The --author option doesn t work       Please tell me who you are   Run    git config --global user email  you example com    git config --global user name  Your Name    This does   git -c user name  A U Thor  -c user email author example com commit

It is all dependent on how you commit    For example    git commit -am  Some message    will use your    gitconfig username  In other words  if you open that file you should see a line that looks like this    user      email   someemail gmail com   That would be the email you want to change  If your doing a pull request through Bitbucket or Github etc  you would be whoever you re logged in as

The minimal required author format  as hinted to in this SO answer  is  Name  lt email gt    In your case  this means you want to write  git commit --author  Name  lt email gt   -m  whatever    Per Willem D Haeseleer s comment  if you don t have an email address  you can use  lt  gt    git commit --author  Name  lt  gt   -m  whatever    As written on the git commit man page that you linked to  if you supply anything less than that  it s used as a search token to search through previous commits  looking for other commits by that author

Format  A U Thor  lt author example com gt    simply mean that you should specify  FirstName MiddleName LastName  lt email example com gt    Looks like middle and last names are optional  maybe the part before email doesn t have a strict format at all   Try  for example  this   git commit --author  John  lt john doe com gt   -m  some fix    As the docs say     --author  lt author gt         Override the commit author  Specify an explicit author using the standard         A U Thor  lt author example com gt  format  Otherwise  lt author gt  is assumed to         be a pattern and is used to search for an existing commit by that author          i e  rev-list --all -i --author  lt author gt    the commit author is then copied         from the first such commit found    if you don t use this format  git treats provided string as a pattern and tries to find matching name among the authors of other commits

Just supplement      git commit --author  john doe com   -m  Impersonation is evil      In some cases the commit still fails and shows you the following message          Please tell me who you are       Run      git config --global user email  you example com     git config --global user name  Your Name       to set your account s default identity    Omit --global to set the identity only in this repository       fatal  unable to auto-detect email address  got  xxxx    So just run  git config   then  git commit

An alternative if the concern is to hide the real email address   If you are committing to Github you don t need a real email you can use  lt username gt  users noreply github com  Regardless of using Github or not  you probably first want change your committer details  on windows use SET GIT       GIT COMMITTER NAME  username   GIT COMMITTER EMAIL  username users noreply github com    Then set the author  git commit --author  username  lt username users noreply github com gt     https   help github com articles keeping-your-email-address-private

The      standard A U Thor  lt author example com gt  format   Seems to be defined as followed     as far as i know  with absolutely no warranty    A U Thor   required username   The separation of the characters probably indicates that spaces are allowed  it could also be resembling initials  The username has to be followed by 1 space  extra spaces will be truncated    lt author example com gt    optional email address   Must always be between  lt   gt  signs  The email address format isn t validated  you can pretty much enter whatever you want Optional  you can omit this explicitly by using  lt     If you don t use this exact syntax  git will search through the existing commits and use the first commit that contains your provided string   Examples    Only user name  Omit the email address explicitly   git commit --author  John Doe  lt  gt   -m  Impersonation is evil    Only email  Technically this isn t possible  You can however enter the email address as the username and explicitly omit the email address  This doesn t seem like it s very useful  I think it would make even  more sense to extract the user name from the email address and then use that as the username  But if you have to   git commit --author  john doe com  lt  gt   -m  Impersonation is evil       I ran in to this when trying to convert a repository from mercurial to git  I tested the commands on msysgit 1 7 10
