问题
I want to checkout multiple branches of the same git repostiory on the same Computer (Linux and Windows). However as the repository might be huge, I would prefer to have the repository once and only multiple working directories.
Is this possible? How so?
回答1:
It is possible since Git 2.5 and its git worktree command.
It replaces an older script contrib/workdir/git-new-workdir, with a more robust mechanism where those "linked" working trees are actually recorded in the main repo new $GIT_DIR/worktrees folder (so that work on any OS, including Windows).
Once you have cloned a repo (in a folder like /path/to/myrepo), you can add worktrees for different branches in different independent paths (/path/to/br1, /path/to/br2), while having those working trees linked to the main repo history (no need to use a --git-dir option anymore)
See "Multiple working directories with Git?"
