NAME

       umount.nfs, umount.nfs4 - unmount a Network File System

SYNOPSIS

       umount.nfs dir [-fvnrlh ]

DESCRIPTION

       umount.nfs  and  umount.nfs4  are  a  part of nfs(5) utilities package, which provides NFS
       client functionality.

       umount.nfs4 and umount.nfs are meant to be used by the umount(8)  command  for  unmounting
       NFS  shares.  This  subcommand,  however,  can  also  be used as a standalone command with
       limited functionality.

       dir is the directory on which the file system is mounted.

OPTIONS

       -f     Force unmount the file system in case of unreachable NFS system.

       -v     Be verbose.

       -n     Do not update /etc/mtab.  By default, an entry is created in  /etc/mtab  for  every
              mounted file system. Use this option to skip deleting an entry.

       -r     In case unmounting fails, try to mount read-only.

       -l     Lazy  unmount.  Detach  the  file  system  from  the file system hierarchy now, and
              cleanup all references to the file system as soon as it is not busy anymore.

       -h     Print help message.

NOTE

       For further information please refer nfs(5) and umount(8) manual pages.
