Use the same Mathematica Executable Script on Different Computers

Question

The first line in a Mathematica executable script specifies the directory of WolframScript, e.g.

#!/usr/local/bin/WolframScript -script

Assume I want to run a Mathematica executable script on two different computers, with different directories of WolframScript. This means running the script on the first computer requires the first line to be e.g.

#!/usr/local/bin/WolframScript -script

while on the other computer the first line needs to be (say)

#!/usr/opt/mathematica/bin/WolframScript -script

How can I write the Mathematica exectubale script so that it runs on both computers without changing the first line?

Answer 1

I'm not on Unix but Windows but you should be able to do this. Booting up mac to test.

#!/usr/bin/env WolframScript
