I have a project, that is stored as a git-repo. The repo has several branches. Also I use OpenGrok (source browser) for the project. To be able to show all branches I cloned the project several times, after that did 'checkout' the required branch.
To update each workdir I do 'git fetch && git merge' for each workdir.
The Q: Is there a way to have one "main" clone, where need to do git fetch. After that each workdir will be updated from the "main" clone.
Exactly that Problem ist addressed by the git worktree commands: one repo but several working trees. Lookup the manual for that command!
