Still don’t do this. If you use bash specific syntax with this head, that’s a bashism and causes issues with people using zsh for example. Or with Debian/*buntu, who use dash as init shell.
Just use #!/bin/bash or #!/usr/bin/env bash if you’re funny.
#!/bin/bash doesn’t work on NixOS since bash is in the nix store somewhere, #!/usr/bin/env bash resolves the correct location regardless of where bash is
I do think a simple symlink is superior to a tool parsing stuff. A shame POSIX choose this approach.
Still the issue that a posix shell can be on a non-posix system and vice versa. And certificates versus used practice. Btw, isn’t there only one posix certified Linux distro? Was it Suse?
