download-all-repos.sh

#!/bin/bash

# Clone all github.com repositories for a specified user.

if [ $# -eq 0 ]
  then
    echo "Usage: $0 <user_name> "
    exit;
fi

USER=$1

# clone all repositories for user specifed
for repo in `curl -s https://api.github.com/users/$USER/repos?per_page=1000 |grep git_url |awk '{print $2}'| sed 's/"\(.*\)",/\1/'`;do
git clone $repo;
done;

its needs to replace git_url to clone_url

#!/bin/bash

# This BASH script clones all github.com repositories for a specified user!
# HOW TO USE THE SCRIPT: 
# CD to the directory where you want to download all the repositories (or open terminal there)
# then execute the script by defining the path to where you saved the .sh file, followed by your Github username:
# "sh the/path/to/download-all-repos.sh <github_user_name_here>"
# Then hit RETURN and watch the magic happen

if [ $# -eq 0 ]
  then
    echo "ERROR: Github username is missing, you shoud type THIS in your terminal: "
    echo "$0 <github_user_name_here> "
    exit;
fi

USER=$1

# clone all repositories for specified user:

Thanks a lot ! I have added a new functionality.

The added functionality allows for two different actions, depending on the state of the repository.

1. Cloning non-existent repositories
2. Pulling existing repositories

The code with the changes is here:
