DESCRIPTION
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.
OPTIONS
- -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)
 - -g
 - 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).
 - -u
 - flag is equivalent to the default.
 - -v
 - will display quotas on filesystems where no storage is allocated.
 - -s
 - option will make quota(1) try to choose units for showing limits, used space and used inodes.
 - -i
 - ignore mountpoints mounted by automounter
 - -l
 - report quotas only on local filesystems (ie. ignore NFS mounted filesystems).
 - -q
 - Print a more terse message, containing only information on filesystems where usage is over quota.
 - -Q
 - 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.
DIAGNOSTICS
If quota exits with a non-zero status, one or more filesystems are over quota.
FILES

 - quota.user or quota.group
