How to find which git branch I am on when my disk is mounted on other server
GitGit BranchGit Problem Overview
Our git repo is on a Linux server; I can be on the master branch or create a new branch that I can go inside and use.
Our git repo disk is mounted on AIX box to build (I can see git directory in the AIX box that allows me to build)
In the AIX box how I can see that I am using master or inside a particular branch. What changes inside .git that drives which branch I am on?
Git Solutions
Solution 1 - Git
git branch with no arguments displays the current branch marked with an asterisk in front of it:
user@host:~/gittest$ git branch
* master
someotherbranch
In order to not have to type this all the time, I can recommend git prompt:

Git stores the HEAD in the file .git/HEAD. If you're on the master branch, it could look like this:
$ cat .git/HEAD
ref: refs/heads/master
Solution 2 - Git
Try using the command: git status
Solution 3 - Git
You can look at the HEAD pointer (stored in .git/HEAD) to see the sha1 of the currently checked-out commit, or it will be of the format ref: refs/heads/foo for example if you have a local ref foo checked out.
EDIT: If you'd like to do this from a shell, git symbolic-ref HEAD will give you the same information.
Solution 4 - Git
.git/HEAD contains the path of the current ref, the working directory is using as HEAD.

It sounds like you mounted the drive on which the git repository is stored on another server, and you are asking how to modify that. If that is the case, this is a bad idea.
The build server should have its own copy of the git repository, and it will be locally managed by git on the build server.
The build server's repository will be connected to the "main" git repository with a "remote", and you can issue the command git pull to update the local repository on the build server.
If you don't want to go to the trouble of setting up SSH or a gitolite server or something similar, you can use a file path as the "remote" location. So you could continue to mount the Linux server's file system on the build server, but instead of running the build out of that mounted path, clone the repository into another folder and run it from there.
