10 | .SH DESCRIPTION | |
11 | .I Learn | |
12 | gives CAI courses and practice in the use of UNIX. | |
13 | To get started | |
14 | simply type `learn'. | |
15 | The program will ask questions to find out what | |
16 | you want to do. | |
17 | The questions may be bypassed by naming a | |
18 | .I subject, | |
19 | and the last | |
20 | .I lesson | |
21 | number that | |
22 | .I learn | |
23 | told you in the previous session. | |
24 | You may also include a | |
25 | .I speed | |
26 | number that was given with the lesson number | |
27 | (but without the parentheses that | |
28 | .I learn | |
29 | places around the speed number). | |
30 | If | |
31 | .I lesson | |
32 | is `\-', | |
33 | .I learn | |
34 | prompts for each lesson; | |
35 | this is useful for debugging. | |

50 | The special command | |

53 | session. | |

55 | The | |
56 | .BI \- directory | |
57 | option allows one to exercise a script in | |
58 | a nonstandard place. | |
59 | .SH FILES | |
60 | /usr/learn and all dependent directories and files | |
61 | .SH BUGS | |
62 | The main strength of | |
63 | .I learn, | |
64 | that it asks the student to use the real | |
65 | UNIX, also makes possible baffling mistakes. | |
66 | It is helpful, especially for nonprogrammers, | |
67 | to have a UNIX initiate near at hand during the first | |
68 | sessions. | |
69 | .PP | |
70 | Occasionally lessons are incorrect, sometimes because the local version | |
71 | of a command operates in a non-standard way. | |
72 | Such lessons may be skipped, | |
73 | but it takes some sophistication to recognize | |
74 | the situation. |
