Edquota
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 filesystems with user quotas is determined by scanning the mounted
filesystems for a .quota.ops.user file located at
its root. 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 on only 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. The binary quota file, .quota.user is stored
at the root of the filesystem. The default filename and root location for
the user quotas cannot be overridden.
If the -p
flag 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 -g
flag is specified,
edquota
is invoked to edit the quotas of one or more
groups specified on the command line. The list of filesystems with group
quotas is determined by scanning the mounted filesystems for a
.quota.ops.group file located at its root.
Similarly, the binary quota file, .quota.group is
stored at the root of the filesystem. The default filename and root location
for group quotas cannot be overridden. 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.
Users are permitted to exceed their soft limits for a grace period
that may be specified per filesystem. Once the grace period has expired, the
soft limit is enforced as a hard limit. The default grace period for a
filesystem is specified in /usr/include/sys/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 each filesystem with a
.quota.ops.user file located at its root. When
invoked with the -g
flag, the grace period is set
for each filesystem with a .quota.ops.group file
located at its root. 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.
Only the super-user may edit quotas.
Each of the following quota files is located at the root of the mounted filesystem. The mount option files are empty files whose existence indicates that quotas are to be enabled for that filesystem. The binary data files will be created by edquota, if they don't already exist.
quota(1), quotactl(2), quotacheck(8), quotaon(8), repquota(8)
Various messages about inaccessible files; self-explanatory.
