[Wrapper-user] Shell script won't execute on Mac

[Mark L. <mid...@ve...>]

I was able to get Wrapper running on Windows in about 10 minutes, but 3 
hours so far trying to make it work with the Mac have been fruitless. 
The problem is simple. I copied script.sh.in to my app's /bin directory, 
renamed it RCBServer (my app name), set its file mode to 774, edited the 
app name variable settings as directed in the instructions, and made 
sure to save the script file with Unix line breaks. But when I type 
"RCBServer" from the bin directory that contains the script file with 
that name, I get the error message "Command not found."  I can run shell 
scripts anywhere else on my Mac in this fashion, but this one just won't 
run for some reason. I must be missing something really basic, but it's 
obviously not going to occur to me without help.
