The open group changed their website stupidly, so opengroup.org/onlinepubs forwards to a dead server and you have to use pubs.opengroup.org/onlinepubs now. Change the hello template to note the new location. (Waiting to see if they fix it upstream before touching every command in toys/posix.)

    A hello world program.  You don't need this.

    Mostly used as an example/skeleton file for adding new commands,
    occasionally nice to test kernel booting via "init=/bin/hello".
