One way is to sit in a sleep loop.

Code:
while true
do
        if [ -f A.txt ]
        then
                sleep 10
        else
                break
        fi
done
b.sh

avronius is right. Unless the file is a simple flag created with something like "touch" it could be not ready for processing.
