While i pipe nethogs it takes too much delay for the output ( About 5-200 sec instead of 1 sec depend on pipe,cmd etc). Nethogs print output in every second.
For the sake of simplicity consider the following command ( it takes abt 5 sec )
sudo nethogs ppp0 | grep e | grep e |grep c
I belive it due to the buffering in pipe.
How can i avoid the delay (In general or in the case of nethogs)???
