I was wondering if anyone could explain the meaning the command below in mac terminal:

dhcp-74-148:~

Noticed it for the first time today and just wondering what it meant.

Thanks

That line is called command prompt.

dhcp-74-148 is you hostname that you received from dhcp server.

~ is where you currently are (which directory) - tilda means you are in your home folder, /Users/[username]

: just separates hostname from current directory.

You can change format of command prompt by changing $PS1 variable. And - if you're interested - check out some bash shell tutorial for more information.

  • thanks for that answer. I"ll read more about the shell. I just noticed that command for the first time when I opened the terminal today-I've used the terminal before but it was a different command that was there. Still trying to figure out exactly what was there previously. – John_dydx Nov 17 '14 at 15:07
  • You should be able to change it going to System Preferences > Sharing > Computer Name. It will also be name of your machine others will see if you will share some files or use AirDrop. – Marek Bettman Nov 17 '14 at 15:09
  • As for changing the prompt - if - for example - you do export PS1='[\033[01;34m]\t [\033[01;32m]\u@\h [\033[01;34m]\w $[\033[00m]', you will have nice green/blue prompt with username and time :) – Marek Bettman Nov 17 '14 at 15:11
