B. W. Kernighan and M. E. Lesk, LEARN - Computer-Aided Instruction on UNIX

Is this program somewhere available?

In an old book on Unix, I read about a command line program called learn, which could be used as a tutorial to Unix.

You can find further information but unfortunately no source on it on https://itservices.usc.edu/unix/commands/learn/.

There is also information about it on https://www.unix.com/man-page/bsd/1/LEARN/.

My question therefore is, where I could find the source (in case it is open sourced) or even better a package of it for current Linux distributions.

There is a repository on GitHub about it https://github.com/chettrick/learn, but if someone knows an additional source, I would be highly interested. The code available there gives me the following error: Makefile:33: *** missing separator.

  • While an interesting historic curiosity, I can pretty much understand in a world of graphical presentations, web and mobiles, why a "learn" text console command won´t be as valuable as it used to be. But I digress. If you enjoy the idea of learn search for vilearn too. – Rui F Ribeiro May 29 '18 at 7:32
  • Thanks a lot for hint. I certainly agree, but I would say that the best place to learn how to use the Unix command line is the Unix command line itself. – NicolasBourbaki May 29 '18 at 7:47

It’s also available in the Unix history repository, e.g. in the 4.1c BSD release (source code, man page), and on the Unix Tree at TUHS (source code, man page). The lessons themselves are available in V7; are contained in archives which are extracted by the Makefile.

The original V7 version is available under a BSD license with the advertising clause, so the license isn’t much of an issue.

If someone wanted to package this for a modern distribution, the lessons would really have to be updated...

  • Perfect, this was the link I was looking for. – NicolasBourbaki Jun 2 '18 at 13:04
