gitdiff的含义是什么意思

git中diff的含义是什么

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的区别。

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]
