How to get filesystem in bash script

Hi,

Is there some way of extracting the filesystem id/name given a file name in
bash? I want to test whether 2 files are in the same filesystem.

I thought I could use `stat -fc "%i" $filename` but it always responds with
0

You can use df, but you'll then need to parse the output somewhat. Eg:

gordon @ yakko: pwd
/usr/src/linux
gordon @ yakko: df Makefile
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda4 75340676 65492216 6021376 92% /var

gordon @ yakko: df /etc/logrotate.conf
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda1 482248 210237 247111 46% /

This might give you what you want, but I'm sure there might be easier
ways to do it:

df /etc/logrotate.conf | fgrep /dev/ | awk '{printf $1;}'

Another way might be the -i option to ls to give the files inode
number. If it's the same file on the same filing system it will have
the same inode number, but there is a small possiblity that it might
just have the same inode number on a different filing system..
