Nope! The awk redirection is different from the shell redirection Smilie
I would suggest reading Effective AWK Programming (it's free):

sorry radoulov, I don't have "nawk" in my system so I didn't try it. But it works perfectly fine in presence and absence of "$0" as you mentioned for "awk". Sorry for my wrong comment posted earlier. But can you answer me for my question regarding checking of the value like 40, 46 .. etc.,? I will definitely go through the PDF document.

It doesn't check anything: $2 is variable (so the filename to append varies),
it changes with the record, so if the record's second field is 40,
it goes to file named "ss"$2".sh" -> "ss"40".sh".

P.S. Feel free to correct my englishSmilie HTH.

Just beat me to it! Was going to give almost exactly the same answer. BTW, since you said to correct your English, I did fix a spelling mistake in your post. Hope you don't mind. Smilie

Yes, got the essence after reading the PDF "regarding redirection & print with no arguments", thanks a lot radoulov. You're awesome :-)

For the sake of clarity for the other users, I am posting the excerpt taken from the PDF that cleared my doubts (note: I just edited a bit)

The simple statement 'print' with no items is equivalent to 'print $0', it prints the entire current record. When '>' type of redirection is used in print eg: print val > file, the output file is erased before the first output is written to it. Subsequent writes to the same output file do not erase the file, but append to it. This is different from how you use redirections in shell scripts.
