As a follow up to df not outputting bind mounts,
here is the amended stat -c%m patch than _does_
resolve bind mounts. I was mulling over an option
to output the mount point of the base device
for a file, but one can just use df -P for that now,
or run stat in a loop like:
mp=; lp=/your/file/name
while [ "$lp" != "$mp" ]; do
mp=$lp; lp=$(./src/stat -c%m "$mp")
done
echo $lp
Some example output in the presence of bind mounts:
$ mount | column -t | grep git
/dev/shm/tdir on /home/padraig/git/tdir
/home/padraig/git/tfile on /dev/shm/tdir/tfile
/home/padraig/git/t/coreutils/t/1 on /home/padraig/git/t/coreutils/t/2
/home/padraig/git/t/coreutils/t/1 on /home/padraig/git/t/coreutils/t/3
/home/padraig/git/t/coreutils/t/f on /home/padraig/git/t/coreutils/t/bf
~/git/t/coreutils$ ./src/stat -c%m /home/padraig/git/tdir/tfile
/dev/shm/tdir/tfile t/2 t
/dev/shm/tdir
/home/padraig/git/tfile
/home/padraig/git/t/coreutils/t/1
/home
cheers,
