A funny story about "cd -". When I first started learning the command line during a programming course, they basically told us just enough to get by in order to complete the assignments. Somehow, "cd -" was mentioned but not "cd ..", so for a long time I used "cd -" as my only method for getting to the parent directory! (since that was usually where I had just come from). Reading about everyone discovering "cd -" much later in learning bash is very amusing, since I have been using it since day one (albeit in a totally incorrect way!)
