DESCRIPTION¶
The
edquota utility is a quota editor. By default, or if the
-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 ASCII
representation of the current disk quotas for that user. The list of file
systems with user quotas is determined from
/etc/fstab. An
editor is invoked on the ASCII file. The editor invoked is
vi(1) unless the environment variable
EDITOR specifies otherwise.
The quotas may then be modified, new quotas added, etc. 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
-t below). The current usage
information in the file is for informational purposes; only the hard and soft
limits can be changed.
On leaving the editor,
edquota reads the temporary file and
modifies the binary quota files to reflect the changes made.
If the
-p option is specified,
edquota 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
edquota 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
/etc/passwd.
If one or more
-e
fspath[
:bslim[:bhlim[:islim[:ihlim]]]]
options are specified,
edquota will non-interactively set
quotas defined by
bslim,
bhlim,
islim, and
ihlim on each
particular file system referenced by
fspath. Here
bslim is the soft limit on the number of blocks,
bhlim is the hard limit on the number of blocks,
islim is the soft limit on the number of files, and
ihlim is the hard limit on the number of files. If any
of the
bslim,
bhlim,
islim, and
ihlim values is
omitted, it is assumed to be zero, therefore indicating that no particular
quota should be imposed.
If invoked with the
-f option,
edquota will
read and modify quotas on the file system specified by
fspath only. The
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
-p
option, which would overwrite quota records on every file system with quotas
otherwise.
If the
-g flag is specified,
edquota is
invoked to edit the quotas of one or more groups specified on the command
line. The
-p flag can be specified in conjunction with the
-g flag to specify a prototypical group to be duplicated
among the listed set of groups. Similarly,
-e flag can be
specified in conjunction with the
-g flag to
non-interactively set-up quotas on the listed set of groups.
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
<ufs/ufs/quota.h>. The
-t flag can be used to change the grace period. By default,
or when invoked with the
-u flag, the grace period is set
for all the file systems with user quotas specified in
/etc/fstab. When invoked with the
-g flag
the grace period is set for all the file systems with group quotas specified
in
/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.
Only the super-user may edit quotas.
