First of all, I think it's great that we have all these new users joining the Forum lately and wanted to learn but a new user should do his/her own homework BEFORE asking questions such as this. UNIX has a thing ccalled man pages to guide us in learning new (and sometimes old) things. That's what we old-timers (Did I really say that?) usually check with when we have questions about commands and/or parameters. Who out there remembers all the options to ps? Well, at least I don't!

With that said, you should check man pages for find, du, sort, and head. The "|" is what we call pipe in UNIX. It essentially creates a channel between the command on its left and the command on its right that allows the command on its right to "do something" with the output generated by the command on the left of the pipe. If you want to learn more about this, any good UNIX book should get you what you need or just Google or Bing it.
