How would I write a script for the scriptfile "puzzlescript" to make the gotchascript echo back "gotcha" ? The idea here is to set up the first script named gotcha so that when $sum and $rightsum are equal the script will echo back gotcha. It is set up to look at and execute the scriptfile 'puzzlescript' to see if its value is equal to $rightsum. Puzzlescript is set up in another part of the directory and has to be written in such a way that when the gotchascript comes to run it, it triggers the echo gotcha from the gotchascript.
if [ ~/puzzle ]
sum=` ~/puzzle 5 10 20 $$`
rightsum=`expr 35 + $$`
if [ $sum -eq $rightsum ]
What I've come up with so far is,
sum=`expr 5 + 10 + 20 + $$`
but it won't cause the echo gotcha from the gotchascript
