This demonstrates shims for 2 features that are missing from Batsh.

  • An ugly way to get script arguments.
  • A polyglot build option.

The polyglot is created by copying the output of the respective compiles into template.bat
The example script launches a program not found in $PATH (sublime text).
The final script polygot_argument_launch_compiled.bat can be launched from both git-bash and cmd.exe with a filename argument.

Compiled using http://batsh.org/

template.bat was found at:
