git - git diff filtered by file name

Question

I would like the results of git diff to be filtered by the file name.

In particular, I want a diff for all of the files named "AssemblyInfo.cs", but located anywhere within the git repository.

I am using git on Cygwin, if that makes a difference.

Answer 1

The simplest method is to simply use a wildcard:

git diff -- '*AssemblyInfo.cs'

At least this works on my Git v1.8.4, bash 3.2, and zsh 5.7.

Answer 2

git diffで区切る必要のあるファイル引数---これを試してください：

find . -name <pattern> | xargs git diff --

xargsは、スペース、タブ、改行などが正しく処理されるようにします。

--name-statusの引数を使用してデバッグできますgit diff。また、試すことができます：

git diff --name-only | grep <pattern>

[編集]試してみてください：

git diff --name-status -- `find . -name '<pattern>'`
ebg@taiyo(98)$ git diff --name-status -- `find . -name '*.scm'`
M       scheme/base/boolean.scm
M       surf/compiler/common.scm
M       surf/compiler/compile.scm
M       surf/compiler/expand.scm

Answer 3

Probably the simplest option is to use:

git diff "*/*AssemlyInfo.cs"

works as of git 2.20.1

Answer 4

You can use pipeline

find . -name AssemblyInfo.cs | git diff

Use find to filter all the files named "AssemblyInfo.cs", then use the output as the parameter of git diff.

Answer 5

While the answer given by GoZoner works for some (hundred?) files, it executes git diff multiple times (in the case of xargs) or fails (in the case of git diff … -- `find …`) if there is a large number of files to diff. This might be a problem or not, depending on your use case.

A possible solution is to create a commit containing only changes to files of interest and diff the commits. Based on an answer on unstaging files matching some pattern I came up with this solution:

git co <new_branch> --detach
git reset --soft <old_branch>

Now git status --porcelain | grep <pattern> shows all files that should be compared. All other files can be listed by passing -v to grep, i.e. git status --porcelain | grep -v <pattern>. This files need to be reset to the state of <old_branch>:

# Remove the destination of renamed and copied files not matching <pattern>
git status --porcelain | grep -v <pattern> | grep '^R \|^C ' | sed 's/.* -> //' | xargs git rm -f --
# Remove added files not matching <pattern>
git status --porcelain | grep -v <pattern> | grep '^A ' | cut -c 4- | xargs git rm -f --
# Restore deleted files not matching <pattern>
git status --porcelain | grep -v <pattern> | grep '^M \|^D ' | cut -c 4- | xargs git checkout HEAD --

(Note that using xargs is not a problem in this case, as calling git rm and git checkout multiple times is ok.)

Now the index (and working copy) only contains changes to the files matched by <pattern>. The next thing to do is to commit this changes:

git commit -m "Changes between <old_branch> and <new_branch> in files matching <pattern>"

That's it! Now we can use git diff as usual:

git diff HEAD^..HEAD

You can use all options or arguments you like.

Note: This solution is not tested extensively and may fail e.g. on files with special characters or other special cases… Suggestions to improve the solution are welcome ;-)

Answer 6

find . -iregex AssemblyInfo\.cs -exec git diff {} +

you can replace the AssemblyInfo\.cs with your regex.
