Assume there's a source branch that we want to pick up some code from: branchA and the target branch is branchB
- Setup meld as difftool:
git config --global diff.tool meld
- Check out working branch:
git co branchB
- Bring up the diff tool:
git difftool -d branchA..branchB
Note:
- co is alias for checkout
- Environment: Linux (Ubuntu)
