A shell is a program that translates text commands (like ls, vim, reboot etc) into instructions for your computer. The default shell on NixOS is bash, but it can be easily changed.
Enable
Always enable the shell, otherwise it wont source the necessary files.
/etc/nixos/configuration.nix
programs.zsh.enable = true;
Changing default shell
Shells can be changed system-wide and per-user. To change the shell system-wide, add the following line to your config:
/etc/nixos/configuration.nix
users.defaultUserShell = pkgs.zsh;
then run nixos-rebuild switch and reboot your system.
To only change the default shell for one of the users, add
/etc/nixos/configuration.nix
users.users.yourname.shell = pkgs.zsh;
