To commit and perform such operations in Git, a user name and email need to be provided. These are global configuration values in Git.
$ git config --global user.name "Average Joe" $ git config --global user.email "email@example.com"
These settings are written to the global gitconfig file of the user.
If you prefer using the TortoiseGit GUI to perform this operation, see this post.
Tried with: Git 1.8.0
