    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:

    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?

[LU Chuck] Let's move back here, I know what three dots does now. According this documentation https://git-scm.com/docs/gitrevisions#Documentation/gitrevisions.txt-Theem82308203emthree-dotSymmetricDifferenceNotation .
         Then the command I need to run is git filter-branch --env-filter 'export GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"' 67d9d9..f70bf4 
         But why I got the error message " You must specify a ref to rewrite. ".

         When I use command " git log 67d9d9..f70bf4 ", it will list 4 commits. It means the commits range works.
         So, the problem would be, why the git filter-branch could not recognized 67d9d9..f70bf4 as a range of commits?

quoted

    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.
