Code:
cat temp.txt

mqsiaaa 123 888
mqsiddd 456 999
t2589gg 789 555

and

Code:
awk '$2~/456/ { printf $3 > "filefilter"}' temp.txt

   #The expected output is correct:

cat filefilter
999

Same can be said if you use a variable:
Code:
var=`awk '$2~/456/ { printf $3 }' temp.txt`
echo $var
999

---------------------------------------------------------
Thanks a lot man !!

Could you please check following way of writing awk is correct or not ???

-----------------------------------------------------------

pattern= "mqsi[admtspr]"

cat tempgrep.txt | \
while read ppid
do
awk '{
recurcive_fun(ppid, pattern)
function recurcive_fun(n, pattern)
{
awk '{ if ($2~n && $1~pattern){
n=$3
recurcive_fun(n, pattern)}
else{
if ($2~n && $1!~pettern){
print $1 >> "tempmail.txt"
exit
}
else {next}
}
}' tempfind.txt
}
}'

done
-----------------------------------------------------------------

Its recursion being called.

tempgrep.txt has :
462948
1311040
880922

tempfind.txt has :
t2589vg 880922 462948 09:57:07 -ksh
mqsiadm 1298856 1311040 09:57:56 -ksh
mqsiadm 1311040 880922 09:57:19 -ksh

Please suggust !!
Thanks
