Examples

  • Start a shell providing youtube-dl from the nixpkgs flake:

    # nix shell nixpkgs#youtube-dl
    # youtube-dl --version
    2020.11.01.1
    
  • Start a shell providing GNU Hello from NixOS 20.03:

    # nix shell nixpkgs/nixos-20.03#hello
    
  • Run GNU Hello:

    # nix shell nixpkgs#hello -c hello --greeting 'Hi everybody!'
    Hi everybody!
    
  • Run multiple commands in a shell environment:

    # nix shell nixpkgs#gnumake -c sh -c "cd src && make"
    
  • Run GNU Hello in a chroot store:

    # nix shell --store ~/my-nix nixpkgs#hello -c hello
    
  • Start a shell providing GNU Hello in a chroot store:

    # nix shell --store ~/my-nix nixpkgs#hello nixpkgs#bashInteractive -c bash
    

    Note that it's necessary to specify bash explicitly because your default shell (e.g. /bin/bash) generally will not exist in the chroot.

Description

nix shell runs a command in an environment in which the $PATH variable provides the specified installables. If no command is specified, it starts the default shell of your user account specified by $SHELL.
