Some Rake Tasks to Automate Common Git Tasks -- I use this at johnlockwood.com.

git_tasks.rake

# Use rake --tasks | grep git for a list
# The most useful is rake git:checkin, which is essentially add + commit + message + push.

namespace :git do

  desc "Run ssh-add to enter password for your ssh key a single time"
  task :setup do
    sh "ssh-add"
  end

  desc "Stage any deleted files to prepare for commit"
  task :delete do
    sh "git ls-files --deleted -z | xargs -0 git rm"
  end

  desc "Add files, commit them, push them"
  task :checkin do
    do_checkin
  end

  desc "Add / commit / push the wiki"
  task :checkin_wiki do
    chdir "wiki"
    do_checkin
    chdir ".."
  end

  desc "Tests showing argument"
  task :show_arg, [:param1] do |t, args|
    puts "Param1 is: #{args.param1}"
  end

  desc "Git Status"
  task :status do
    sh "git status"
    chdir "wiki"
    sh "git status"
  end

  def do_checkin
    print "Enter commit message to add, commit and push files, or blank to quit:\n"
    commit_message = STDIN.gets.chomp
    if commit_message.nil?
      print "Commit and push aborted at user request."
      return
    end
    sh "git add ."
    sh "git commit -m\"#{commit_message}\""
    sh "git push"
  end
end
