https://pubs.opengroup.org/onlinepubs/9699919799/utilities/echo.html echo does not accept options, and is not permitted to accept options including "--". bash does accept -n, -e, -E in violation of POSIX, unless shopt -s shopt -s xpg_echo is set, but it doesn't implement -- and I don't really see a justification to do so. Either enable xpg_echo or use printf. -- Eli Schwartz Arch Linux Bug Wrangler and Trusted User
