Please guide me.

Exactly what guidance are you looking for?

Are you saying you have looked through the manual and none of what is contained in the script makes sense?

"energy_wireless.awk" is an "awk script for ns2 trace files".

Using, example : $ ns wireless-flooding.tcl
.. will create the trace file "wireless-flooding-DumbAgent.tr"
Code:
$ awk -f energy_wireless.awk wireless-flooding-DumbAgent.tr                                       
No of pkts send                43

Do you mean a shell script / bash script ? And which one ?

Well I see nothing from the original script that is very hard to understand assuming you have read the manual.

In case you had trouble using google or any other search engine to find one:

After reading the manual, please advise which part you are confused about?

Not sure what a ".tr" is, but as you are asking the question it would be up to you to provide what it is you do not understand and to actually ask a clear question.
