Keep multiple Git repositories up to date?

Question

I and my coworkers are working on multiple repositories. They are all independent, and do not share the same path. For instance

• C:\Website A
• C:\Website B
• C:\Website C
• D:\GitClientTools
• C:\Users\me\ServerFiles

Someone may clone repositories to different folders.

Is there a way or tool that automatically periodically pull repositories?

I understand if working directoy has changes, pull may fail. In that case, giving a notification is fine.

I looked at SourceTree and Git Extensions. They can auto fetch, but still require a manual pull or merge.

I don't want to every time go to each of the repository and run the pull.
