Coming to OSX from a Linux background it struck me hard that there isn’t a single Finder preference/option to allow me to see files starting with a dot (hidden files) in Finder listings. Knowing that this is probably due to security concerns that not-so-advanced users will mess up their whole system, nevertheless i believe Finder should provide this option. I’m used to the great Xubuntu where i simply press Ctrl+h to enable or disable viewing the hidden files, this might not sound like it but for me this is a real productivity booster.
Although i couldn’t find such a perl in OSX i did however find on google a way to allow me to view those pesky files with Finder.
Fire up a terminal session and type the following command:
defaults write com.apple.Finder AppleShowAllFiles YES
Then simply hold down Option and click on the Finder icon until it the context menu shows up and then select relaunch. Voilá, if everything went ok nest time you open finder it should show all those files for you.
Edit: Apparently this limitation doesn’t exist anymore in Snow Leopard but since i still haven’t managed to install it on my laptop i have no way of being sure.
