NAME
edquota - edit user disk quotas
SYNOPSIS
/usr/sbin/edquota
[-p proto-user] username ...
/usr/sbin/edquota -t
DESCRIPTION
The edquota command is the quota editor. One or more user names can be specified on the command
line. For each username, a temporary file is created with a textual representation of the current disk quo-
tas for that user, and an editor is invoked on the file. The quotas can then be modified, new quotas added,
etc. 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 quotas to be established on a file system, the root directory of the file system must contain a
file named
quotas. See quota(5) for details.
Quotas can be established only for users whose user ID is less than 67,000,000. Attempts to establish quo-
tas for other users will result in an error message. This restriction will be removed in a future version of
HP-UX.
Only users who have appropriate privileges can edit quotas.
Options
-p proto_user Duplicate the quotas of the user name proto_user for each username. 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 command). 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.
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 statis-
tics for that user do not include any currently occupied file system resources. Therefore, it is necessary to
run quotacheck (see quotacheck(1M)) to collect statistics for that user’s current usage of that file system.
See quota(5) for a detailed discussion of this topic.
edquota will only edit quotas on local file systems.
