NAME
edquota - edit disk quotas
SYNOPSIS
/usr/sbin/edquota
[-p proto_name ][-u
-g] name ...
/usr/sbin/edquota
[-u-g]
-t
DESCRIPTION
The edquota command is the quota editor. One or more name of either users or groups can be specified
on the command line. For each name, a temporary file is created with a textual representation of the
current disk quotas for that user or group, and an editor is invoked on the file. The quotas can then be
modified, new quotas added, and so on. Upon leaving the editor,
edquota reads the temporary file and
modifies the binary quota files to reflect the changes made.
The editor invoked is specified by the
EDITOR environment variable. It defaults to vi (see vi (1)).
In order for user quotas to be established on a file system, the root directory of the file system must con-
tain a file named
quotas. Similarly, for group quotas, the
quota.group file must exist on the root
directory of the file system. See quota (5) for details.
Quotas can be established for all the users or groups on file systems created with largefiles enabled.
However, on HFS file systems and file systems on which largefiles is not enabled, quotas cannot be
created for user ids greater than 67,000,000. Quotas cannot be established for groups on HFS file sys-
tems.
Refer to usergroupname(5) to understand the functionality changes with the Numeric User Group Name
feature.
Only users who have appropriate privileges can edit quotas.
Options
-g Edits the quotas of one or more groups, specified by name (s).
-p proto_name
Duplicates the quotas of the group (when used with the -g option) or user proto_name
for each group or user, name. This is the normal mechanism used to initialize quotas for
groups of users.
-t Edit the time limits for each file system. Time limits are set for file systems, not users.
When a user exceeds the soft limit for blocks or inodes on a file system, a countdown
timer is started and the user has an amount of time equal to the time limit in which to
reduce usage to below the soft limit (the required action is given by the quota com-
mand). If the time limit expires before corrective action is taken, the quota system
enforces policy as if the hard limit had been exceeded. The default time limit of 0 is
interpreted to mean the value in <sys/quota.h>
, or one week (7 days). Time units of
sec(onds), min(utes), hour(s), day(s), week(s), and month(s) are understood. Time limits
are printed in the greatest possible time unit such that the value is greater than or equal
to one.
-u Edits the quotas of one or more users (the default), specified by name(s).
Temporary File Formats
Here is an example of the temporary file created for editing user block and inode quotas:
fs /mnt blocks (soft = 100, hard = 120) inodes (soft = 0, hard = 0)
fs / blocks (soft = 1000, hard = 1200) inodes (soft = 200, hard = 200)
Here is the format for editing quota time limits:
fs /mnt blocks time limit = 10.00 days, files time limit = 20.00 days
fs / blocks time limit = 0 (default), files time limit = 0 (default)
When editing (default) values, it is not necessary to remove the (default) string. For example, to
change the blocks time limit for /, changing the 0 to 4 days is sufficient.
WARNINGS
When establishing quotas for a user who has had none before, (for either blocks or inodes), the quota
statistics for that user do not include any currently occupied file system resources. Therefore, it is
