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.
FILES¶
- quota.user
- at the file system root with user quotas
- quota.group
- at the file system root with group quotas
- /etc/fstab
