There is one! https://github.com/jupyterhub/nbgitpuller/blob/8827509f728a138b174c61165ebdcc1b0430a136/nbgitpuller/pull.py#L347 although it looks like it isn't documented well?

So it might be more a matter of installing a command line access to the python modules offering such services see : https://stackoverflow.com/a/75419857/1497139

Oh i see what the problem is - the project does not use pyproject.toml yet but still has a setup.py - i didn't expect that and didn't even look for it - so the command is gitpuller.

After install things with

pip install . --user

gitpuller -h
usage: gitpuller [-h] git_url [branch_name] [repo_dir]

Synchronizes a github repository with a local repository.

positional arguments:
  git_url      Url of the repo to sync
  branch_name  Branch of repo to sync
  repo_dir     Path to clone repo under

options:
  -h, --help   show this help message and exit

is available

Unfortunately there is no debug, no verbose and no version option. Having a link to the source code is helpful though.

I still can't find out why nbgitpuller isn't working properly in our environment. Is there a log file somewhere by default?
