Many people uses awk in their shell script, but they need to pass variable to awk for manipulation, it is not difficult, bellow is a simple example.
awk 'END { print myval }' myval=`pwd` data.txtThis example is to show you, I successfully pass a value from outside, at the END of the manipulation, print me my value I pass in. You can specified any variable name, for this case i uses “myval”.
If you define your awk rules in a file, you can do that as bellow to pass in variables.
awk -f bandwidth.awk measurement="kbps" proto="tcp" pcap.tr
