ssh git@git.bytefreaks.net info | cut -f 2 | tail -n +3 | xargs -I {} -n 1 git clone ssh://git@git.bytefreaks.net/{}
The above command will connect to the git server (git.bytefreaks.net) that is using gitolite and get a list of all the repositories you have access to using ssh git@git.bytefreaks.net info
The command should return a list similar to this:
hello bytefreaks, this is git@git running gitolite3 v3.5.3.1-1-gf8776f5 on git 1.7.1 R W Repo1 R W Repo2 R W Repo3 R Repo4
From the results, we remove the first 3 lines as they contain no useful information to cloning all the repositories. From the rest of the lines, where each line contains the information for a repository we have access to, we keep the third column only as it is the one that holds the repository name as it is stored on the server.
On the last stage of the pipe we have a list of the names of the repositories, using xargs, we assign each repository name to the special variable {} and processing one result at a time we clone the git repository to the current directory under the folder that is named as the repository.
