This is the correct way to begin python scripts (I can't say how the perl community feels) : #!/usr/bin/env python # python code here The idea is that env knows where stuff on the current machine is, so simply ask it for the interperter you want (python, perl, bash, etc). On a tangent, is there a way to manually configure env as to program locations? In particular, how can I have env on my cygwin installation know where python is (Win32 python build)? For now I have my python script in foo.py with a wrapper foo that does : #!/bin/bash python foo.py $* -D
