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’.
Is there a version of $_ that works with mv? It just keeps renaming my files to “filedir,” I’m trying sort through a directory and move some files to another for keeping, be easier if I could do:
mv picture1.jpg /path/to/keepdirectory
then do something like
mv picture2.jpg $_
And so on. But with that I’d just be renaming all my photos “filedir” instead of moving them lol.
