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. Unless -h,
-s, or -t are used, a
temporary file is created for each user with an ASCII representation of the
current disk quotas and grace time for that user. By default, quota for all
quota-enabled file systems are edited; the -f option
can be used to restrict it to a single file system. 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 - or unlimited indicates that no quota should be imposed. Setting a quota to zero indicates that no allocation is permited. Setting a soft limit to zero with a unlimited hard limit indicates that allocations should be permitted on only a temporary basis. The current usage information in the file is for informational purposes; only the hard and soft limits, and grace time can be changed.
Users are permitted to exceed their soft limits for a grace period that may be specified per user (or per-file system for quota version 1). Once the grace period has expired, the soft limit is enforced as a hard limit. The default grace period is one week.
By default, disk quotas are in KB, grace time in seconds. Disk and
inodes quota can be entered with a
humanize_number(9) suffix (K for kilo, M for mega, G for
giga, T for tera). Time can be entered with Y (year), W (week), D (day), H
(hour) and M (minute) suffixes. Suffixes can be mixed (see
EXAMPLES below). If the
-H option if used, current quota, disk usage and
time are displayed in a human-readable format.
On leaving the editor, edquota reads the
temporary file and modifies the on-disk quotas 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.
The -h, -s, and
-t flags can be used to change quota limits (hard,
soft and grace time, respectively) without user interaction, for usage in
e.g. batch scripts. The arguments are the new block and inode number limit
or grace time, separated by a slash. Units suffix may be used, as in the
editor above.
If the -g flag is specified,
edquota is invoked to edit the quotas of one or more
groups specified on the command line.
With quota version 2, there is a per-file system user or group
default quota to be copied to a user or group quota on the first allocation.
The -d flag adds the default quota to the list of
users or groups to edit.
For quota version 1, there is no default block/inode quota, and no
per-user/group grace time. To edit the file system-wide grace time, use
-d.
On quota2-enabled file systems, the -c
flag cause edquota to clear quota entries for the specified users or groups.
If disk or inode usages is not 0, limits are reverted to the default quota.
If disk and inode usages are 0, the existing quota entries are freed.
Only the super-user may edit quotas.
