update all git repositories in a folder. There are two optional arguments that you can pass while running the script.

Usage ./update-git-repos.sh <folder_path> <folder_name_to_skip>

• copy the content or download the file update-git-repos.sh
• chmod +x update-git-repos.sh
• ./update-git-repos.sh root_folder_path folder_name_to_skip

If no arguments passed it update all git repositories in the current directory without skipping any folder
