This seems to be a copy of Mathias Bynen's Dotfiles (https://github.com/mathiasbynens/dotfiles/blob/master/.osx, 'sensible hacker defaults for OS X'), with a few minor changes. Specifically, comments explainung each line have been changed to echo statements, and the following lines have been inserted:

  echo "Use current directory as default search scope in Finder"
  defaults write com.apple.finder FXDefaultSearchScope -string "SCcf"

  echo "Show Path bar in Finder"
  defaults write com.apple.finder ShowPathbar -bool true

  echo "Show Status bar in Finder"
  defaults write com.apple.finder ShowStatusBar -bool true

  echo "Set a shorter Delay until key repeat"
  defaults write NSGlobalDomain InitialKeyRepeat -int 12

Also, some commands have been commented out:

  # Automatically hide and show the Dock
  # defaults write com.apple.dock autohide -bool true

  # Show remaining battery time; hide percentage
  # defaults write com.apple.menuextra.battery ShowPercent -string "NO"
  # defaults write com.apple.menuextra.battery ShowTime -string "YES"

  # echo "Always show scrollbars"
  # defaults write NSGlobalDomain AppleShowScrollBars -string "Auto"

  # Disable window animations and Get Info animations in Finder
  # defaults write com.apple.finder DisableAllAnimations -bool true

  # Don’t animate opening applications from the Dock
  # defaults write com.apple.dock launchanim -bool false

  # Disable opening and closing window animations
  # defaults write NSGlobalDomain NSAutomaticWindowAnimationsEnabled -bool false

  # Empty Trash securely by default
  # defaults write com.apple.finder EmptyTrashSecurely -bool true

  # defaults write com.apple.Safari ProxiesInBookmarksBar "()"
