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.
