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.
