Firstly thank you so much for attending my question.

I want to say that i do not understand too much from awk / gawk and mawk i have a script that i downloaded from the internet . It returns me some output about getting too much traffic ip addresses.and gives an out put as :

Time IP xxxMbps
Time IP xxxpps
Time IP xxxpps
Time IP xxxMbps
Time IP xxxpps



but this is just for src_ip side.
i want also to get dst_ip and add one more expression to it like that


Time IP xxxMbps   in
Time IP xxxpps   in
Time IP xxxpps  out
Time IP xxxMbps in
Time IP xxxpps out


how should i do this ?

# for performance reasons, mawk is preferred to gawk
# newer versions of mawk include things like strftime that tradionally had been
# gawk-only features. code and builds of mawk-cur (cutting edge) can be found at:
#    http://invisible-island.net/mawk/
# (the features of mawk-cur aren't available in official debian packages of mawk)
