several.

1] have a different script for each 'remote' on server, where in the
remote's script does not include itself. then shutdown 'remote' being
used manually.

2] have an "if not" condition which tests to see which 'remote' is calling
script. this way, 'remote' would be skipped and can be shutdown mannually.

3] have a script that runs from each 'remote' for shutting down other
remotes and run it in background with a shutdown after it runs.

if you want a time delay, use "-t xx" where 'xx' = time delay in seconds.

if you use "&", add a space between last of command and "&".
