With the release of OS X Mavericks the old Terminal command that causes Finder to show hidden files and directories no longer works. If you want to see hidden files, such as a .gitignore file in your repository, open a Terminal window and run this command:
defaults write com.apple.finder AppleShowAllFiles -boolean true
Then refresh all Finder windows so that they honor the new configuration setting:
To revert back to hiding these files and directories, run the first command but change true to false.
Check out my next blog post to see how this task can be automated by writing a custom Terminal command!
