Here is the proper syntax to use the rsh (remote shell) command
without having the remote shell remain active until the remote command is
rsh machine -n 'command >&/dev/null </dev/null &'
where machine is the name of the remote computer and
command is the remote command to be performed.
This works because the -n flag attaches the rsh's
standard input to /dev/null so you can execute the complete
rsh command in the background of the local computer. Also,
the input/output redirections on the remote computer (the stuff inside the
single quotes) makes rsh think the session can be terminated
since there is no data flow. In all truth, you don't have to use
/dev/null. Any filename will work.
