QUOTA(1)                                                              QUOTA(1)

       quota - display disk usage and limits

       quota [ -F format-name ] [ -guvsil | q ]
       quota [ -F format-name ] [ -uvsil | q ] user...
       quota [ -F format-name ] [ -gvsil | 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)

       -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 allo-

       -s     option will make quota(1) try to choose units for  showing  lim-
              its, used space and used inodes.

       -i     ignore mountpoints mounted by automounter

       -l     report  quotas only on local filesystems (ie. ignore NFS mounted

       -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.

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

       aquota.user  or
                           quota file at the filesystem root (version 2 quota,
                           non-XFS filesystems)
       quota.user  or
                           quota file at the filesystem root (version 1 quota,
                           non-XFS filesystems)
       /etc/mtab           default filesystems

       quotactl(2),   fstab(5),   edquota(8),    quotacheck(8),    quotaon(8),
