/users/courses/cs110/f01/PUBLIC/joi/1/bank
ls (list) directory contents
mars:/users/tnliu:> cd $CS110
mars:/users/courses/cs110/s01/PUBLIC> ls
classes/ examples/ handouts/ hw1/ joi/ src/

/ for directory
@ for link (your cs110 directory is really
elsewhere)
* for executable (you may not have seen one)
