.SH DESCRIPTION
.sp
.LP
\fBquotaon\fR turns on disk quotas for one or more ufs file systems.
.sp
.LP
Before a file system may have quotas enabled, a file named \fBquotas\fR, owned
by root, must exist in the root directory of the file system. See
\fBedquota\fR(8) for details on how to modify the contents of this file.
.sp
.LP
\fBquotaoff\fR turns off disk quotas for one or more ufs file systems.
.sp
.LP
The file systems specified must already be mounted.
.sp
.LP
These commands update the \fBmntopts\fR field of the appropriate entries in
\fB/etc/mnttab\fR to indicate when quotas are on or off for each file system.
If quotas are on, the string \fBquota\fR will be added to \fBmntopts\fR; if
quotas are off, the \fBquota\fR string is not present.
.sp
.LP
\fIfilesystem\fR must be either the mount point of a file system, or the block
device on which the file system resides.
.SH OPTIONS

directory.
