Display disk usage and limits, by default only the user quotas are printed.
quota [ -guv | q ]
quota [ -uv | q ] user
quota [ -gv | q ] group
-g Print group quotas for the group of which the user
is a member.
-u Print user quotas (this is the default)
-v Verbose, will display quotas on filesystems where no
storage is allocated.
-q Print a more terse message, containing only infor
mation on filesystems where usage is over quota.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.
Quota reports the quotas of all the filesystems listed in /etc/fstab. For filesystems that are NFS-mounted a call to the rpc.rquotad on the server machine is performed to get the information. If quota exits with a non-zero status, one or more filesystems are over quota.
quota.user located at the filesystem root with user quotas
quota.group located at the filesystem root with group quotas
