# [NAME](#NAME)

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

# [SYNOPSIS](#SYNOPSIS)

**umount.nfs dir \[-fvnrlh ]**

# [DESCRIPTION](#DESCRIPTION)

**umount.nfs** and **umount.nfs4** are a part of [**nfs**(5)](/man/os/nfs-utils/nfs.5) utilities package, which provides NFS client functionality.

**umount.nfs4** and **umount.nfs** are meant to be used by the [**umount**(8)](/man/os/nfs-utils/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](#OPTIONS)

[**-f**](#f)

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

[**-v**](#v)

Be verbose.

[**-n**](#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**](#r)

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

[**-l**](#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**](#h)

Print help message.

# [NOTE](#NOTE)
