I find the root cause: shouldn't use & after "iftop -nt",because "&" tells bash to fork again.After I test,it's OK.

Hi Paul,
Do you encounter this issue? I haven't found this issue when I used tcpdump. I think it maybe a iftop bug.
Thanks, Darren ------- PS: #!/bin/bash #tcpdump -nnlqp tcp & iftop -nt &
