自动化程度更高：

#!/usr/bin/env bash

filter_commit_to_files() {
    FILES="$1"
    SHA="$2"
    git show "$SHA" -- $FILES | git apply --index -
    git commit -c "$SHA"
}

示例用法：

filter_commit_to_files "file1.txt file2.txt" 07271c5e

我通过复制并粘贴到外壳中来定义它。您不需要here文档。

与Jefromi的答案相比，这种方法的优势可能在于您不必记住git重置的哪个行为是正确的：）

 # Create a branch to throw away, on which we'll do the cherry-pick:
 git checkout -b to-discard

 # Do the cherry-pick:
 git cherry-pick stuff

 # Switch back to the branch you were previously on:
 git checkout -

 # Update the working tree and the index with the versions of A and B
 # from the to-discard branch:
 git checkout to-discard -- A B

 # Commit those changes:
 git commit -m "Cherry-picked changes to A and B from [stuff]"

 # Delete the temporary branch:
 git branch -D to-discard

有时，使用签出从提交中获取特定文件可能更容易。在我看来，它给了你更多的控制权，而且在樱桃采摘后不必检查和拆封。

我会这样做：

git checkout <branch|hash> -- path/to/file1 path/to/filen

然后，在提交之前，取消编写必要的更改以适应代码并对其进行测试。如果一切按预期进行，那么提交。

我会使用cherry-pick-n（--no-commit）来完成，它允许您在提交之前检查（和修改）结果：

git cherry-pick -n <commit>

# unstage modifications you don't want to keep, and remove the
# modifications from the work tree as well.
# this does work recursively!
git checkout HEAD <path>

# commit; the message will have been stored for you by cherry-pick
git commit

如果绝大多数修改都是您不想要的，那么您可以重新设置所有内容，然后添加您想要的内容，而不是检查各个路径（中间步骤）：

# unstage everything
git reset HEAD

# stage the modifications you do want
git add <path>

# make the work tree match the index
# (do this from the top level of the repo)
git checkout .

Cherry pick是从特定的“提交”中选择更改。最简单的解决方案是选择某些文件的所有更改

 git checkout source_branch <paths>...

例如：

$ git branch
* master
  twitter_integration
$ git checkout twitter_integration app/models/avatar.rb db/migrate/20090223104419_create_avatars.rb test/unit/models/avatar_test.rb test/functional/models/avatar_test.rb
$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   new file:   app/models/avatar.rb
#   new file:   db/migrate/20090223104419_create_avatars.rb
#   new file:   test/functional/models/avatar_test.rb
#   new file:   test/unit/models/avatar_test.rb
#
$ git commit -m "'Merge' avatar code from 'twitter_integration' branch"

更新：

使用此方法，git不会合并文件，它只会覆盖在目标分支上所做的任何其他更改。您需要手动合并更改：

$git diff HEAD文件名

将分支合并为新分支（挤压）并删除不需要的文件：

git checkout master
git checkout -b <branch>
git merge --squash <source-branch-with-many-commits>
git reset HEAD <not-needed-file-1>
git checkout -- <not-needed-file-1>
git reset HEAD <not-needed-file-2>
git checkout -- <not-needed-file-2>
git commit
