Programming Elixir 1.6: Inaccurate terminal command (page 150)
The terminal command to run the function on page 150 of Transformation: Fetch from GitHub section is -
mix run -e 'Issues.CLI.run(["-h"])'
This command doesn’t return anything. The correct command is -
mix run -e "Issues.CLI.run(["-h"])"
