Well..
You can do this:

function getthree() {
mfn=$1
fn=$2
out=`awk -v fn=$fn ' {
if ($3) {
print $3 ; print $3 >> fn
close(fn)
}
}' $mfn`
test ! -z $out && export out && return $?
}
Now all you have to do is call;
getthree filename tmpfilename

YMMV

Good Luck

hi marsd,
thx for your reply.. am new to scripting and 've never used a function call.. can u pls explain me how do u call this fn ? and can u explain this line
getthree filename tmpfilename ( i know this is the call to the function.. but dont know whats that tmpfilename and filename... ur help appreciated...

To use the function, call it as written at the point in your script where you would do your awk {print $3}, etc.. line

The first parameter is the name of the file you wish awk to read from,the second parameter is the tmpfile you want
results written to. The result of reading field three is
exported into your shell global environment if not empty and can be accessed as the variable out:ex: echo $out.

ex:
getthree /home/myfile /home/tmp.out
echo $out

do you realy have to do that with awk?

while read xx
do
set $xx
if [ -n "$3" ] ;then
echo $3
fi
done < files.txt >> ./tmp5

can you do it like this?

Do you really have to do it with the shell?
Did the OP ask for a shell solution?

I don't know. I don't even work here.
