edquota - edit user quotas
SYNOPSIS
edquota [ -p protoname ] [ -u | -g ] [ -r ] [ -F format-name ] [ -f filesystem ] username...
edquota [ -u | -g ] [ -F format-name ] [ -f filesystem ] -t
edquota [ -u | -g ] [ -F format-name ] [ -f filesystem ] -T username | groupname...
DESCRIPTION
edquota is a quota editor. One or more users or groups may be specified on the command line. If a number is
given in the place of user/group name it is treated as an UID/GID. For each user or group a temporary file is
created with an ASCII representation of the current disk quotas for that user or group and an editor is then
invoked on the file. The quotas may then be modified, new quotas added, etc. Setting a quota to zero indicates
that no quota should be imposed.
Users are permitted to exceed their soft limits for a grace period that may be specified per filesystem. Once
the grace period has expired, the soft limit is enforced as a hard limit.
The current usage information in the file is for informational purposes; only the hard and soft limits can be
changed.
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 either the EDITOR or the VISUAL environment variable specifies otherwise.
Only the super-user may edit quotas.
OPTIONS
-r, --remote
Edit also non-local quota use rpc.rquotad on remote server to set quota. This option is available only if
quota tools were compiled with enabled support for setting quotas over RPC. The -n option is equivalent,
and is maintained for backward compatibility.
-u, --user
Edit the user quota. This is the default.
-g, --group
Edit the group quota.
-p, --prototype=protoname
Duplicate the quotas of the prototypical user specified for each user specified. This is the normal mech-
anism used to initialize quotas for groups of users.
-F, --format=format-name
Edit quota for specified format (ie. don't perform format autodetection). Possible format names are:
vfsold (version 1 quota), vfsv0 (version 2 quota), rpc (quota over NFS), xfs (quota on XFS filesystem)
-f, --filesystem filesystem
Perform specified operations only for given filesystem (default is to perform operations for all filesys-
tems with quota).
-t, --edit-period
Edit the soft time limits for each filesystem. In old quota format if the time limits are zero, the
default time limits in <linux/quota.h> are used. In new quota format time limits must be specified (there
is no default value set in kernel). Time units of 'seconds', 'minutes', 'hours', and 'days' are under-
stood. Time limits are printed in the greatest possible time unit such that the value is greater than or
equal to one.
-T, --edit-times
Edit time for the user/group when softlimit is enforced. Possible values are 'unset' or number and unit.
Units are the same as in -t option.
FILES
aquota.user or aquota.group
quota file at the filesystem root (version 2 quota, non-XFS filesystems)
quota.user or quota.group
quota file at the filesystem root (version 1 quota, non-XFS filesystems)
/etc/mtab mounted filesystems table
