MOUNTPOINT(1)						Linux System Administrator's Manual					     MOUNTPOINT(1)

NAME
       mountpoint - see if a directory is a mountpoint

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

DESCRIPTION
       Mountpoint checks if the directory is a mountpoint.

OPTIONS
       -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.

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

NOTES
       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.
