quota - display disk usage and limits


quota [ -F format-name ] [ -guvxsil | q ]
quota [ -F format-name ] [ -uvxsil | q ] user...
quota [ -F format-name ] [ -gvxsil | q ] group...


quota displays users' disk usage and limits. By default only the user quotas are printed.

quota reports the quotas of all the filesystems listed in /etc/mtab. For filesystems that are NFS-mounted a call to the rpc.rquotad on the server machine is performed to get the information.


-F format-name
Show 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)
Print group quotas for the group of which the user is a member. The optional group argument(s) restricts the display to the specified group(s).
flag is equivalent to the default.
will display quotas on filesystems where no storage is allocated.
option will make quota(1) try to choose units for showing limits, used space and used inodes.
ignore mountpoints mounted by automounter
report quotas only on local filesystems (ie. ignore NFS mounted filesystems).
Print a more terse message, containing only information on filesystems where usage is over quota.
Always try to translate name to id, even if it is composed of only digits.
Do not print error message if connection to rpc.rquotad is refused (usually this happens when rpc.rquotad is not running on the server).

Specifying both -g and -u displays both the user quotas and the group quotas (for the user).

Only the super-user may use the -u flag and the optional user argument to view the limits of other users. Non-super-users can use the the -g flag and optional group argument to view only the limits of groups of which they are members.

The -q flag takes precedence over the -v flag.


If quota exits with a non-zero status, one or more filesystems are over quota.


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)
default filesystems
