> When using the `sleep` command with the end-of-options delimiter `--` (that is, `sleep -- 1` or `busybox sleep -- 1`), the command fails to execute properly. However, both `sleep 1` and `busybox sleep 1` commands work as expected. According to the POSIX standard, both constructions should be permitted.
