Question

I searched google but couldn’t find an answer to this rather simple question. I have a python script that has the hash-bang (#!) on the first line:

#!/usr/bin/python 

However, what if this is run on a computer with python in /bin/python or /usr/local/bin/python, or some other place? There has to be a better way to set the interpreter for a shell script. It should be possible to set it via $PATH, as that will know where to find python if it’s installed on the system.

Answer 1

Use env.

#!/usr/bin/env python 

It’s not bulletproof, but it covers more cases than /usr/bin/python.
