I have used this thruput.awk file and out1.tr is sample file created by la.tcl file .I copy and past trrougput.awk in same folder with la.tcl (give out1.tr file). And the execute the command gawk f throughput1.awk out1.tr. It is wrong method to take awk result of this two files?
Code:

Sorry, it looks like the file was somehow damaged during download or copy/paste or ???. Did you try to modify it by yourself?

"gawk -f"

The hyphen that you are using is wrong . Must be ' - '.

Besides that, no need to copy / paste a file.

Quote:
"awk-and-perl_scripts_11.19.2014" For what pourpose
* Try out the ~20 "throughput scripts" to know if any of those will work with your unknown file.

Usually you cannot just choose a random script from the Internet.
May not work with your trace file.
Hence the choice of ~20 scripts : You may have luck with one or two scripts.
( Besides that, not all trace files may be fit for analyzing.)

You will get ""gawk: ^ invalid char '' in expression""
... until you stop with using forbidden characters in your command.

The hyphen ( - ) that looks like two hyphens (--) is not a valid character.

It shows up here as a 3-em dash, not a minus sign. It's not apparent how you are getting that into a command line, perhaps by cutting and pasting the output from some word processor.

seems like ms-windows copy-pasta:
Code:
gawk f != gawk -f


edit: i am not even sure how you are pasting a dash (instead of a hyphen) into the post. it wont allow me to in this example.

@schneidz : Yes, that's odd.
Some members can type or copy/paste any forbidden character.
My attempts typing or copy/paste from e.g. post #1 are not shown too.

sir.i got results. If it is valid or not?
Code:
[root@localhost ns-allinone-2.34]# gawk -f throughput_newtrace.awk out1.tr
Average Throughput[kbps] = -0.00		 StartTime=400.00	StopTime=0.00
[root@localhost ns-allinone-2.34]# gawk -f Throughput2007.awk out1.tr
Average Throughput[kbps] = -0.00		 StartTime=1000000.00	StopTime=0.00

[root@localhost ns-allinone-2.34]# gawk -f genthroughput.awk out1.tr
Average Throughput[kbps] = -0.00		 StartTime=400.00	StopTime=0.00
Is there any link from where i get parameaters awk file, network life time, energy, througput,scalabiltty,efficiency,Energy Consumption, power consumption and overall network performance,Power Usage of my .tcl file?
