Unhide folders in OS X

I frequently find myself having to copy or dig into the Library folder on my Mac. Apple has decided to make the folder hidden, so I usually press CMD-SHIFT-G on the keyboard and type out my path. But here is another option:

Open Terminal, and type:

$ chflags nohidden ~/Library

This will work for any folder that is hidden, and if you change your mind, just change nohidden to hidden to hide it again.
