.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is a quota editor.
|
|
By default, or if the
|
|
.Fl u
|
|
flag is specified,
|
|
one or more users may be specified on the command line.
|
|
For each user a temporary file is created
|
|
with an
|
|
.Tn ASCII
|
|
representation of the current
|
|
disk quotas for that user.
|
|
The list of file systems with user quotas is determined from
|
|
.Pa /etc/fstab .
|
|
An editor is invoked on the
|
|
.Tn ASCII
|
|
file.
|
|
The editor invoked is
|
|
.Xr vi 1
|
|
unless the environment variable
|
|
.Ev EDITOR
|
|
specifies otherwise.
|
|
.Pp
|
|
The quotas may then be modified, new quotas added, etc.
|
|
Block quotas can be specified in bytes (B), kilobytes (K),
|
|
megabytes (M), terabytes (T), petabytes (P), or exabytes (E).
|
|
If no units are specified, kilobytes are assumed.
|
|
Inode quotas can be specified in kiloinodes (K),
|
|
megainodes (M), terainodes (T), petainodes (P), or exainodes (E).
|
|
If no units are specified, the number of inodes specified are used.
|
|
If the
|
|
.Fl h
|
|
flag is specified, the editor will always display the
|
|
block usage and limits in a more human readable format
|
|
rather than displaying them in the historic kilobyte format.
|
|
Setting a quota to zero indicates that no quota should be imposed.
|
|
Setting a hard limit to one indicates that no allocations should
|
|
be permitted.
|
|
Setting a soft limit to one with a hard limit of zero
|
|
indicates that allocations should be permitted only on
|
|
a temporary basis (see
|
|
.Fl t
|
|
below).
|
|
The current usage information in the file is for informational purposes;
|
|
only the hard and soft limits can be changed.
|
|
.Pp
|
|
On leaving the editor,
|
|
.Nm
|
|
reads the temporary file and modifies the binary
|
|
quota files to reflect the changes made.
|
|
.Pp
|
|
If the
|
|
.Fl p
|
|
option is specified,
|
|
.Nm
|
|
will duplicate the quotas of the prototypical user
|
|
specified for each user specified.
|
|
This is the normal mechanism used to
|
|
initialize quotas for groups of users.
|
|
If the user given to assign quotas to is a numerical uid
|
|
range (e.g.\& 1000-2000), then
|
|
.Nm
|
|
will duplicate the quotas of the prototypical user
|
|
for each uid in the range specified.
|
|
This allows
|
|
for easy setup of default quotas for a group of users.
|
|
The uids in question do not have to be currently assigned in
|
|
.Pa /etc/passwd .
|
|
.Pp
|
|
If one or more
|
|
.Fl e
|
|
.Sm off
|
|
.Ar fspath Op : Ar bslim Op : Ar bhlim Op : Ar islim Op : Ar ihlim
|
|
.Sm on
|
|
options are specified,
|
|
.Nm
|
|
will non-interactively set quotas defined by
|
|
.Ar bslim , bhlim , islim ,
|
|
and
|
|
.Ar ihlim
|
|
on each particular file system referenced by
|
|
.Ar fspath .
|
|
Here
|
|
.Ar bslim
|
|
is the soft limit on the number of blocks,
|
|
.Ar bhlim
|
|
is the hard limit on the number of blocks,
|
|
.Ar islim
|
|
is the soft limit on the number of files, and
|
|
.Ar ihlim
|
|
is the hard limit on the number of files.
|
|
If any of the
|
|
.Ar bslim , bhlim , islim ,
|
|
and
|
|
.Ar ihlim
|
|
values is omitted, it is assumed to be zero, therefore
|
|
indicating that no particular quota should be imposed.
|
|
Block quotas can be specified in bytes (B), kilobytes (K),
|
|
megabytes (M), terabytes (T), petabytes (P), or exabytes (E).
|
|
If no units are specified, kilobytes are assumed.
|
|
Inode quotas can be specified in kiloinodes (K),
|
|
megainodes (M), terainodes (T), petainodes (P), or exainodes (E).
|
|
If no units are specified, the number of inodes specified are used.
|
|
.Pp
|
|
If invoked with the
|
|
.Fl f
|
|
option,
|
|
.Nm
|
|
will read and modify quotas on the file system specified by
|
|
.Ar fspath
|
|
only.
|
|
The
|
|
.Ar fspath
|
|
argument may be either a special device
|
|
or a file system mount point.
|
|
The primary purpose of this option is to set the scope for the
|
|
.Fl p
|
|
option, which would overwrite quota records on every
|
|
file system with quotas otherwise.
|
|
.Pp
|
|
If the
|
|
.Fl g
|
|
flag is specified,
|
|
.Nm
|
|
is invoked to edit the quotas of
|
|
one or more groups specified on the command line.
|
|
The
|
|
.Fl p
|
|
flag can be specified in conjunction with
|
|
the
|
|
.Fl g
|
|
flag to specify a prototypical group
|
|
to be duplicated among the listed set of groups.
|
|
Similarly,
|
|
.Fl e
|
|
flag can be specified in conjunction with
|
|
the
|
|
.Fl g
|
|
flag to non-interactively set-up quotas on the listed set
|
|
of groups.
|
|
.Pp
|
|
Users are permitted to exceed their soft limits
|
|
for a grace period that may be specified per file system.
|
|
Once the grace period has expired,
|
|
the soft limit is enforced as a hard limit.
|
|
The default grace period for a file system is specified in
|
|
.In ufs/ufs/quota.h .
|
|
The
|
|
.Fl t
|
|
flag can be used to change the grace period.
|
|
By default, or when invoked with the
|
|
.Fl u
|
|
flag,
|
|
the grace period is set for all the file systems with user
|
|
quotas specified in
|
|
.Pa /etc/fstab .
|
|
When invoked with the
|
|
.Fl g
|
|
flag the grace period is
|
|
set for all the file systems with group quotas specified in
|
|
.Pa /etc/fstab .
|
|
The grace period may be specified in days, hours, minutes, or seconds.
|
|
Setting a grace period to zero indicates that the default
|
|
grace period should be imposed.
|
|
Setting a grace period to one second indicates that no
|
|
grace period should be granted.
|
|
Quotas must be turned off for the file system and
|
|
then turned back on for the new grace period to take effect.
|
|
.Pp
|
|
Only the super-user may edit quotas.
