Help needed in awk

Rahul_13 — Tue, 18 Nov 2003 15:13:38 GMT

Hi,

I have few log files like:

handler_5620_15:09:48.log
handler_566_14:31:07.log
handler_7995_15:28:39.log

and more...

I have to extract the portion till the second underscore (till handler_5620) for all the logs. I know how to accomplish this in SHELL script. But I have to do this using AWK.

Can anyone please help me out in this problem.

Thanks,
Rahul

ls -1 | while read FN
do
echo $FN | awk -F_ '{print $1 "_" $2}'
done

will put the "_" back in the ouptput string..
