— Command: cd dir
— Command: chdir dir

Change the current working directory to dir. If dir is omitted, the current directory is changed to the users home directory. For example,

          cd ~/octave
     

Changes the current working directory to ~/octave. If the directory does not exist, an error message is printed and the working directory is not changed.

— Command: ls options

List directory contents. For example,

          ls -l
               -| total 12
               -| -rw-r--r--   1 jwe  users  4488 Aug 19 04:02 foo.m
               -| -rw-r--r--   1 jwe  users  1315 Aug 17 23:14 bar.m
     

The dir and ls commands are implemented by calling your system's directory listing command, so the available options may vary from system to system.

— Built-in Function: pwd ()

Return the current working directory.
