.SH "NAME"
fs_diskfree \- Shows data about the partition housing a directory or file
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"

.PP
\&\fBfs di\fR [\fB\-p\fR\ <\fIdir/file\ path\fR>+] [\fB\-hu\fR] [\fB\-he\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBfs diskfree\fR command formats and displays information about the
partition that houses the volume containing the specified directory or
file, including its size and how much space is currently used.
.PP
To display information about the volume itself, use the \fBfs examine\fR
command. The \fBfs examine\fR and \fBfs quota\fR commands also display
information about a volume.
.SH "CAUTIONS"
.IX Header "CAUTIONS"
The partition-related statistics in this command's output do not always
agree with the corresponding values in the output of the standard \s-1UNIX\s0
\&\fBdf\fR command. The statistics reported by this command can be up to five
minutes old, because the Cache Manager polls the File Server for partition
information at that frequency. Also, on some operating systems, the \fBdf\fR
command's report of partition size includes reserved space not included in
this command's calculation, and so is likely to be about 10% larger.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-path\fR <\fIdir/file path\fR>+" 4
.IX Item "-path <dir/file path>+"
Names a file or directory that resides on the partition about which to
produce output. Partial pathnames are interpreted relative to the current
working directory, which is also the default value if this argument is
omitted.
.IP "\fB\-human\fR" 4
.IX Item "-human"
Print space in a \*(L"human-readable\*(R" format. Instead of always printing space
in kilobytes, show disk space in kilobytes, megabytes, gigabytes,
terabytes, or petabytes, as appropriate.
.IP "\fB\-help\fR" 4
.IX Item "-help"
Prints the online help for this command. All other valid options are
ignored.
.SH "OUTPUT"
.IX Header "OUTPUT"
The output reports the following information about the volume and
partition that houses each file or directory:
.IP "Volume Name" 4
.IX Item "Volume Name"
The name of the volume.
.IP "total" 4
.IX Item "total"
The partition's total size. If \fB\-human\fR is not specified, this value is
in kilobytes.
.IP "used" 4
.IX Item "used"
The amount of space used on the partition. If \fB\-human\fR is not specified,
this value is in kilobytes.
.IP "avail" 4
.IX Item "avail"
The amount of space available on the partition. If \fB\-human\fR is not
specified, this value is in kilobytes.
.ie n .IP "%used" 4
.el .IP "\f(CW%used\fR" 4
.IX Item "%used"
The percentage of the partition's total space that is used (the \f(CW\*(C`used\*(C'\fR
statistic divided by the \f(CW\*(C`kbytes\*(C'\fR statistic, times 100).
.PP
If the \f(CW%used\fR statistic is greater than 90%, it is marked with the
string \f(CW\*(C`<<WARNING\*(C'\fR at the right margin.
.PP
If the volume is a read-only volume, the output includes information about
only one of the partitions that houses it, generally the one on the file
server machine with the lowest preference rank. To verify which machine
the output is referring to, use the \fBvos listvldb\fR command to list the
volume's locations, and the \fBvos partinfo\fR command to display the size of
each one.
.SH "EXAMPLES"
.IX Header "EXAMPLES"
The following example shows the output for the partitions housing the
volumes \f(CW\*(C`user.smith\*(C'\fR and \f(CW\*(C`sun4x_56.bin\*(C'\fR:
.PP
.Vb 4
\&  % fs diskfree \-path /afs/example.com/usr/smith /afs/example.com/sun4x_56/bin

.Ve
.SH "PRIVILEGE REQUIRED"
.IX Header "PRIVILEGE REQUIRED"
The issuer must have the \f(CW\*(C`r\*(C'\fR (read) permission on the \s-1ACL\s0 of the root
directory of the volume that houses the file or directory named by the
\&\fB\-path\fR argument, and \f(CW\*(C`l\*(C'\fR (list) permission on the \s-1ACL\s0 of each 
directory that precedes it in the pathname.
