Mac Terminal shows the name of a network machine on the prompt

Question

Once I launch the terminal app, I see a network machine name before my name, any idea how to fix it.

attached screenshot.

the name before : (colon) is a network machine name

Edit:

i went to system preferences and turned off file sharing, but it's still there (will check again after rebooting computer)

Answer 1

This has nothing to do with FileSharing and everything to do with the hostname that the DNS server (usually a dynamic address-ing DHCP thing) assigns you.

So what you really want to do is modify your Bash prompt.

And here is a tutorial that talks about how to do it.
