How to append using sed

Hello all,

I want to use sed to append a variable stored in $i, how do i do that?
$i contains a path to a directory and i want to append it before the result i get from awk statement, before affecting awk results.

rite now out put i get from code below is:-

The path is: /net/icebox/vol/local_images/spins/7.1/CQ/7.1.D081110/
basement.sun5 
msgcat.JPN.sun5
perl.sun5
CMServer.CQ.sun5

Output desired:-

The path is: /net/icebox/vol/local_images/spins/7.1/CQ/7.1.D081110/
basement.sun5   /net/icebox/vol/local_images/spins/7.1/CQ/7.1.D081110/
msgcat.JPN.sun5  /net/icebox/vol/local_images/spins/7.1/CQ/7.1.D081110/ 
perl.sun5  /net/icebox/vol/local_images/spins/7.1/CQ/7.1.D081110/ 
CMServer.CQ.sun5   /net/icebox/vol/local_images/spins/7.1/CQ/7.1.D081110/
check_sun() {
for i in $SUN_PLATFORM
do
$ECHO "The path is: " $i
$LS $i | $GREP .su |  $AWK -F"_" '{print $1}'
done
}

Thanks

$LS $i | $GREP .su |  $AWK -F"_" '{print $1, path}' path="${i}"
