Shell Programming and Scripting

Thanks . it is working but i have one problem

sometimes $1 $2 doesnt match with $4 $5
i want to print those rows also in table format .

can i do that
it may happen some test cases doesnt run on that day
so i want to print blank on that

i am printing format like this
Vers Host Fails date Fails date2
10 Test1 30 24
10 Test2 34 67
11 Test1 65
11 Test2 65


Please help me

Put this code in a shell script
For eg. test_script.sh

file1=$1
file2=$2

while read a b c
do
v1=$a$b
lp="$a $b $c"
while read x y z
do
v2=$x$y
if [ $v1 = $v2 ]
then
lp="$lp $z"

fi
done < $file2
echo $lp

done < $file1

Then run the shell script
For eg. test_script.sh yourfile1 yourfile2

rajeeb_d,
you've missed the point:

Code:

FNR==NR { arr[$1 OFS $2]=$3; next }
{
   idx=$1 OFS $2
   printf("%s\n", (idx in arr) ? idx OFS arr[idx] OFS $3 : $0)
}

how come we have such a similar problem ?
