sh is running the while loop in a subshell. Variables changed in the subshell do affect the values in the main shell.

ksh won't do that. Switch to ksh.

And ksh can increment the variable directly:
((test=test+1))

I'm not familiar with MOSX, but you have an odd version of sh if that script really runs.

You will probably need to switch the == to just = (or -eq) in your if statement. And I'm not sure why you're checking the exit code from the echo statement anyway. Are you actually finding filenames that your echo command cannot output?
