When mail notification is turned on, the bell rings each time you receive mail, and the first few lines of the message

Dear O'Reilly,

I am a technical writer/editor, with experience in Unix Shell Programming, a degree in Mathematics and Linguistics, and over 25 years experience as a technical translator, editor, and technical writer. I would be interested in free-lance/consulting projects, editing and/or proofreading books and other manuscripts.

I used an earlier edition of Unix in a Nutshell to learn Shell Programming and recall finding minor misprints in that edition, and thought of glancing through the fourth edition to check for errors, misprints, etc. The list below is from a very brief scan of the volume.

Please let me know if the formatting here is unclear.

Sincerely,

Robert Silverman

P.S. Incidentally, all occurrences of "few" and "several" should be replaced by actual numbers (or it should be stated that the actual number can be specified, depends on environment, etc.)
