Thanks for your quick reply... I have fixed the problem

Here the working code snippet

REQUEST_ID="1234"
X=`echo "$REQUEST_ID" | awk '$0 ~/[^0-9]/ { print "NOT_NUMBER" }'`
echo "Request Id: $REQUEST_ID"
echo "TEST :::$X"

if [ "$REQUEST_ID" != "" ] && [ "$X" != "NOT_NUMBER" ]; then
echo "Its number......"
else
echo "Not an number"
fi

Regards
BS
