git - How to clone all repos at once from GitHub?

Question

I have a company GitHub account and I want to back up all of the repositories within, accounting for anything new that might get created for purposes of automation. I was hoping something like this:

git clone git@github.com:company/*.git 

or similar would work, but it doesn't seem to like the wildcard there.

Is there a way in Git to clone and then pull everything assuming one has the appropriate permissions?

On Windows and all UNIX/LINUX systems, using Git Bash or any other Terminal, replace YOURUSERNAME by your username and use:

CNTX={users|orgs}; NAME={username|orgname}; PAGE=1
curl "https://api.github.com/$CNTX/$NAME/repos?page=$PAGE&per_page=100" |
  grep -e 'git_url*' |
  cut -d " -f 4 |
  xargs -L1 git clone

• Set CNTX=users and NAME=yourusername, to download all your repositories.
• Set CNTX=orgs and NAME=yourorgname, to download all repositories of your organization.

The maximum page-size is 100, so you have to call this several times with the right page number to get all your repositories (set PAGE to the desired page number you want to download).

Here is a shell script that does the above: https://gist.github.com/erdincay/4f1d2e092c50e78ae1ffa39d13fa404e
