.SH DESCRIPTION
.B quota
displays users' disk usage and limits.
By default only the user quotas are printed. By default space usage and limits
are shown in kbytes (and are named blocks for historical reasons).
.PP
.B quota
reports the quotas of all the filesystems listed in
.BR /etc/mtab .
For filesystems that are NFS-mounted a call to the rpc.rquotad on
the server machine is performed to get the information.
.SH OPTIONS
.TP
.B -F, --format=\f2format-name\f1
Show quota for specified format (ie. don't perform format autodetection).
Possible format names are:
.B vfsold
Original quota format with 16-bit UIDs / GIDs,
.B vfsv0
Quota format with 32-bit UIDs / GIDs, 64-bit space usage, 32-bit inode usage and limits,
.B vfsv1
Quota format with 64-bit quota limits and usage,
.B rpc
(quota over NFS),
.B xfs
(quota on XFS filesystem)
.TP
.B -g, --group
Print group quotas for the group 
of which the user is a member.
The optional 
.B group
argument(s) restricts the display to the specified group(s).
.TP
.B -u, --user
flag is equivalent to the default.
.TP
.B -P, --project
Print project quotas for the specified project.
.TP
.B -v, --verbose
will display quotas on filesystems
where no storage is allocated.
.TP
.B -s, --human-readable[=\f2units\f1]
option will make
.BR quota (1)
try to choose units for showing limits, used space and used inodes. Units can
be also specified explicitely by an optional argument in format [
.BR kgt
],[
.BR kgt
] where the first character specifies space units and the second character
specifies inode units.
.TP
.B --always-resolve
Always try to translate user / group name to uid / gid even if the name
is composed of digits only.
.TP
.B -p, --raw-grace
When user is in grace period, report time in seconds since epoch when his grace
time runs out (or has run out). Field is '0' when no grace time is in effect.
This is especially useful when parsing output by a script.
.TP
.B -i, --no-autofs
ignore mountpoints mounted by automounter
.TP
.B -l, --local-only
report quotas only on local filesystems (ie. ignore NFS mounted filesystems).
.TP
.B -A, --all-nfs
report quotas for all NFS filesystems even if they report to be on the same
device.
.TP
.B -f, --filesystem-list
report quotas only for filesystems specified on command line.
.TP
.B --filesystem=\f2path\f1
report quotas only for filesystem
.BR path .
This option can be specified multiple types and quota will be reported for each
specified filesystem. Unlike command line option
.B -f
remaining command like arguments are still treated as user / group / project names
to report.
.TP
.B -m, --no-mixed-pathnames
Currently, pathnames of NFSv4 mountpoints are sent without leading slash in the path.
.BR rpc.rquotad
uses this to recognize NFSv4 mounts and properly prepend pseudoroot of NFS filesystem
to the path. If you specify this option, 
.BR quota 
will always send paths with a leading slash. This can be useful for legacy reasons but
be aware that quota over RPC will stop working if you are using new
.BR rpc.rquotad .
.TP
.B -q, --quiet
Print a more terse message,
containing only information
on filesystems where usage is over quota.
.TP
.B -Q, --quiet-refuse
Do not print error message if connection to
.BR rpc.rquotad
is refused (usually this happens when
.BR rpc.rquotad
is not running on the server).
.TP
.B -w, --no-wrap
Do not wrap the line if the device name is too long. This can be useful when parsing
the output of
.BR quota (1)
by a script.
.TP
.B --show-mntpoint
Show also mount point as a filesystem identification.
.TP
.B --hide-device
Do not show device name in a filesystem identification.
.LP
Specifying both
.B \-g
and
.B \-u
displays both the user quotas and the group quotas (for
the user).
.LP
Only the super-user may use the
.B \-u
flag and the optional
.B user
argument to view the limits of other users. Also viewing of project quota
usage and limits is limited to super-user only.
Non-super-users can use the
.B \-g
flag and optional
.B group
argument to view only the limits of groups of which they are members.
.LP
The
.B \-q
flag takes precedence over the
.B \-v
flag.
.SH DIAGNOSTICS
If
.B quota
exits with a non-zero status, one or more filesystems
are over quota.
.SH FILES
