The umount command allows local and remote resources to be unmounted. It makes no difference here whether the resource was mounted explicitly with the mount command or implicitly via the file /etc/vfstab.
Only the unmounting of remote resources is described here (file system type nfs). For a description of how to unmount local resources (file system type ufs or bs2fs), refer to the "POSIX Commands” manual, umount command.
Authorization: The command can only be entered with root authorization.
Syntax
