I find myself doing this a lot when cherry-picking a commit from another branch.
$ git log -1 another_branch
commit <commit_sha>
// copy <commit_sha>
$ git cherry-pick <commit_sha>
Can I do all of this in one command, if so, what is it?
Just go with:
$ git cherry-pick another_branch
This will cherry-pick the last commit from another_branch.
Branches in git are just references to the last commit in that branch, you can use them instead of commit SHAs in your commands.
