How can I show hidden files/folders in Finder

"Open a Terminal and enter:

defaults write com.apple.finder AppleShowAllFiles TRUE

Then, relaunch Finder by typing:

killall Finder

To reverse that, just enter:

defaults write com.apple.finder AppleShowAllFiles FALSE"

"You can use this script toggle between states:

# check if hidden files are visible and store result in a variable
isVisible=”$(defaults read com.apple.finder AppleShowAllFiles)”

# toggle visibility based on variables value
if [ ""$isVisible"" = FALSE ]
then
defaults write com.apple.finder AppleShowAllFiles TRUE
else
defaults write com.apple.finder AppleShowAllFiles FALSE
fi

# force changes by restarting Finder
killall Finder

You can also download an Automator application which will toggle hidden file visibility here:
