Using Pushd & Popd

I created this video as a quick tutorial on how to use two very cool commands in Linux.  Normally, if you want to switch between two directories, you can just use the cd (change directory) command.  That works fine but, after I discovered pushd and popd, I never went back.  In my opinion, pushd and popd are way more efficient than cd and they are not used enough.  Enjoy.
