Background: At work, I came across a book titled "The Waite Group's UNIX Primer Plus"... it's apparently a 1995 publication (ISBN 0-672-22729-0) that covers UNIX v. 4.3. A nice piece of history!
Discussion: As I started reading it, I came across a utility called 'learn'... it's described on p. 65 of that book. It is apparently a command-line, interactive utility. To partially quote the book:
Question: I tried to do a bit of research. I know that FreeBSD's manpages do include manpages for the utility, but only for 4 sets of manpages (2.8 BSD, 2.9.1 BSD, 2.10 BSD, and 2.11 BSD), (and NOT 4.3 BSD or 4.4 BSD as that book claims)... here's the URL where I took the screenie. This 'learn' utility is not in base or in ports for present-day FreeBSD. So my question is: Does anyone know if there's an Open Source project that maintained that utility?

When you invoke 'learn', the system gives you an interactive lesson at your terminal. It presents information, asks questions, and tells you whether your answers are correct.
To use this utility, type
Code:% learn These are the available courses- C editor eqn files macros morefiles If you want more information about the courses, or if you have never used 'learn' before, type 'return'; otherwise type the name of the course you want, followed by 'return'.
