Hi Bjoern, Thanks for the info and the fix.
So far we had no issues but it's not extensive testing. I'll let you know if it fails for some reason. In addition to the shebang change we also started using "perl script" instead of simply "script". Since "perl" is looked up in PATH, all else works as expected. It does get a bit tricky if you need to guess where the script is located. "$(which script)" works but it's hacky. Still, it's the only way you can "fix" the shebang without changing it before. PS: There's shutil.which() but only python 3.3 onwards.
