Over the last few years I’ve released a number of command line utilities for macOS. I’ve always included online help within them, triggered with the --help switch, but I recently wondered how I might provide Unix Manual pages too. It would allow users to call up help with the CLI command man as well as a command switch. Belts and braces, perhaps, but I’m a completist and, more to the point, didn’t know how it was done and wanted to learn.
