Answer 1

Yes, with syntax issues fixed

That almost worked. The correct syntax is:

counter=`ps -ef | grep -c "myApplication"`; if [ $counter -eq 1 ]; then echo "true"; fi

But note that in an expression of this sort involving ps and grep, the grep will usually match itself because the characters "grep -c Myapplication" show up in the ps listing. There are several ways around that, one of them is to grep for something like [M]yapplication.
