pwd command options for displaying the current directory's full path

A quick note because I always forget the -P option.

The pwd command stands for "Print working directory."
Since I customize my shell display, I find myself using it quite often...

Command	Effect
pwd	Displays the full path of the current directory
pwd -L	logical. *Follows symbolic links.
pwd -P	physical. *Does not follow symbolic links.
