.TH UMOUNT 8 ubase-VERSION
.SH NAME
\fBumount\fR - Unmount file systems
.SH SYNOPSIS
\fBumount\fR [\fB-lfn\fR] \fItarget...\fR
.TP
\fBumount\fR \fB-a\fR [\fB-lfn\fR]
.SH DESCRIPTION
\fBumount\fR detaches the \fItarget\fR filesystem(s).
A file system is specified by giving the directory where it
has been mounted. Giving the special device on which the file system
lives may also work, but is obsolete, mainly because it will fail in
case this device was mounted on more than one directory.
.SH OPTIONS
.TP
\fB-l\fR
Lazy unmount. Detach the filesystem from the fs hierarchy now, and cleanup
all references to the filesystem as soon as it is not busy anymore.
.TP
\fB-f\fR
Force unmount (in case of an unreachable NFS server).
.TP
\fB-n\fR
Unmount without writing in /etc/mtab. This is the default action.
.TP
\fB-a\fR
All of the file systems described in /proc/mounts are unmounted. The
proc filesystem is not unmounted.
.SH SEE ALSO
umount(2), mount(8)
