问题描述

我最近需要使用'git am'将16个补丁应用到我的回购库中，并且我非常小心地为每个补丁使用'--committer-date-is-author-date'。但是，我还需要调整每个amd补丁的提交消息，并且 - 在完成所有16个补丁之后 - 我发现'commit --amend'碰撞了每个补丁的时间戳。

我终于明白，我的问题可以一举解决， git rebase --committer-date-is-author-date< SHA-commit-before-patches-patches>

但是在尝试用'filter-branch'解决我的问题之前没有解决问题。我很好奇我做错了什么。这是我的尝试：

 >  $ GIT_AUTHOR_DATE 的值包含空格，所以您必须引用它（ -0500 是你的时区偏移量）： 
 
 
  git filter-branch  - env-filter \ 
'export GIT_COMMITTER_DATE =$ GIT_AUTHOR_DATE'SHA1..HEAD 
  
 
I recently needed to apply 16 patches to my repo, using 'git am', and I was careful to use '--committer-date-is-author-date' for each one.  However, I also needed to adjust the commit message for each am'd patch, and-- after I was done with all 16-- I discovered that 'commit --amend' bumped the committer timestamp for each of them.
I eventually learned that my problem could be solved in one fell swoop with
git rebase --committer-date-is-author-date <SHA-of-commit-prior-to-patches>
but not before trying to solve my problem with 'filter-branch', which did not work.  I am curious what I did wrong.  Here is my attempt:
git filter-branch --env-filter \
    'export GIT_COMMITTER_DATE=$GIT_AUTHOR_DATE' SHA1..HEAD
And here is the result:
Rewrite 1c52265d1f06bd67e0fed1c09e1e75249424476e (1/15)/usr/lib/git-core/git-filter-branch: 1: export: -0500: bad variable name
What did I do wrong?  Am I not allowed to set/export one variable to be the value of another, within an env-filter?   Note that I adapted my approach from one that conditionally changed both GIT_AUTHOR_DATE and GIT_COMMITTER_DATE if $GIT_COMMIT matched a particular SHA, but in that case both GIT_*_DATE variables were being set to a constant string, rather than another variable.
 解决方案 
The value of $GIT_AUTHOR_DATE contains spaces, so you have to quote it (-0500 is your time zone offset):
git filter-branch --env-filter \
  'export GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"' SHA1..HEAD
