Hi, if I *not install*
nix-env -i bash and I execute the command nix-shell '<nixpkgs>' -A hello I don't enter into a nix-shell environment, but there is no error message, and also echo $? 0 signals that it is all ok. But this is not the case, because the nix-shell never started: the prompt remain the normal prompt, and not the nix-shell special prompt. So this is a bad behaviour of nix-shell that at least must signal an error message. On the contrary if I * first install* nix-env -i bash then nix-shell '<nixpkgs>' -A hello starts correctly, also if I'm calling it from the native bash of Mint, and not from the bash of Nix. Probably nix-shell calls the bash of Nix, and in this case it finds it because I installed it. I'm probably in a strange case respect normal Nix usage, because I start as normal user, with no Nix profile installed. So the bash shell is always the bash of Mint in my case. A work-around is inserting into the installation manual/wiki, the suggested command nix-env -i bash so all nix-shell commands will work as expected. Can be a proper analysis of the problem?
