So I'm in terminal and run the following:
svradmin$ ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"

-----------------------------
And get the following error message:
It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:
    rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

------------------------------
So I copy and paste the above and get the following error message:
-bash: m: command not found

I've found this great web url that addresses this but I'm concerned about trying some of the stuff:
https://github.com/mxcl/homebrew/issues/14319
--------------------------------

One of which is to delete /usr/local when I know I have MySQL installed already there.
-----------------------------

I've also tried this step by step process in Terminal and it obviously didn't work:
http://superuser.com/questions/203707/how-to-uninstall-homebrew-osx-package-manager
------------------------------


So my question is - How do I uninstall homebrew with this situation?

Thank you for any replies.  I do have more questions and will break out such in further posts!  Please be patient with me in having this question this way for now.

Generic commands like "delete /usr/local" are very dangerous.  The underlying system for Macs was based on FreeBSD, a version of Unix.  The Mac OSX operating system hides a lot of that to make a system that is easy for non-technical users to operate.  Mostly.  If you are going to start working in 'terminal' on the command line, you will have to learn the Unix commands for viewing and doing things.  'usr/local' will never appear in Finder.

Here's some history and basic info to help you: http://www.mac-guides-and-solutions.com/mac-unix.html

I'm sorry if you read what I had before I edited.  Tried to keep it as one question.
I still need exact help on uninstalling HomeBrew.

As regards your statement that usr/local will never appear in Finder.
It does and once you open Finder - you go to Go at the Top - select Go To Finder and then type /usr - that folder and all the subs appear.

Again need some help with uninstalling HomeBrew!  Any comments towards that will be appreciated!

I've never dealt with Homebrew so I can't help you there.  But with some of the things you have posted, I think you need to make a complete backup before you proceed.  I would hate to lose everything I've installed because of instructions like that.

Good info on Finder though, I had never tried that.

I read the post more closely (https://github.com/mxcl/homebrew/issues/14319) and this had worked (without deleting the /urs/local folder)

cd /usr/local && /bin/bash -o pipefail -c '/usr/bin/curl -skSfL https://github.com/mxcl/homebrew/tarball/master | /usr/bin/tar xz -m --strip 1'
