<P><STRONG>Description</STRONG>
<P>The <B>bos exec</B> command executes the indicated command on the file
server machine named by the <B>-server</B> argument. Its intended
use is to reboot the machine, using the <B>/etc/reboot</B> command or
equivalent.
<P><STRONG>Options</STRONG>
<DL>
<P><DT><B><B>-server</B>
</B><DD>Indicates the server machine on which to execute the command.
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>-cmd</B>
</B><DD>Specifies the complete local disk pathname of the command to execute (for
example, <B>/etc/reboot</B>). Surround this argument with double
quotes ("") if the command contains one or more spaces.
<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 command reboots the machine
<B>fs2.abc.com</B>. The issuer has previously issued
the <B>bos shutdown</B> command to shutdown all processes cleanly.
<PRE> % <B>bos exec -server fs2.abc.com -cmd /sbin/shutdown -r now</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.
