Bluehost doesn’t support Git “out of the box”, but if you have SSH access to your account (if you don’t, just open a support ticket and ask for it. Probably you’ll need to fax or e-mail them your ID card) you can install it yourself.

1. Log into your Bluehost account via the terminal with SSH: ssh youruser@yourdomain.com (you’ll be asked for the password) and you’ll get into your home dir:

Last login: Mon Nov  2 08:34:58 2009 from 253.116.54.71.rev.vodafone.pt
user@domain.pt [~]#

2. Now we need to download the Git software:

user@domain.pt [~]# wget http://kernel.org/pub/software/scm/git/git-1.6.5.2.tar.bz2

This will download the Git package (compressed as tar.bz2) into the home dir of our account (please note that I’m getting the last Git version available at the time of this post but you’ll want the latest one, so make sure to check the filename first on the Git website.

3. Extract the files from the downloaded package:

user@domain.pt [~]# tar -xjvf git-1.6.5.2.tar.bz2

4. Go into the extracted directory and compile Git:

user@domain.pt [~]# cd git-1.6.5.2
user@domain.pt [~]# make

5. This will take a couple of seconds. Then you’ll be ready to install it:

user@domain.pt [~]# make install

And that’s it! You now have Git installed on your Bluehost account!

Now you can type git and hit return and you’ll get the list of the Git commands:
git
usage: git [--version] [--exec-path[=GIT_EXEC_PATH]] [--html-path]
[-p|--paginate|--no-pager]
[--bare] [--git-dir=GIT_DIR] [--work-tree=GIT_WORK_TREE]

Don’t take my word for it. Just try it yourself. Here’s how:

1. Download  a nightly build of Webkit and install it on your machine (don’t worry, it won’t replace your Safari app, it’s a separate app).

2. Launch Terminal and type this on your command line: defaults write com.apple.Safari WebKitDeveloperExtras -bool true

Update: Thanks to Maciej Stachowiak for pointing out the easier way to access the Web Inspector: Just open the Webkit preference menu, go to the Advanced tab and check the “Show Develop menu in menu bar”.

Turn on the Develop Menu in Webkit

3. Open Webkit and load a webpage.

4. Right Click anywhere and choose Inspect Element and voilá…
