Setting hostname on a mac

Setting hostname on a mac

With all the machines I now use, and the fact I’m getting older and my memory is going, I needed to add hostname into my bash prompt for the first time, and came across a little issue on Apple’s Mac OS X Mountain Lion.

When I updated my PS1 setting I was getting:

```
(null):~
```

Not so good. I was also getting similar responses when I was running “hostname” on the command line.

I’ve now found out how to resolve this issue on Mountain Lion:

```
$ sudo scutil --set HostName [Your Hostname]
```

This will now allow you to use “\h” in your PS1 setting and give you the correct result when running “hostname”
