Basic Tiger Filesystem Navigation
The most basic commands for dealing with the Unix filesystem are those for moving around the filesystem (changing that “somewhere” that the shell always is) and for listing the contents of directories (finding out what's in the same location as the shell or in some other directory). Before you start moving around, however, it's a good idea to be able to find out where you are.
Finding Your Current Location: pwd
The pwd command (print working directory) prints the full path to the current working directory—the location where you are at the moment in this particular shell.
