Oh, then only warn when set +o posix and shopt -u compat_im_too_lazy_to_fix_backticks is in effect! (Insert large tongue-in-cheek smiley) Seriously though, the internet is awash with "helpful" Shell guides and examples loaded with poor practices. The only way this is going to improve is if there's a "linting mode" is included in the Shell and on by default. Consider this a feature request for a linting mode, on when invoked with bash -n or bash6. -Martin
