# umount.nfs(8)

unmount a Network File System

## 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)](/nfs/5.md) utilities package, which provides NFS client functionality.

**umount.nfs4** and **umount.nfs** are meant to be used by the [**umount**(8)](/umount/8.md) 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)](/nfs/5.md) and [**umount**(8)](/umount/8.md) manual pages.

## FILES

- */etc/fstab*

  file system table

- */etc/mtab*

  table of mounted file systems
