</PRE>
<P><STRONG>Description</STRONG>
<P>The <B>bos prune</B> command removes files from the local disk of the
server machine named by the <B>-server</B> argument, as specified by one
or more of the following flags provided on the command line:
<UL>
<P><LI>The <B>-bak</B> flag removes all files from the
<B>/usr/afs/bin</B> directory that have a <TT>.BAK</TT>
extension.
<P><LI>The <B>-old</B> flag removes all files from the
<B>/usr/afs/bin</B> directory that have a <TT>.OLD</TT>
extension.
<P><LI>The <B>-core</B> flag removes all files from the
<B>/usr/afs/logs</B> directory that have a <TT>core.</TT>
prefix.
<P><LI>The <B>-all</B> flag removes all three types of files at once.
</UL>
<P>(If none of these flags are included, the command appears to succeed, but
removes no files at all.)
<P>To display the timestamp on the current, <TT>.BAK</TT>, and
<TT>.OLD</TT> versions of one or more files, use the <B>bos
getdate</B> command.
<P><STRONG>Options</STRONG>
<DL>
<P><DT><B><B>-server</B>
</B><DD>Indicates the server machine from which to remove files. Identify
the machine by IP address or its host name (either fully-qualified or
abbreviated unambiguously). For details, see the introductory reference
page for the <B>bos</B> command suite.
<P><DT><B><B>-bak</B>
</B><DD>Removes all files from the <B>/usr/afs/bin</B> directory that have a
<TT>.BAK</TT> extension. Do not combine this flag and the
<B>-all</B> flag.
<P><DT><B><B>-old</B>
</B><DD>Removes all files from the <B>/usr/afs/bin</B> directory that have a
<TT>.OLD</TT> extension. Do not combine this flag and the
<B>-all</B> flag.
<P><DT><B><B>-core</B>
</B><DD>Removes all files from the <B>/usr/afs/logs</B> directory that have a
<TT>core.</TT> prefix. Do not combine this flag and the
<B>-all</B> flag.
<P><DT><B><B>-all</B>
</B><DD>Combines the effect of the <B>-bak</B>, <B>-old</B>, and
<B>-core</B> flags. Do not combine this flag with any of those
three.
<P><DT><B><B>-cell</B>
</B><DD>Names the cell in which to run the command. Do not combine this
argument with the <B>-localauth</B> flag. For more details, see the
introductory <B>bos</B> reference page.
<P><DT><B><B>-noauth</B>
</B><DD>Assigns the unprivileged identity <B>anonymous</B> to the
issuer. Do not combine this flag with the <B>-localauth</B>
flag. For more details, see the introductory <B>bos</B> reference
page.
<P><DT><B><B>-localauth</B>
</B><DD>Constructs a server ticket using a key from the local
<B>/usr/afs/etc/KeyFile</B> file. The <B>bos</B> command
interpreter presents the ticket to the BOS Server during mutual
authentication. Do not combine this flag with the <B>-cell</B> or
<B>-noauth</B> options. For more details, see the introductory
<B>bos</B> reference page.
<P><DT><B>-help
</B><DD>Prints the online help for this command. All other valid options
are ignored.
</DL>
<P><STRONG>Examples</STRONG>
<P>The following example removes all files from the <B>/usr/afs/bin</B>
directory on the machine <B>fs3.abc.com</B> that have a
<TT>.BAK</TT> or <TT>.OLD</TT> extension.
<PRE> % <B>bos prune -server fs3.abc.com -bak -old</B>
</PRE>
<P>The following example removes all files from the <B>/usr/afs/bin</B>
directory on the machine <B>db2.abc.com</B> that have a
<TT>.BAK</TT> or <TT>.OLD</TT> extension, and all files from
the <B>/usr/afs/logs</B> directory that have a <TT>core.</TT>
prefix.
<PRE> % <B>bos prune -server db2.abc.com -all</B>
</PRE>
<P><STRONG>Privilege Required</STRONG>
<P>The issuer must be listed in the <B>/usr/afs/etc/UserList</B> file on
the machine named by the <B>-server</B> argument, or must be logged onto a
server machine as the local superuser <B>root</B> if the
<B>-localauth</B> flag is included.
