Quota
displays users' disk usage and limits.
By default only the user quotas are printed.
-g
Print group quotas for the group
of which the user is a member.
The optional
-u
flag is equivalent to the default.
-v
will display quotas on filesystems
where no storage is allocated.
-q
Print a more terse message,
containing only information
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.
