I had problems with colours not showing in iTerm2 for me. I tried a few fixes I found online which didn't work and now my serial number of my laptop is showing in iTerm & Terminal. Anyone know how to remove this?

  • If you shut down and restart - this could be temporary. If not, type hostname, did you or your network name your machine with your serial number? If so, do you want to change the name entirely or just that prompt?

You want to modify something called the prompt or PS1. You can see the current value by typing echo $PS1 To get rid of the first part you don't like and leave only the user name type export PS1="\u" If you want to persist the next time you open the terminal, you would write that line in ~/.bashrc A detailed walk through is here http://osxdaily.com/2006/12/11/how-to-customize-your-terminal-prompt/
