edquota - edit user quotas for ufs file system


edquota [-p proto_user] username...

edquota -t


edquota is a quota editor. 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 for each mounted
ufs file system that has a quotas file, and an editor is then invoked on
the file. The quotas may 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 vi(1) unless the EDITOR environment variable
specifies otherwise.

Only the super-user may edit quotas. In order for quotas to be
established on a file system, the root directory of the file system must
contain a file, owned by root, called quotas. (See quotaon(8).)

proto_user and username can be numeric, corresponding to the UID of a
user. Unassigned UIDs may be specified; unassigned names may not. In this
way, default quotas can be established for users who are later assigned a

If no options are specified, the temporary file created will have one or
more lines of the format, where a block is considered to be a 1024 byte
(1K) block:

fs mount_point blocks (soft =number, \
hard =number ) inodes (soft =number, \
hard =number)

The number fields may be modified to reflect desired values.


The following options are supported:

Duplicate the quotas of the proto_user specified for each username
specified. This is the normal mechanism used to initialize quotas
for groups of users.

Edit the soft time limits for each file system. If the time limits
are zero, the default time limits in
/usr/include/sys/fs/ufs_quota.h are used. The temporary file
created will have one or more lines of the form

fs mount_point blocks time limit = number tmunit, files time limit
= number tmunit

tmunit may be one of ``month'', ``week'', ``day'', ``hour'', ``min'' or
``sec''; characters appended to these keywords are ignored, so you may
write ``months'' or ``minutes'' if you prefer. The number and tmunit
fields may be modified to set desired values. Time limits are printed in
the greatest possible time unit such that the value is greater than or
equal to one. If ``default'' is printed after the tmunit, this indicates
that the value shown is zero (the default).


See largefile(7) for the description of the behavior of edquota when
encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
