If you need to modify the author info in your repository's history, you can do the following:

git filter-branch --commit-filter '
        if [ "$GIT_COMMITTER_NAME" = "<Old Name>" ];
        then
                GIT_COMMITTER_NAME="<New Name>";
                GIT_AUTHOR_NAME="<New Name>";
                GIT_COMMITTER_EMAIL="<New Email>";
                GIT_AUTHOR_EMAIL="<New Email>";
                git commit-tree "$@";
        else
                git commit-tree "$@";
        fi' HEAD

git filter-branch --index-filter 'git rm --cached --ignore-unmatch <file>' HEAD

== Overwriting (reset) a local branch with remote branch ==
