     I want to re-write history by filter-branch command over a range of

commits, but the command did not work.

     I have referred to the following three documentation about how to use

git filter-branch:

     You can reproduce the problem by the following steps
     1. clone the repository

     2. checkout to the temp branch
     3. run the command git filter-branch --env-filter 'export
GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"' ... 67d9d9..f70bf4

Did you not tell us everything because you write ... in this message
when you cited the command you used, or do you say that you used ...
literally in the command?

The three dots is provided in the literal EXAMPLES section of the man page. That is
probably an error, as I think it is meant to be an ellipsis to indicate 'insert other
options here'.

Simply remove the three dots ('symmetric diff notation') .

Not sure what the correct change to the man page should be, but clearly it has
caused confusion. It also takes a moment to properly realise which commits the
two dot notation will refer to in the example which may further compound the
confusion about the three dots.

[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.

     4. You will got the info "Found nothing to rewrite"

     However, it was supposed to overwrite the history from commit 9c1580

to commit f70bf4, make the commit date same as date.

     I am not sure if I am using the filter-branch correctly, or if there is a bug in

git?

     Anyone can help me? Thanks in advance.
