edquota - edit user quotas
edquota [-u] [-f fspath] [-p proto-username] username ...
edquota [-u] -e fspath[:bslim[:bhlim[:islim[:ihlim]]]] [-e ...] username
edquota -g [-f fspath] [-p proto-groupname] groupname ...
edquota -g -e fspath[:bslim[:bhlim[:islim[:ihlim]]]] [-e ...] groupname
edquota -t [-u] [-f fspath]
edquota -t -g [-f fspath]
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 from /etc/fstab. An editor is invoked on the ASCII file. The
editor invoked is vi(1) unless the environment variable EDITOR specifies
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 filesystem referenced by
fspath. Here bslim is soft limit on number of blocks, bslim is hard
limit on number of blocks, islim is soft limit on number of files and
ihlim is hard limit on number of files. If any of the bslim, bhlim,
islim and ihlim values are omitted, it is assumed to be zero, therefore
indicating that no quota should be imposed.
If invoked with the -f option, edquota will read and modify quotas on the
filesystem specified by fspath only. The fspath argument may be either a
special device or a filesystem mount point. The primary purpose of this
option is to set the scope for the -p option, which would overwrite quota
records on every filesystem 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 speci-
fied 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 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 super-user may edit quotas.
