重写git历史，替换每个文件中的单词 [英] Rewrite git history replacing a word in every single file

问题描述

我想用git-filter-branch重写我的仓库的git历史记录，以便在所有文件中用bar.foo替换所有出现的foo.bar。

我该如何做到这一点？

更新：

我一直在玩 - tree-filter参数，我已经能够用这个替换指定文件中的单词：

  git filter-branch  - f --tree-filter'
 if [-f testfile] 
 then 
 sed -is / foo.bar / bar.foo / g testfile 
 fi' -   - 所有
  

这似乎是我能达到我想要的最接近的水平。

解决方案

就其效果而言，您可以将它想象为您已经完成：

  git checkout< rev> 
  

，以便工作目录现在包含与给定修订相关的树。 （事实上​​，它几乎检查每一个版本，进入一个临时目录，这就是为什么它很慢。另见 -d 标志。）如果你想要一个改变树中的每个文件，你可能会这样做：

  find。 -type f -print | xargs sed -i''-e's / foo \..bar / bar.foo / g'
  

<关于 - tree-filter 的特殊之处在于它自动执行任何必需的 git add 和/或 git rm （因此 -i''; -i .bak 会 git add 所有 .bak 文件）。

< （请记住，如果您有标签，请使用 - tag-name-filter ，并且注意在注释标签上删除签名。）

I want to rewrite the git history of my repository with git-filter-branch to replace all occurrences of "foo.bar" with "bar.foo" in all files.

How can I achieve this?

Update:
I've being playing with the --tree-filter parameter and I've been able to replace the word in a specified file with this:

git filter-branch -f --tree-filter '
    if [ -f testfile ]
    then
        sed -i s/foo.bar/bar.foo/g testfile
    fi ' -- --all

This seems to be the closest I can get to achieve what I wanted.

解决方案

The tree filter is run on every tree being filtered, one tree at a time.

In terms of its effect, you can imagine it as if you had done:

git checkout <rev>

so that the work directory now contains the tree associated with the given revision. (In fact, it does pretty much check out every revision, into a temporary directory, which is why it's so slow. See also the -d flag.) If you want a change made to every file in the tree, you might do:

find . -type f -print | xargs sed -i '' -e 's/foo\.bar/bar.foo/g'

The special thing about --tree-filter is that it automatically does any required git add and/or git rm (hence -i ''; -i .bak would git add all the .bak files).

(Remember to use --tag-name-filter if you have tags, and beware of signature removal on annotated tags.)
