QUOTA(1) BSD Reference Manual QUOTA(1)
quota - display disk usage and limits
quota [-q | -v] [-gu] quota [-q | -v] -g group ... quota [-q | -v] -u user ...
quota displays users' disk usage and limits. By default only the user quotas are printed. The options are as follows: -g Print group quotas for the group of which the user is a member. -q Print a more terse message, containing only information on filesystems where usage is over quota. -u Print user quotas for the user. This flag is equivalent to the default. -v quota will display quotas on filesystems where no storage is al- located. Specifying both -g and -u displays both the user quotas and the group quotas (for the user). Only the superuser may use the -u flag and the optional user argument to view the limits of other users. Non-superusers can use 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 tries to report the quotas of all mounted filesystems. If the filesystem is mounted via NFS, it will attempt to contact the rpc.rquotad(8) daemon on the NFS server. For FFS filesystems, quotas must be turned on in /etc/fstab. 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 /etc/fstab to find filesystem names and locations
