I was using Terminal just now and realized that I was seeing something different on the screen than I have in the past. I can't remember what it used to be, but I know for a FACT that I have never seen "integrativeasheville:~" in Terminal. What is going on?

integrativeasheville:~ pbishop$ pwd
/Users/pbishop
integrativeasheville:~ pbishop$ whoami
pbishop
integrativeasheville:~ pbishop$ hostname
integrativeasheville.us8.list
Just open up terminal, go to the preferences and select the theme (the .terminal file)
Here's what happened. On the machines I was trying to reach (10.x.y.182 and 10.x.y.194), in the time when I was not using them they had their hard disks replaced and the OS reinstalled. This gave them new SSH keys, invalidating the ones I had in my ~/.ssh/known_hosts file. Unfortunately, Terminal.app did not surface this problem to me.
By deleting the entries for those machines in ~/.ssh/known_hosts, I forced the system to pull down the new keys and ask me if I wanted to use them. With this done, connections worked perfectly as usual. Oddly, however, even before I changed ~/.ssh/known_hosts, connections using the DNS name of the machine (svr10 and svr20) worked. Weird.
Thanks, everyone, who looked at this problem.

This:
is called the shell prompt. It's presented to you when you open a shell in a Terminal window and it can be customized. Some people like their prompts to show lots of information like the hostname their currently logged in to, the user they're running as, the current directory they're, etc. For example, I like:
That's a two-line prompt that shows me the directory, the version of Ruby loaded by RVM and the gem bundle as well as the git branch I'm working on and the clean/dirty state of the local repository.
The prompt is completely customizable via
PS1environment variable inbash(the default shell in OS X). Out of the box, OS X hasPS1set to:This says: "display the host name, followed by a colon, then the current working directory followed by a space and then the name of the user and the default prompt character."
For a standard user this evaluates to something like:
As you can see, my prompt looks an awful lot like your prompt when I use
bash(I usezshby default in my environment so I had to switch tobashto show this to you).That is to say, in a very long winded way: your prompt looks exactly like the default OS X
bashprompt. Nothing odd about it all.The
integrativeashevillepart is your machine's host name. the:is just a separator. And the~means you're in your home directory --~is shorthand for "my home directory" in shell path language.
