Terminal shows iPhone instead of MacBook Pro

Question

I'm relatively new to Mac, but otherwise computer literate.  Have had occasion to go into Terminal to try to execute a couple of commands, but... everytime I open Terminal, it shows iPhone as the computer name instead of my MacBook Pro.  I haven't connected an iPhone to this MacBook in months (and in fact I no longer even own that iPhone).  How did this get changed, and more importantly, how can I change it back to the proper path?

Answer 1

The 'bash' shell does a reverse DNS lookup on your IP address, and then displays that as your computer name.  If no external DNS server responds, then the Mac will use the name in System Preferences -> Sharing
So there is a good chance your home router is your local DNS server, and it has associated your IP address with your iPhone, and is returning that name when 'bash' ask what name is associated with your IP address.
You can ignore this if you want.  It is harmless.
You can try beating up your home router for being stupid.
You can create a 'bash' initialization file and specify your own prompt
nano ~/.bash_profile
PS1="$(networksetup -getcomputername):\W \u\$ "
which will always return your System Preferences -> Sharing computer name
