Name
umount — stdin stdout - file -- opt --help --version
Synopsis
umount [options] [device|directory]
umount does the opposite of
mount: it makes a disk partition
unavailable via the filesystem. For instance, if you’ve mounted a
CD-ROM disc, you can’t eject
it until it’s umounted:
$ umount /media/cdrom
Always unmount a removable medium before ejecting it or you risk damage to its filesystem. To unmount all mounted devices:
# umount -a
Don’t unmount a filesystem that’s in use; in fact, the
umount command will refuse to do
so for safety reasons.
