Seems to also be implemented as a shortcut for a lot of login managers and in DEs for settings menus, dialog boxes and such.
It’s funny, I love vim and have never understood Emacs, but when setting up a shell it seems the Emacs commands felt more natural.
