How to show hidden files in Finder?

By default, the Finder does not show any files or folders that begin with a dot.

To allow Finder to show hidden files, run the following command in the console:

defaults write com.apple.finder AppleShowAllFiles TRUE ; killall Finder

To hide the display of hidden files again, use the command:

defaults write com.apple.finder AppleShowAllFiles FALSE ; killall Finder

If you find it difficult to work with the Terminal/Console, then in the Finder use this combination:

Command Shift .

In this way, you can both disable and enable the ability to view hidden files, such as .htaccess, .ftpaccess, .git, etc.
