setquota is a command line quota editor. The filesystem, user/group/project name and new quotas for this filesystem can be specified on the command line. Note that if a number is given in the place of a user/group/project name it is treated as an UID/GID/project ID.

Edit also remote 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.
Currently, pathnames of NFSv4 mountpoints are sent without leading 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, setquota 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 new rpc.rquotad.
Perform setting 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)
Set user quotas for named user. This is the default.
Set group quotas for named group.
Set project quotas for named project.
Use quota settings of user, group or project protoname to set the quota for the named user, group or project.
Always try to translate user / group / project name to uid / gid / project ID even if the name is composed of digits only.
Read information to set from stdin (input format is name block-softlimit block-hardlimit inode-softlimit inode-hardlimit ). Empty lines and lines starting with # are ignored.
If parsing of an input line in batch mode fails, continue with processing the next line.
Set grace times for users/groups/projects. Times block-grace and inode-grace are specified in seconds.
Alter times for individual user/group/project when softlimit is enforced. Times block-grace and inode-grace are specified in seconds or can be string 'unset'.
Go through all filesystems with quota in /etc/mtab and perform setting.

block-softlimit and block-hardlimit are 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, and tebibytes.

inode-softlimit and inode-hardlimit 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.

To disable a quota, set the corresponding parameter to 0. To change quotas for several filesystems, invoke once for each filesystem.

Only the super-user may edit quotas.
