git cherry-pick to another branch

Question

I wonder if there is the way to copy one commit to another branch without checking out that branch.

For example, I have two branches: master and p

Here's a small script that creates a temporary clone of the repository, as suggested by user2394284:

_{/usr/bin/git-tmp-clone or ~/bin/git-tmp-clone}

#!/bin/bash

gitTopLevel=$(git rev-parse --show-toplevel)

# Unique name for the temporary clone.
totalhash=$(tar -c "$gitTopLevel/.git" 2> /dev/null | sha256sum | head -c8)

tmprepo="/tmp/$(basename $(pwd))_${totalhash}"

git clone "$gitTopLevel" ${tmprepo}

# Start an interactive shell in the clone. Pass any
# arguments as initial commands to be executed.
/bin/bash --init-file <(echo "cd ${tmprepo}; $@")

# Clean up the clone.
rm -rf ${tmprepo} && echo "Deleted ${tmprepo}"

(This script is less than robust, but it seems to work for me on Ubuntu.)

You can use this to cherry-pick e.g. the last commit on the current brach to another branch, by running

git-tmp-clone "git checkout TARGET_BRANCH
            && git cherry-pick $(git rev-parse --short @)
            && git push origin HEAD"

(Note that in this example, the rev-parse is evaluated in the origin repository before the clone is created! That's why it points to the most recent commit. Adapt as needed.)
