I have configured Terminal’s style as Homebrew but it’s only used for the first window if Terminal is launched. If I type the shortcut Command+N the new window has the basic style which I don’t like, it’s just white so not really stylish. I knew that defaults exist to modify an application’s settings using a shell.
defaults read com.apple.Terminal
If you type this in your shell you get the settings set for your application, in my case for Terminal. I was interested in the entry “Default Window Settings”. The value of this key was Basic though I have explicity set it to Homebrew in the configuration panel.
defaults write com.apple.Terminal "Default Window Settings" Homebrew
This line affects the style permantly. Restart Terminal to read the new settings and enjoy the new style.
