NEVER EVER EVER.
STRIKE THAT WORD FROM YOUR MEMORY RIGHT NOW.
You're either root or you're not root. You need that extra second you get from logging in as root or entering root password to think "Is this a smart thing to do?"
Literally all it takes to hose a system is sudo rm -rf ../../* and suddenly you end up in root instead of the directory you want. Not using sudo prevents you from making a terrible mistake.
I remember reading somewhere, I think it was a Reddit TIFU thread, where someone tried that command in the new Windows 10 bash, and he was shocked to find out that it worked. Play stupid games...
Still, I never quite got how the Win 10 bash works in terms of the file system. Can someone explain it?
And on an unrelated note, I recently discovered that my bootmgr file is not in C:\ but rather somewhere in my windows installation folder. Weird. I just always found it cool to see the one file that actually lets you load up everything after that, and its just some small discreet extensionless file.
