Do this..you should get what you want..

while read line
do
filefound=`grep -l $line file2 file3 file4 file5 file6 file7`
output=`echo $filefound | cut -d: -f1`

Y788O
T347U
J23U

b:
file2 J23U U887Y I99U T556U
file3 I99O J99T F557J
file4 N99I T666U R55Y
file5 H87I T347U
file6 H77U R556Y E44T
file7 Y788O K98U H8I

code:

Code:

awk '
{
if (NF==1)
	a[$1]=$1
else
	for (i in a)
		if($2==a[i])
			a[i]=$1
}
END{
for (i in a)
print i " "a[i]
}' a b

output:

Code:
