I’m often asked how to merge only specific commits from another branch into the current one. The reason you’d want to do this is to merge specific changes you need now, leaving other code changes you’re not interested in right now behind.
First of all, use git log
or the awesome GitX tool to see exactly which commit you want to pick. An example:
dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
\
76cada - 62ecb3 - b886a0 [feature]
Let’s say you’ve written some code in commit 62ecb3
of the feature
branch that is very important right now. It may contain a bug fix or code that other people need to have access to now. Whatever the reason, you want to have commit 62ecb3
in the master branch right now, but not the other code you’ve written in the feature
branch.
Here comes git cherry-pick
. In this case, 62ecb3
is the cherry and you want to pick it!
git checkout master
git cherry-pick 62ecb3
That’s all. 62ecb3
is now applied to the master branch and commited (as a new commit) in master
. cherry-pick
behaves just like merge
. If git can’t apply the changes (e.g. you get merge conflicts), git leaves you to resolve the conflicts manually and make the commit yourself.
Cherry picking a range of commits#
In some cases picking one single commit is not enough. You need, let’s say three consecutive commits. cherry-pick
is not the right tool for this. rebase
is. From the previous example, you’d want commit 76cada
and 62ecb3
in master
.
The flow is to first create a new branch from feature
at the last commit you want, in this case 62ecb3
.
git checkout -b newbranch 62ecb3
Next up, you rebase the newbranch
commit --onto master
. The 76cada^
indicates that you want to start from that specific commit.
git rebase --onto master 76cada^
The result is that commits 76cada
through 62ecb3
are applied to master
.
