learn - Provides computer-aided instruction for the C shell
learn [-directory] [subject] [lesson]
command provides computer-aided instruction
courses and practice in the use of Tru64 UNIX.
Allows you to exercise a script in a nonstandard place.
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 questions 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 previous 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 debugging.
You can specify the following subjects:
files editor vi morefiles macros eqn C
There are a few special commands. The
session, and the
command tells you of your progress (where m
tells you more.)
command redisplays the text of the lesson and
lets you review
command prints the last
part of the lesson script used to evaluate a response, while
prints the entire lesson script. This is useful for debugging
lessons and might possibly give you an idea about what is expected.
To take the online lesson about files, enter: learn files
You are then prompted for further input.
