ssh git@git.bytefreaks.net info | cut -f 2 | tail -n +3 | xargs -I {} -n 1 -I_repository -- sh -c 'cd _repository; git pull; cd ..;'
The above command will connect to the git server (git.bytefreaks.net) 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.
Afterwards it will remove all columns except the second to filter the column with the repository names and will remove the first 3 lines to keep only the data we are interested in.
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 _repository variable and using one result at a time, we navigate into the folder of the repository using cd and call the pull command.
Note: We assume that all repositories are in the current folder as children and each one is in a sub-folder of its own which is named as the repository is.
