MOUNTPOINT

mountpoint − see if a directory is a mountpoint

/bin/mountpoint [−q] [−d] /path/to/directory
/bin/mountpoint −x /dev/device

Mountpoint checks if the directory is a mountpoint.

−q

Be quiet - don’t print anything.

−d

Print major/minor device number of the filesystem on stdout.

−x

Print major/minor device number of the blockdevice on stdout.

Zero if the directory is a mountpoint, non-zero if not.

Symbolic links are not followed, except when the -x option is used. To force following symlinks, add a trailing slash to the path of the directory.

The name of the command is misleading when the -x option is used, but the option is useful for comparing if a directory and a device match up, and there is no other command that can print the info easily.
