MacOS login shell

Configure the terminal to run your shell as a login shell

The stock shell configuration examples for Pyenv 2.0.0-2.2.5 for MacOS assume that the shell in the terminal runs as a login shell.

Check if the current shell is a login shell

• Bash:

  shopt -q login_shell && echo 'Login shell' || echo 'Not login shell'

• Zsh:

  if [[ -o login ]]; then echo "login shell"; else echo "not login shell"; fi

• Fish:

  status --is-login; and echo "login shell"; or echo "not login shell"

Set the shell to run as a login shell

There are two possible ways here.

Set the shell as your login shell (recommended)

• System Preferences > Users and groups > Open the padlock to allow changes > Right click on the corresponding user's name > Advanced options > Select the shell from the dropdown list next to Login shell

  • Alternatively, in the terminal: chsh -s <shell>

• Then, in the Terminal app: Preferences > General > Open shells with > Predefined login shell

Configure the terminal to explicitly run a shell as a login shell

• In the Terminal app: Preferences > General > Open shells with > Command (full path)

  • Zsh: /bin/zsh --login
  • Bash: /bin/bash -l
  • Fish: <path to fish executable> --login
