Shallow-clone all your GitHub repositories to a local folder. Keep them in sync on every run.

• Your personal repos are mirrored automatically
• Organization repos are mirrored selectively: you choose which orgs to include on the first run, and the choice is remembered
• Repos you delete on GitHub are moved to an archive folder, not lost
• Authentication is handled entirely via GitHub CLI -- no SSH key or token setup required

Enter the folder where you want your mirror: cd "${HOME}/backup/github-mirror".

Then:

sudo apt update && sudo apt install curl git -y && \
  curl -sL https://raw.githubusercontent.com/TurboLabIt/github-mirror/master/download.sh -o github-mirror.sh && \
  bash github-mirror.sh && rm -f github-mirror.sh

On the first run, the script will:

1. Install the GitHub CLI (gh) if not already present
2. Ask you to authenticate via browser
3. Ask which organizations you want to mirror (Y/N for each)
4. Clone everything

On subsequent runs, just re-run the same command from the same folder. No questions asked -- it updates every repo and archives any that no longer exist on GitHub.

your-mirror-folder/
  download.sh
  organizations.conf
  active-repositories/
    personal/
      your-repo-1/
      your-repo-2/
    YourOrg/
      org-repo-1/
      org-repo-2/
  archived-repositories/
    personal/
      deleted-repo_2025-04-12/

Edit organizations.conf and set the value to yes or no:

MyOrg=yes
AnotherOrg=no

Delete a line entirely to be prompted again on the next run.
