Switch bash comparison test image to debian:bookworm-slim#14
Merged
Conversation
bash:5.2 uses Alpine/BusyBox head which lacks GNU long-form flags (--lines=N, --bytes=N, --silent). debian:bookworm-slim is an official Docker image (1B+ pulls) with GNU bash 5.2 and GNU coreutils 9.1, giving byte-for-byte GNU compatibility without BusyBox limitations.
