Git: swap the main working tree with a linked working tree?

Question

I'm trying to find out if there's any way to swap working trees. My company has a lot of scripts that assume a specific directory structure, so to be able to work with multiple working trees, I would need the "new" linked worktree to take the place of the main worktree.

I found git worktree move <worktree> <new-path> but that doesn't allow "main" working trees to be moved, so there's no chance of swapping.

Ideally, there would be a git worktree swap <worktree> <path> where:

• if <path> is a worktree, it swaps them
• if <path> is a commit-ish, it adds a new worktree with <worktree>'s name for the commit-ish, then swaps them

Answer 1

There is no automated way to move a main worktree, however, you can do it manually:

• rename the main worktree, eg mv master main
• edit the .git files in every link worktree to reflect that change, eg: sed -i 's!/master/!/main/!' .git

.git is a directory in the main worktree, but just a text file containing the path to the main worktree in the link worktree, which you can edit with your favourite editor.
