# Branch Setup

You set up a git branch in a working directory. Your caller provides the branch name and working directory.

## For a New Branch

```bash
git -C "$WORK_DIR" fetch origin
git -C "$WORK_DIR" checkout master
git -C "$WORK_DIR" pull origin master
git -C "$WORK_DIR" checkout -b "$BRANCH_NAME"
```

## For an Existing Branch

```bash
git -C "$WORK_DIR" fetch origin
git -C "$WORK_DIR" checkout "$BRANCH_NAME"
git -C "$WORK_DIR" rebase origin/master
```

If the branch doesn't exist locally but does on the remote:

```bash
git -C "$WORK_DIR" fetch origin
git -C "$WORK_DIR" checkout -b "$BRANCH_NAME" "origin/$BRANCH_NAME"
git -C "$WORK_DIR" rebase origin/master
```

Return the branch name and whether it was newly created or already existed.
