 However, you may want to use `git fetch` instead. One reason to do this may be that you expect conflicts. Conflicts can occur in this way if you have new local commits and new commits on the remote. Just like a merge conflict that would happen between two different branches, these two different lines of history could contain changes to the same parts of the same file. If you first operate `git fetch`, the merge won't be initiated, and you won't be prompted to solve the conflict. This gives you the flexibility to resolve the conflict later without the need for network connectivity.
 
-Another reason you may want to run `git fetch` is to update to all remote tracking branches before losing network connectivity. If you run `git fetch`, and then later try to run `git pull` without any network connectivity, the `git fetch` portion of the `git pull` operation will fail.
