After logging into your account on www.rochester.edu, change into the directory where your home page files are stored using the cd dirname command, where dirname is the name of your Web directory.
You can type ls to list all the files and subdirectories in that directory (See the Unix Guide for more commands). When you know the file name of the file you want to change, and you are in the right directory, type pico filename to edit the file.
Other commands are simply listed at the bottom of the screen.
