Terminal Customization

How to improve default terminal experience

Hostname in Terminal

By default, the Terminal app will display your [email protected].

• We can change the hostname by going to System Settings > General > About but this still leaves .local appended within the Terminal

• So instead we can run this command sudo scutil --set HostName <new_hostname>
