I usually use listen to save to a file directly. You can create a new file listen > file.log or append listen >> file.log then use your favorite scripting language (or any other language) to parse the data and save a file for each mote. You could even use grep to sort out the data manually. I have used perl scripts by piping "|" the data from listen into the script. listen | perlscript.pl you can save it as a file listen | perlscript.pl > file.log and even monitor it listen | perlscript.pl | tee file.log It is much easier to process the data afterward then to try to rewrite a program, and you can choose how you do it. -- The difference between the right word and the almost right word is really a large matter- it's the difference between a lightning bug and the lightning. -Twain _______________________________________________ Tinyos-help mailing list [email protected] https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
