[LU Chuck] Hi Hannes,
         I used ... literally when I cited the command. I write the command with ... directly as the document introduce the usage like that.
         You can check the document https://git-scm.com/docs/git-filter-branch#_examples about the --env-filter section.

         Hi Philip,
         I also tried to execute the command without ..., 
         git filter-branch --env-filter 'export GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"' 67d9d9..f70bf4
         then I will get another error " You must specify a ref to rewrite."

         Hi team
         I have five commits A,B,C,D,E with commit id as following:
         A(67d9d9)<--B(9c1580)<--C(2eec4d)<--D(a45995)<--E(f70bf4)  
         The commits B,C,D,E 's commiter date and author date are not the same. I want to use filter-branch command to make the commiter date same as the author date.
         I am using the following command to achieve re-write history:
         git filter-branch --env-filter 'export GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"' ... A..E
         However the command did not work.
