DESCRIPTION
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. If a numeric ID is given instead of a name,
that UID/GID will be used even if there is not a corresponding ID in the
/etc/passwd or /etc/group
files. 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 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 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.
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 -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/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 filesystems with user quotas specified in
/etc/fstab. When invoked with the
-g flag the grace period is set for all the
filesystems 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.
Only the superuser may edit quotas.
