MIPS stuff done, back to C. Yay!

This week the lectures covered the associated metadata of files on a Unix system

Originally the code didn’t work for directories outside of the current directory.
That was because the file path returned from the readdir function was a path relative to the directory entry it was given.

Consequently, lstat wasn’t opening the right file, and gave us wrong results.
To fix that I just had to pass lstat an absolute path.

It sort of reminds me of the start of 2015, where a popular application had a major flaw

APPROOT="$(cd '${0%/*}' && echo $PWD)"
rm -rf "$APPROOT/"*

Issue with this, is that if $APPROOT is empty, then rm -rf "/*" - and there goes all of our files.
Better hope you’re not running it as root.
But even if you’re not… unlucky.
