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’m a big enjoyer of pushd and popd
so if youre in a working dir and need to go work in a different dir, you can pushd ./, cd to the new dir and do your thing, then popd to go back to the old dir without typing in the path again
I love these.
pushd can also take a path so that you don’t have to do a cd after
Nice! I didn’t know that one.
You can also cd to a directory and then do
cd -to go to the last directory you were in.
