Edits the quotas of one or more groups, specified by
groupname from the command line. When used with the -t
option, sets or changes the grace period for all file systems
with group quotas specified in the /etc/fstab file.
Edits the quotas of one or more groups, specified by
groupID from the command line. When used with the -t
option, sets or changes the grace period for all file systems
with group quotas specified in the /etc/fstab file.
Initializes the specified quotas by duplicating the established
quotas of the prototypical user's name (when used
with the -u option, the -U option, or no other options),
or the prototypical group's name (when used with the -g or
-G options). The proto_username or proto_groupname must
have a valid quota file. Establishing quotas for one user
or group and then using the -p option to duplicate these
quotas for other users is the normal mechanism for initializing
quotas for a group of users. Initializes the
specified quotas by duplicating the established quotas of
the prototypical user's id (when used with the -U option
or the -u option), or the prototypical group's id (when
used with the -G option or the -g option). The
proto_userID or proto_groupID must have a valid quota
file. Establishing quotas for one user or group and then
using the -P option to duplicate these quotas for other
users is the normal mechanism for initializing quotas for
a group of users. Sets or changes the default grace
period for which users may exceed their soft limits. To
set a temporary grace period, enter the edquota command
with the -t option and set the soft limit for the number
of blocks or inodes to 1 and the hard limit for the number
of blocks or inodes to 0 (zero). By default, or when you
specify -t with the -u option, the grace period is set for
all file systems with user quotas specified in the
/etc/fstab file. When you specify -t with the -g option,
the grace period is set for all of the file systems with
group quotas specified in the /etc/fstab file. Edits the
quotas of one or more users, specified by username ...
from the command line. The -u option, used with the -t
option, changes the grace period for all file systems with
user quotas specified in the /etc/fstab file. The -u
option is the default and can be omitted from the command.
Edits the quotas of one or more users, specified by userID
... from the command line. The -U option used with the
-t option, changes the grace period for all file systems
with user quotas specified in the /etc/fstab file.
Specifies a prototypical user or group by the user name or
group name. A prototypical user or group has previouslydefined,
valid quota files that you want to duplicate for
other user or group quota files. Specifies a prototypical
user or group by the user ID or group ID. A prototypical
user or group has previously-defined, valid quota files
that you want to duplicate for other user or group quota
files.
The edquota command invokes an editor that allows you to
add and modify user and group quotas and modify file system
quota grace periods. Use the quota command to display
the existing quota information. Note that disk quotas are
displayed as 1 kilobyte blocks.
For each user and group specified (using -u or -g, respectively),
the edquota command creates a temporary file with
an ASCII representation of the current quotas for that
user or group, then invokes an editor to allow you to modify
the file. The vi editor is invoked by default. To
override the default, specify a different editor for the
EDITOR environment variable in your login file. To change
quota values, edit the numbers in the hard and soft limits
fields and exit the editor.
Setting a hard limit to 0 (zero) indicates that no quota
should be imposed. Setting a hard limit to 1 indicates
that no allocations should be permitted. If you set the
soft limit to 1 (one) and the hard limit to 0 (zero),
files can only be created for the length of time specified
by the grace period (default of 7 days). The current usage
information in the file is for informational purposes;
only the hard and soft limits can be changed.
Hard and soft quota limits for the number of files are
non-inclusive. You can only create files if you remain
below the limit. For example, if your hard limit is 1000
files, you can only create 999 files. Hard and soft quota
limits for the number of blocks are similarly non-inclusive.
For each file system, the edquota -t command creates a
temporary file with an ASCII representation of the current
grace period for that user or group, then invokes an editor
to allow you to modify the grace period. The grace
period may be specified in days, hours, minutes, or seconds.
Setting a grace period to 0 (zero) indicates that
the default grace period should be imposed. Setting a
grace period to 1 second indicates that no grace period
should be granted. When you exit the editor, edquota reads
the temporary file and modifies the quota.user and
quota.group files for the target file system to reflect
the changes made.
Changes in grace periods take effect immediately unless a
grace period is currently in effect. For example, assume
a user exceeds a soft limit and receives a grace period of
7 days. A subsequent change to a grace period of 1 day
will not affect the user's already-invoked grace period,
unless the user drops below the soft limit and exceeds it
once again. The default grace period for a file system is
specified in the quota.user and quota.group files for the
target file system.
The term file system represents either a UFS file system
or an AdvFS fileset.
The root user can exceed user and group quotas. The fileset
grace period is equal to the group grace period. When
you use the edquota command to set the group grace period,
it causes that same value to be used for the fileset grace
period.
You can use the edquota command to edit only those file
systems that are in the /etc/fstab file and have userquota
and groupquota entries.
You can use the edquota command to edit only those file
systems that are currently mounted. Editing quota information
for file systems that are currently unmounted will
not be saved on exit from the editor.
You must be the root user to edit quotas.
The default grace period is 7 days.
Set quotas for user1: /usr/sbin/edquota user1
To apply the existing quotas of the user named user1 to
the user named user2: /usr/sbin/edquota -p user1 user2
To apply the existing quotas of the user with the user ID
361 to the user with the user ID 382: /usr/sbin/edquota -P
