An old Unix spell book called,Unix Text Processing that is still useful today, even on Ubuntu, is available here; http://oreilly.com/openbook/utp/ download PDF, open with Evince, read and enjoy!
grep on page 301, uniq on page 323
Text Processing in Linux should also be helpful, http://www.brezeale.com/technical_notes/text_processing.shtml
