Git Cheat Sheet · Worktrees
Find a branch's worktree
git worktree list
A branch can only be checked out in one worktree at a time: otherwise, a commit in one would move the branch under the other's files. git worktree list shows where it is.
What it does
A branch can only be checked out in one worktree at a time: otherwise, a commit in one would move the branch under the other's files. Elsewhere, it can therefore be neither checked out, nor advanced, nor deleted.
A use case
The checkout of main is refused because main is already checked out in your main folder: just go work there.
On the command line
git worktree list- Shows the branch checked out in each folder.
git worktree list --porcelain- The same list, in a format easy for a script to read.
git -C <folder> switch <other-branch>- Frees the branch by switching branches in the other worktree.
In Merathon
- Right-click the branch: "Checkout" is grayed out with the note "Checked out in another worktree".
- Choose "Open its worktree" to go there.
Frequently asked questions
Why can my branch not be deleted?
It is checked out in a worktree. Delete that worktree or switch branches in it, then run the deletion again.
The worktree no longer exists, but the branch stays blocked. What should I do?
The repository keeps its reference: git worktree prune removes it and frees the branch.
