package: busybox version: 1.36.1 Bug description: 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.
Minimal steps to reproduce: $ docker pull alpine $ docker run -it alpine $ busybox --help | head -1 BusyBox v1.36.1 (2023-06-02 00:42:02 UTC) multi-call binary. $ cat /etc/os-release NAME="Alpine Linux" ID=alpine VERSION_ID=3.18.2 PRETTY_NAME="Alpine Linux v3.18" HOME_URL="https://alpinelinux.org/"; BUG_REPORT_URL="https://gitlab.alpinelinux.org/alpine/aports/-/issues"; $ *sleep 1* # sleeps for a second $ *sleep -- 1* sh: invalid number '--' # and container exits $ busybox sleep 1 # sleeps for a second $ *busybox sleep -- 1* *sleep: invalid number '--'* # container does not exit $ apk add coreutils # install coreutils on Alpine Linux $ *coreutils --coreutils-prog=sleep 1* # sleeps for a second $ *coreutils --coreutils-prog=sleep -- 1* # also sleeps for a second Thank you, Lucas Larson
