git worktree add [from specific commit hash]

so I have a commit hash from earlier in a project. How can I create a new worktree and have it's branch start from this specific commit?

Solution

  • Use the command described in the git worktree documentation:

    git worktree add [--detach] [-b <new-branch>] <path> [<commit-ish>]

    which in this case might be, e.g.:

    $ cd gitrepo
$ git worktree add -b workbranch ../gitrepo.workbranch d16c37964
Preparing ../gitrepo.workbranch (identifier gitrepo.workbranch)
HEAD is now at d16c37964 Merge branch 'jk/attributes-path-doc'

    after which:

    $ cd ../gitrepo.workbranch
$ git status
On branch workbranch
nothing to commit, working tree clean
$ git rev-parse HEAD
