[Tinyos-help] Multiple SerialForwarders and Listeners

[Michael Schippling]

Assuming you actually got all the SF's to run on the right ports,
you can use an "&" at the end of the line to put the command
"in the background" so you can execute more commands while it is
running:    some -command -with -args &

If you have a bunch of commands in a file, again with the "&"'s
and redirect that script file output, it should also redirect
the individual command outputs. However it may not interleave
lines in a clean way...that's system and luck dependent.

For details of how to use the bash shell try:
	help bash
or
	man bash
