如何根据文件扩展名过滤git diff？

Question

是否可以选择将git diff限制为一组给定的文件扩展名？

Answer 1

是的，如果你确保 git 扩展一个 glob 而不是你的 shell，那么它会在任何级别匹配，所以这样的东西（引号很重要）应该可以正常工作。

git diff -- '*.c' '*.h'

Answer 2

要递归包含文件（包括当前目录），这对我有用：

git diff -- '***.py'

Answer 3

Either use your shell's globstar (which does a recursive search) ^{1 ,2 :}

shopt -s globstar 
git diff -- *.py **/*.py

or use find:

find -name '*.py' -print0 | xargs -0 git diff --

Both of these are special-names and whitespace proof. Although you might want to filter for directories having the .py extension :)

---

1 I like to do git diff -- {.,**}/*.py usually

2 When globstar is enabled, git diff -- **/*.py already includes ./*.py . In Bash's manpage: 'If followed by a /, two adjacent *s will match only directories and subdirectories.'

Answer 4

For simple file patterns, this seems to work:

$ git ls-files -zm '*.txt' | xargs --null git diff

Whitespace safe, and you can have multiple extensions too:

$ git ls-files -zm '*.h|*.c|*.cpp' | xargs --null git diff

Answer 5

As tested on git version 2.18.0, the file extension should be quoted with double quotes. If you want to find the last differences between your local repository and the remote one, after pulling, you can use:

git diff YourBranchName@{1} YourBranchName --name-only "*.YourFileExtionsion"

For example:

git diff master@{1} origin/master --name-only "*.cs"

Answer 6

Command line argument for extension.

git diff *.py

In the alternative, you can pipe find into git diff :

find . -name '*.py' -type f | git diff --

Answer 7

None of the answers above seem to work for me under git bash on Windows. I am not sure if it is a version thing (I'm using 1.8.4) or Windows/bash thing; also, in my case, I wanted to diff two branches where each branch had additional files not present in the other branch (thus the 'find' based ones are remiss).

Anyway this worked for me (in my example, looking for a diff between python files):

git diff branch1 branch2 -- `git diff --summary branch1 branch2 | egrep '\.py$' | cut -d ' ' -f 5`

Answer 8

git diff will only show differences in unstaged files.

I found this question because I wanted to exclude .info files from git diff . I achieved this by staging it with git add *.info , which reduces the files left.

Answer 9

I wound up with this:

commit=<the_commit_hash_goes_here> && git diff --name-only $commit | grep -i Test | egrep -v '\.sql$' | xargs git diff $commit --

This shows diffs for the specified commit only if the filename contains the word 'test' (case insensitive) and does not end with .sql , modify the pipeline as necessary for your case.

Attention that params order makes difference...for example:

git diff master --name-only --relative -- "**/*.ts" "**/*.tsx" "**/*.js" "**/*.jsx" "**/*.vue"

'diff' need to be followed with 'master'
