This is why I tend to stick to POSIX shell scripting these days, avoiding even bash. The restriction does make some things too painful, though. Before the latest POSIX revision, certain workflows were comically hard to do (unless you combine sh with... M4). The 2024 revision injects some much-needed sanity, but I am wondering, will random computers have shells compliant with that revision?
