LEARN(1)

NAME
learn - computer aided instruction about UNIX

SYNOPSIS
learn [ -directory ] [ subject [ lesson [ speed ] ] ]

DESCRIPTION
Learn gives CAI courses and practice in the use of UNIX. To get started simply type `learn'. The program will ask questions to find out what you want to do. The questions may be bypassed by naming a subject, and the last lesson number that learn told you in the previous session. You may also include a speed number that was given with the lesson number (but without the parentheses that learn places around the speed number). If lesson is `-', learn prompts for each lesson; this is useful for debugging.

The subjects presently handled are

    editor
    eqn
    files
    macros
    morefiles
    C

The special command `bye' terminates a learn session.

The -directory option allows one to exercise a script in a nonstandard place.

FILES
/usr/learn and all dependent directories and files

BUGS
The main strength of learn, that it asks the student to use the real UNIX, also makes possible baffling mistakes. It is helpful, especially for nonprogrammers, to have a UNIX initiate near at hand during the first sessions.

Occasionally lessons are incorrect, sometimes because the local version of a command operates in a non-standard way. Such lessons may be skipped, but it takes some sophistication to recognize the situation.
