`gh pr checkout` Switch to the branch of a pull request

Fetches the code from a pull request and checks it out as a local branch, so you can run or review it. It works for branches in forks as well.

Synopsis

gh pr checkout {NUMBER | URL | BRANCH} [FLAGS]

Option or form	What it does
`-b, --branch NAME`	Local branch name to use
`-f, --force`	Reset the local branch to match the pull request
`--detach`	Check out without creating a branch
`--recurse-submodules`	Also update submodules

Check out pull request 42

gh pr checkout 42

Switched to branch 'feature/search'

Check out from a URL

gh pr checkout https://github.com/octocat/Hello-World/pull/42

Use your own branch name

gh pr checkout 42 --branch review-42

Look without making a branch

gh pr checkout 42 --detach

Run it in a clone of the repository. gh sets up tracking so git pull brings new commits from the author.
If you have local changes, commit or stash them first.
Without the GitHub CLI you can use git fetch origin pull/42/head:pr-42.
