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
