In the other words, is there a better way to do this: git-diff b163512d4eb36ee946908b682c7863658c5a8db4^ b163512d4eb36ee946908b682c7863658c5a8db4 Thanks. Robertoo ``` ## Petr Baudis, 2005-09-22 10:04 Subject: Re: command to show diff of a commit Message-ID: <20050922100458.GF21019@pasky.or.cz> URL: https://gitlist.dev/e/20050922100458.GF21019%40pasky.or.cz In-Reply-To: <72499e3b05092202583f9a751d@mail.gmail.com> ``` Dear diary, on Thu, Sep 22, 2005 at 11:58:32AM CEST, I got a letter where Robert Watson told me that... > Hi, Hi, > I am wondering what is the best way to show the change introduced by a > commit.

Do git-diff-tree -p --pretty b163512d4eb36ee946908b682c7863658c5a8db4 and you're done. If you _just_ want the diff (and not the message), skip the "--pretty".

I know there must be a way to do this. Here is a patch to make the document a bit clearer.
