View difference between two Git branches

Comparing changes between different revisions is a pretty frequent task when working with Git. As branches are nothing more than pointers to specific commits, you can easily compare the changes between two branches using the git diff command.

Using git diff <branch>..<other-branch> will display the difference between the two branches. This can be useful to see what changes have been made in one branch compared to another. You can then easily export or apply these changes as needed.

# Syntax: git diff <branch>..<other-branch>

git diff patch-1..patch-2
# Displays the difference between branches `patch-1` and `patch-2`

git diff master..feature > changes.patch
# Exports the changes between `master` and `feature` to a patch file
