Where does this belong in the filesystem?
Know how to see which device a file belongs to.
From time to time, I have to rediscover how to do this.
This being a very simple thing: find out which underlying device is actually holding a file or a directory. As an example, I sometimes have to check whether there is enough space in the current directory, and in case go somewhere else.
The bottom line is that df is my friend, and I hope I will remember it when I will need this bit of information the next time:
$ df "$HOME" Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/foobarx--vg-root 36643428 15040292 19712016 44% /
This is it: just pass the path to the file/directory you want checked, and you will get back the only relevant line from df.
