Hi Don, also if you see that file4 content, i am putting field1 in array whose value is field2 from file4
Code:
filecounter==4{UPW[$1]=$2;next}

& the same is being matched from mainfile. I have also highlighted the same in my earlier post. Can you please suggest how to handle this.
I understand that your code is setting values in your four arrays that are never used. If you change the four lines setting the arrays from:
Code:
filecounter==1 {KRL[$1]=$2;next}
...

to:
Code:
filecounter==1 {KRL[$1];next}
...

you would get exactly the same results. I left that seemingly extraneous initialization in place assuming that your real code would do something with the values that had been saved in the arrays instead of just saying "FOUND IN arrayname".

But I have no idea what "this" is referring to in:

Code:
awk 'END{print(NR>2)?"NOT EMPTY":"EMPTY"}'

You must put this part in END block otherwise it'll be executed for every line.
I do not see how this is related to this thread??? Adding this END clause to the code being used in this thread will print "NOT EMPTY" if at least one of the five files being processed by these scripts is not empty, and will print "EMPTY" if there are no lines in any of the five input files.

Sorry, I should have gotten more sleep last night. Ignore what I said above...
