edquota - edit user quotas

edquota is a quota editor. One or more users, groups, or projects may
be specified on the command line. If a number is given in the place of
user/group/project name it is treated as an UID/GID/Project ID. For
each user, group, or project a temporary file is created with an ASCII
representation of the current disk quotas for that user, group, or
project 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.
Block usage and limits are reported and interpreted as multiples of
kibibyte (1024 bytes) blocks by default. Symbols K, M, G, and T can be
appended to numeric value to express kibibytes, mebibytes, gibibytes,
Inode usage and limits are interpreted literally. Symbols k, m, g, and
t can be appended to numeric value to express multiples of 10^3, 10^6,
10^9, and 10^12 inodes.
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 pur‐
poses; 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.
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 compati‐
Currently, pathnames of NFSv4 mountpoints are sent without lead‐
ing slash in the path. rpc.rquotad uses this to recognize NFSv4
mounts and properly prepend pseudoroot of NFS filesystem to the
path. If you specify this option, edquota will always send paths
with a leading slash. This can be useful for legacy reasons but
be aware that quota over RPC will stop working if you are using
Edit the user quota. This is the default.
Edit the group quota.
Edit the project quota.
Duplicate the quotas of the prototypical user specified for each
user specified. This is the normal mechanism used to initialize
quotas for groups of users.
Always try to translate user / group name to uid / gid even if
the name is composed of digits only.
Edit quota for specified format (ie. don't perform format
autodetection). Possible format names are: vfsold Original
quota format with 16-bit UIDs / GIDs, vfsv0 Quota format with
32-bit UIDs / GIDs, 64-bit space usage, 32-bit inode usage and
limits, vfsv1 Quota format with 64-bit quota limits and usage,
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 filesystems with quota).
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.
Edit time for the user/group/project when softlimit is enforced.
Possible values are 'unset' or number and unit. Units are the
same as in -t option.
