git diff 命令
Git 基本操作git diff 命令比较文件的不同，即比较文件在暂存区和工作区的差异。
git diff 命令显示已写入暂存区和已经被修改但尚未写入暂存区文件对区别。
git diff 有两个主要的应用场景。
- 尚未缓存的改动：git diff
- 查看已缓存的改动：git diff --cached
- 查看已缓存的与未缓存的所有改动：git diff HEAD
- 显示摘要而非整个 diff：git diff --stat
显示暂存区和工作区的差异:
$ git diff [file]
显示暂存区和上一次提交(commit)的差异:
$ git diff --cached [file] 或 $ git diff --staged [file]
显示两次提交之间的差异:
$ git diff [first-branch]...[second-branch]
在 hello.php 文件中输入以下内容：
<?php echo '千木教程：www.qianmu.net'; ?>
使用 git status 查看状态：
$ git status -s A README AM hello.php $ git diff diff --git a/hello.php b/hello.php index e69de29..69b5711 100644 --- a/hello.php +++ b/hello.php @@ -0,0 +1,3 @@ +<?php +echo '千木教程：www.qianmu.net'; +?>
git status 显示你上次提交更新后的更改或者写入缓存的改动， 而 git diff 一行一行地显示这些改动具体是啥。
接下来我们来查看下git diff --cached的执行效果：
$ git add hello.php $ git status -s A README A hello.php $ git diff --cached diff --git a/README b/README new file mode 100644 index 0000000..8f87495 --- /dev/null +++ b/README @@ -0,0 +1 @@ +# qianmu Git 测试 diff --git a/hello.php b/hello.php new file mode 100644 index 0000000..69b5711 --- /dev/null +++ b/hello.php @@ -0,0 +1,3 @@ +<?php +echo '千木教程：www.qianmu.net'; +?>
