How do I determine if a directory is a mounted NFS mount point in shellscript
Question
I want to write a sh/bash script that can determine whether a particular directory is a mount point for an NFS filesystem.
eg something like
$ mkdir localdir
$ mkdir remotedir
$ mount host:/share ./remotedir
$ classify_dirs.sh
--> localdir is local
--> remotedir is an NFS mount point
Solution
This question is effectively a dup of how-can-i-tell-if-a-file-is-on-a-remote-filesystem-with-perl
The short answer is to use the stat
command
eg
$ stat -f -L -c %T localdir
ext2/ext3
$ stat -f -L -c %T remotedir
nfs
Then a directory is an NFS mount point if its type is 'nfs' and its parent directory isn't.
