shebangs for cross-platform scripts
Shebangs are used to indicate the interpreter to be used to execute a script. They are specific to Unix-like operating systems, and are ignored by Windows. However, you can still use shebangs in cross-platform scripts as a way of providing additional information to developers and tools.
Here are some recommendations for shebangs in cross-platform scripts:
Use a generic shebang that works on both Unix-like and Windows systems, such as
#!/usr/bin/env python
. This will run the script with the Python interpreter found in the current environment.If your script has dependencies that are not installed by default, you can use a specific shebang to indicate which version of Python to use and where to find it. For example,
#!/usr/bin/python3
or#!/usr/local/bin/python3
.For scripts that need to be executed on Windows systems, you can add a comment before the shebang indicating that it should be ignored by Windows. For example,
# This script is intended for Unix-like systems only
, followed by a Unix-like shebang.Alternatively, you can use a separate batch file or PowerShell script to execute the cross-platform script on Windows, instead of relying on shebangs.
