LEARN ABOUT OSF1

learn

learn(1)						      General Commands Manual							  learn(1)

NAME

       learn - Provides computer-aided instruction for the C shell

SYNOPSIS

       learn [-directory] [subject] [lesson]

       The learn command provides computer-aided instruction courses and practice in the use of Tru64 UNIX.

OPTIONS

       Allows you to exercise a script in a nonstandard place.

DESCRIPTION

       To  get	started,  enter learn; if this is the first time that you are invoking the learn command, you are guided through a series of ques-
       tions to determine what type of instruction you want to receive.

       If you have used learn before and left your last session without completing a subject, the program uses information  in	$HOME/.learnrc	to
       start you up in the same place you left off.

       To  bypass questions, enter a subject or lesson.  In order to enter a lesson, you must know the lesson number that you received in a previ-
       ous learn command session. If you do not know the lesson number, enter the lesson number as a subject.  The learn command searches for  the
       first  lesson  containing  the subject you specified. If the lesson is a - (dash), learn prompts for each lesson; this is useful for debug-
       ging.

       You can specify the following subjects:

       files editor vi morefiles macros eqn C

SUBCOMMANDS

       There are a few special commands.  The bye command terminates a learn session, and the where command tells you of your  progress  (where  m
       tells  you more.)  The again command redisplays the text of the lesson and again lesson lets you review lesson. The hint command prints the
       last part of the lesson script used to evaluate a response, while hint m prints the entire lesson script.  This	is  useful  for  debugging
       lessons and might possibly give you an idea about what is expected.

EXAMPLES

       To take the online lesson about files, enter: learn files

       You are then prompted for further input.

FILES

       Playpen directories.  Start-up information.
