umount — Unmount filesystems
umount -h | -V
-h, --help output usage information and exit -U, --remove-user-mounts remove all user mounts -V, --version output version information and exit
The umount program removes mounts from the mount
table in the current session. If you specify a POSIX path that
corresponds to a current mount point, umount will
remove it from the current mount table. Note that you can only remove
user mount points. The
-U flag may be used to specify
removing all user mount points from the current user session.
See the section called “The Cygwin Mount Table” for more information on the mount table.
