If the content of X is contained in "Y"

I need to print "Yes" else "No"

Try grep with the -f and if necessary the -v option. Read the man page of grep.

Code:
for i in `cat X`; do grep $i Y; done

Will print all records from file X that exist in Y.

Why exactly do you need a 'cat' there?

Please use the below script:-
copy the script and run them in the unix BASH environment.

count=`wc -l X|cut -d" " -f1`
echo $count
counter=0
for i in `cat X`
do
for j in `cat Y`
do
echo $j | grep $i
if [ $? -eq 0 ]
then
counter=`expr $counter + 1`
fi
done
done
if [ $counter -eq $count ]
then
echo "Both are Same"
else
echo "Both are different"
fi
