Need for a bare repo in GIT

问题

While reading the tutorials I keep hearing that I need to create something known as a bare repository for sharing all the files in the repo.

I also hear that a bare repo does not contain any of the worfiles.

If it does not have any workfiles then what will the other users clone on their local machines???

I currently have a directory in my linux server which i need to share among several users which will be accessing through eclipse ide's.

Can anyone explain the issues highlighted above in plain words.

When you git push to a remote repository, you can overwrite the files in the working directory. To avoid this, you can use a bare repository, which doesn't even have a working directory.

However, because there's no working directory, you can't work in the bare repo, you can only push to it and pull from it. This makes it ideal as a "collection point" or "collaboration repo" for multiple users -- which is why the git tutorials say to use a bare repository for servers.

A normal git repo looks like this:

my-repository/
    .git/
        COMMIT_EDITMSG 
        ORIG_HEAD
        description    
        index
        objects
        FETCH_HEAD     
        branches       
        gitk.cache     
        info           
        refs
        HEAD           
        config         
        hooks          
        logs
    file1
    file2

my-repository is the working directory, containing the files you work on file1, file2 etc. All the git data is stored in the .git folder.

On a bare repository, you don't have a working folder. All you have is the contents of the .git folder, stored in the top-level of that repository:

my-bare-repository/
    COMMIT_EDITMSG 
    ORIG_HEAD
    description    
    index
    objects
    FETCH_HEAD     
    branches       
    gitk.cache     
    info           
    refs
    HEAD           
    config         
    hooks          
    logs

This is what other users clone.

Yes it is.

A remote repository is generally a bare repository — a Git repository that has no working directory. All data is stored in .git directory and working directory is not needed. It is just a collaboration point.

If it does not have any workfiles then what will the other users clone on their local machines???

Data from .git directory will be cloned.
