Automate git pulling

Automate git pulling

#!/usr/local/bin/ruby -swI .
#
# AUTOMATE UPDATING ALL PROJECTS
#
# Problem: going to each project and then pulling changes.
# Solution: Automate git pulling for all my projects
#
# 1. Create a pull_projects file and add the code from this gist
# 2. Move the file into a directory that is in your path, i.e. $PATH
# 3. Make the file executable, eg. chmod +x /usr/local/bin/pull_projects
# 4. Run e.g. pull_projects dir1_with_projects dir2_with_projects
# 5. Optional: run this on terminal startup so you dont even have to do it manually

if ARGV.length == 0
        raise "You must specify atleast one project directory to pull changes from remote repository"
end

ARGV.each do |projects_dir|
        puts "Starting to pull projects in #{projects_dir}\n"
        dirs = Dir.entries projects_dir
        dirs.reject!{|entry| entry.match(/^\./)}
        dirs.each do |entry|
                full_dir_path = "#{projects_dir}/#{entry}"
                if File.directory? full_dir_path 
                        Dir.chdir(full_dir_path)
                        check_diff = `git diff`
                        # Don't pull if I have local changes
                        unless check_diff.match(/^$/)
                                puts "You have pending changes in #{entry}"
                        else
                                puts "PULLING #{entry}....\n"
                                system "git pull"
                        end 
                        Dir.chdir('../')
                end 
        end
