Bash

Bash (Bourne Again SHell) is the default command-line shell on many Linux systems, including NixOS.

Installation

Configuration

NixOS System Configuration

Bash can be configured system-wide using the programs.bash module in your configuration.nix. Below is an example configuration:

❄︎ /etc/nixos/configuration.nix

programs.bash = {
  shellAliases = {
    ll = "ls -l";
    rebuild = "sudo nixos-rebuild switch";
  };
};

For a complete list of available options, see programs.bash.
