-
- <para>The <parameter moreinfo="none">dfree command</parameter> setting
- should only be used on systems where a problem occurs with the
- internal disk space calculations. This has been known to happen
- with Ultrix, but may occur with other operating systems. The
- symptom that was seen was an error of &quot;Abort Retry
- Ignore&quot; at the end of each directory listing.</para>
-
- <para>This setting allows the replacement of the internal routines to
- calculate the total disk space and amount available with an external
- routine. The example below gives a possible script that might fulfill
- this function.</para>
-
- <para>The external program will be passed a single parameter indicating
- a directory in the filesystem being queried. This will typically consist
- of the string <filename moreinfo="none">./</filename>. The script should return two
- integers in ASCII. The first should be the total disk space in blocks,
- and the second should be the number of available blocks. An optional
- third return value can give the block size in bytes. The default
- blocksize is 1024 bytes.</para>
-
- <para>Note: Your script should <emphasis>NOT</emphasis> be setuid or
- setgid and should be owned by (and writeable only by) root!</para>
-
- <para>Default: <emphasis>By default internal routines for
- determining the disk capacity and remaining space will be used.
- </emphasis></para>
-
- <para>Example: <command moreinfo="none">dfree command = /usr/local/samba/bin/dfree</command></para>
-
- <para>Where the script dfree (which must be made executable) could be:</para>
-
-<para><programlisting format="linespecific">
-#!/bin/sh
-df $1 | tail -1 | awk '{print $2&quot; &quot;$4}'
-</programlisting></para>

- <para>or perhaps (on Sys V based systems):</para>

-<para><programlisting format="linespecific">
-#!/bin/sh
-/usr/bin/df -k $1 | tail -1 | awk '{print $3&quot; &quot;$5}'
