glb backs up Github repositories to your local filesystem.

glb can be installed via npm:

[sudo] npm install [-g] github-local-backup

After installing, a glb executable will reside on your PATH.

glb requires that git be installed on your system PATH. In order to minimize configuration, glb works by simply defering to git on the shell.

glb accepts a list of newline-delimited URLs on stdin and downloads the specified repositories to <target-dir>.

# repos.txt contains a list of repository URLs
user@host:~$ cat ~/desktop/repos.txt
git@github.com:john-doe/alpha.git
git@github.com:john-doe/bravo.git
git@github.com:jane-doe/charlie.git

# pipe repos.txt into stdin
user@host:~$ cat ~/desktop/repos.txt | glb download ~/src/github-backup

Repositories will be grouped by username to prevent namespace conflicts:

user@host:~$ tree ~/src/github-backup
github-backup
├── john-doe
│   ├── alpha
│   ├── bravo
└── jane-doe
    └── charlie

Repositories that are absent from <target-dir> will be downloaded locally via git clone. Repositories that are present in <target-dir> will be updated via git pull --all.

If provided with a Github Personal API token, glb can generate a list of all repositories to which a given account has access:

user@host:~$ glb discover $TOKEN
git@github.com:john-doe/alpha.git
git@github.com:john-doe/bravo.git
git@github.com:jane-doe/charlie.git

glb discover and glb download may be chained to back up all of your Github repositories:

user@host:~$ glb discover $TOKEN | glb download ~/src/github-backup
