Thread: Setting up a usage message cmd

Oh, you mean something like this?

Code:

mycmd -h
mycmd --help

You have to make your program output the message you want when the user gives "-h" or "--help" through the command line. There are independent programs that display helpful information, such as "man" for linux.

The simpler implementation for what you want, albeit ad-hoc, is something like the following:

Code:

// Inside a loop
if (strcmp(argv[i], "-h") == 0 || strcmp(argv[i], "--help") == 0) {
    puts("Helpful message!");
}
