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
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
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 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 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.
Only the super-user may edit quotas.
