.SH NAME
\fBquotacheck\fP \- filesystem quota consistency checker
.SH SYNOPSIS
.B quotacheck
[ \fB\-v\fP ]
.I filesystem ...
.br
.B quotacheck
[ \fB\-v\fP ]
\fB\-a\fP
.SH DESCRIPTION
.B Quotacheck
examines each filesystem,
builds a table of current disk usage,
and compares this table against that recorded
in the disk quota file for the filesystem.
If any inconsistencies are detected, both the
quota file and the current system copy of the
incorrect quotas are updated (the latter only
occurs if an active filesystem is checked).
.PP
Available options:
.sp
.TP 15
\fB\-a\fP
If the
\fB\-a\fP
flag is supplied in place of any filesystem names,
\fBquotacheck\fP
will check all the filesystems indicated in
\fI/etc/fstab\fP
to be read-write with disk quotas.
.TP 15
\fB\-v\fP
\fBquotacheck\fP
reports discrepancies between the
calculated and recorded disk quotas.
.PP
Parallel passes are run on the filesystems required,
using the pass numbers in
.I /etc/fstab
in an identical fashion to
fsck(8).
.PP
Normally
.B quotacheck
operates silently.
.PP
.B Quotacheck
expects each filesystem to be checked to have a
quota files named
.I quotas
located at the root of the associated file system.
These defaults may be overridden in
.IR /etc/fstab .
If a file is not present, 
.B quotacheck
will create it.
.PP
.B Quotacheck
is normally run at boot time from the
.I /etc/rc.local
file, see
rc(8),
before enabling disk quotas with
quotaon(8).
.PP
.B Quotacheck
accesses the raw device in calculating the actual
disk usage for each user.
Thus, the filesystems
checked should be quiescent while
.B quotacheck
is running.
.SH FILES
.TP 15
.I quotas
at the filesystem root
.TP 15
.I /etc/fstab
default filesystems
.SH BUGS
The \fIquotas\fP file may be named arbitrarily but \fBmust\fP reside in
the filesystem for which it contains quota information.
.B Quotacheck
will give the error:
.sp
.in +0.5i
.I %s dev (0x%x) mismatch %s (0x%x)
.sp
.in -0.5i
if the \fIquotas\fP file is not in the filesystem being checked.  This
restriction is enforced by the kernel but may be lifted in the future.

.SH HISTORY
The
.B quotacheck
command appeared in 4.2BSD.
