Paths to network resources are denoted in Windows with the \\servername\share\path\to\folder syntax. How does one use such a folder within Git Bash, which uses Unix-style paths?
Actually just cd //servername/share/path/to/folder where //servername/ is followed by at least one shared folder.
You need to associate a drive letter to the network path you want to use. To do this, execute the following command in the Windows cmd shell:
pushd \\servername\share\path\to\folder
The next prompt will carry the assigned drive letter, e.g. Z:\path\to\folder. Now, open Git Bash (it will not work with an already running instance) and go to the new created drive letter:
cd Z:/path/to/folder
or equally
cd /z/path/to/folder
Actually
git clone //servername/path/to/repo.git
works fine for me (using git version 1.9.0.msysgit.0)
If you need it for cloning, more appropriate answer is here:
git clone file:////<host>/<share>/<path>
Notice the word file and 4 slashes after it, that is the trick.
No need to type the path manually. Just right click! on your repository and click Git Bash option. It will open the git bash with your repository path.
Also i suggest to use Mp Network Drive option of windows to map the network location as a drive and use it only.
