I need a command which outputs "/dev/loop0" when
"/tmp/xyz/symlink/mnt" is
given.
$ findmnt -no SOURCE /tmp/xyz/symlink/mnt
/dev/loop0
Thank's. Now I remember that you have told me that already one day. :)
BTW is there also a way to get "findmnt -n -o SOURCE" working if the
argument is not a mount point but a regular file on another mount
point? (In opposite of my initial question.)
I don't like that all these questions here are answered using "df".
