Nix sometimes outputs a warning message like this: ``` directory /nix does not exist; creating it by running ‘?? using sudo ``` ... when it really meant to output something that looked like this: ``` directory /nix does not exist; creating it by running 'mkdir -m 0755 /nix && chown gabriel /nix' using sudo ``` The reason why is due to some bizarre behavior in Bash where it will translate anything of the form `$x’` to `??`, leading to the incorrect warning message. I don't know what is the origin of this Bash behavior, but the easiest fix is to just use ASCII quotes instead of unicode quotes.
