Motivation
For me
nob.cis more than a test suite, it's an example for users ofnob.h, as this double slash feature is underappreciated it would be great to share this to the users.Where it works
This should only work with an
envexecutable that is located in/usr/binand supports the-Sflag on OSes that support the double forward slash as a shebang (This feature is implemented on recent Linux kernels). On other cases this should be ignored as a comment or cause an indecipherable error.How the shebang works
Upon execution the Kernel Program Loader will parse the double slash and find the program starting from the root directory, if found it will execute it, the rest of the work is on
envthat parses the executed line and create a valid command to pass to the shell.Sorry if something on this explanation is missing, I did this PR in a hurry.
