Step-by-step guide

Open Terminal or establish a SSH session if performing this remotely: 

1. Check and note your current login shell 

   echo $SHELL
   /bin/bash

2. To change your shell, create a ~/.bash_profile in the root of your home directory with the following lines or if you already have a .bash_profile append it with the below entries.  This example is for zsh.

   export SHELL=/bin/zsh
   exec zsh
