I was surprised actually when I got the above mentioned bug because I had have always been giving only one argument, when I wanted the "command" to be executed on the shell. Anyway, the problem was actually solved when I stored the output of the above "command" in a text file (rx_ack_log.txt) as follows: command = 'python send.py -d %d -s %d -c %d -n %d -f trash_file.txt >> rx_ack_log.txt' %(dest_addr, sender_addr, cmd, seqno) os.popen(command) thanks for the help! regards, -Sumit _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
