Hostname has changed in Terminal

Never seen this before in all my years using a Mac.  Today I loaded terminal and instead of saying “Craig’s MacBook Air” it said the prompt was Mums iPhone.

This seems very strange as I know the kids or the wife would not know how to do it.  When I typed hostname from the prompt, again it was showing Mums iPhone. 

It seemed it was not changed everywhere in /Library/Preferences/SystemConfiguration/preferences.plist it was still showing as Craig’s MacBook Air. 

Nice simple fix, from the terminal prompt type the following

scutil --set HostName "Craig’s MacBook Air"

Then open a new session and you should be back to normal.
