edquota - edit user quotas
edquota [-u] [-p proto-username] username | uid [...]
edquota -g [-p proto-groupname] groupname | gid [...]
edquota -t [-u]
edquota -t -g
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 cur-
rent 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 speci-
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 speci-
fied 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.
