git - How to diff committed changes in difftool?

Question

My diff tool works for my local change such as git difftool -x mytool.exe, how could I use the same diff tool for committed change? I tried git show, git log, but cannot find such option.

Answer 1

我经常使用这个命令来查看最近提交引入的图形差异：

 git difftool HEAD~

（这假设没有进行本地更改。如果是，您将看到此差异中的本地更改加起来）。

您还可以指定任何特定的提交或分支，例如

 git difftool abc123~..abc123
