Q: Accidentally ran mkfs command on already available disk

I had a volume of 350Gb attached to my Linode server. It was running out of space so I resized it to 400GB from the dashboard and restarted my server. Then I used the df -h command to check if the disk has been resized or not but it was still showing 96% used. So I first unmounted my volume usi...

hey there, I've got kind of an open ended question; even after working with Ubuntu since 10.10 I feel like there's 2/3s of the distro I still don't know (seems like I'm always finding some new configuration file or some new utility); ideally I'd like some kind of comprehensive guide of "here's all the stuff you can do" that I can slowly read my way all the way through

I've sought out books but they always tend to cover the Linux kernel and its drivers, which I already understand quite well; I'm not interested in that. What I get stuck on these days is stuff like configuring grub, what all of the config files in /etc/ do for X11, etc.

The only thing I can think of offhand is just going through the top rated questions on this site steadily and trying to collect random facts, but it feels a bit disorganized; does anyone know of a more organized way? Or did everyone else just kinda "bump into" random things that they collected into a library of knowledge?

@jrh I literally bump into things, then blog

usually starting with a "problem"

I guess I figured after a while I'd be able to figure out the "ubuntu way" of doing something and I'd be able to anticipate things better

I've been through 3 init systems.... 2 DEs with their own quirks (4 total that I've used)... and right now I have ubuntu systems covering 3 different roles :D

News: 20.04 Desktop Images will now automatically check their own integrity at boot. This should eliminate most corrupt .iso download questions. It also slows the first boot. Subsequent use of the installer can skip the integrity check using the 's' key during boot. Development thread at discourse.ubuntu.com/t/…
