I created a new branch named hotfix from master. I switched to the branch, changed 1 file. Now I want to see the diff from the both using git diff hotfix master I do not see any output (difference). When I do a git status I see my file with status mofified, not staged for commit. Also, I can see that I am working with the correct branch, hotfix What am I doing wrong? -fuz ^ permalink raw reply [flat|nested] 5+ messages in thread

Since you just created the branch, and did not add any content, there is no difference to see. A branch is just a pointer to a commit. You now have two pointers pointing at the same commit. If you want to see the difference between your changes and the master branch, you can omit the first reference: git diff master When you start adding commits to your hotfix branch, you will be able to see the diff between that and master with the command that you gave. However, your arguments may be in the reverse order than what you expect. You want to specify master first because that is the mainline branch (I presume). When you have several commits on your hotfix branch, you can refer to older commits to diff against. There are several ways to refer back, but the simplest is to use a tilde '~' followed by a number to count back. For example 'hotfix~1' refers to the parent commit on the hotfix branch. There is a lot in the documentation[1], so take a look there for more info.

The --stat and --numstat options count the lines added and deleted for each file. Is there a way to report the lines modified for each file. For example: Given content below for commit 1: aaaaa ccccc Given content below for commit 2: aaaaa bbbbb ccccc Given content below for commit 3: Aaaaa Bbbbb ccccc ddddd git diff --numstat between commits 1 and 2 will report one line added. git diff --numstat between commits 2 and 3 will report three lines added and two lines deleted. I'd like to see the diff between commits 2 and 3 report two lines modified and one line added. Can this be done? Best, Carter ^ permalink raw reply [flat|nested] 5+ messages in thread

For example: Not really, because it's not well defined. Consider your example: > Given content below for commit 1: > aaaaa > ccccc > > Given content below for commit 2: > aaaaa > bbbbb > ccccc > > Given content below for commit 3: > Aaaaa > Bbbbb > ccccc > ddddd How do we know that "Aaaaa" is a modification of line "aaaaa", and not simply the deletion of the old line and the addition of a new one? It's easy to come up with a case where that is more obvious: -aaaaa +ddddd but there are many shades of gray in between. Is: -aaaaa +Aaada the deletion of an old line and the introduction of a new one, or the modification of an existing line? So fundamentally the diff format just deals with added and removed lines, and modifications are represented as a delete followed by an add. Which isn't to say you couldn't think of many clever algorithms for heuristically determining a modification, but git doesn't do that itself in numstat. -Peff ^ permalink raw reply [flat|nested] 5+ messages in thread
