WHAT YOU SHOULD KNOW

As a minimum you should be familiar with ASCII terminal turn-on and setup. If you have a printer connected to your UNIX System, you should have some general knowledge about its page and print size. If you are using a modem to connect to your UNIX System, it is advisable to learn how to operate it.

Headings within each module are BOLDFACE and uppercase or ITALICS and uppercase. All boldface strings are literals that you are to type as they appear. Some of these are examples, requiring files that may not exist. Italic print usually specifies strings you are supposed to substitute in commands or the names of files or special phrases.

You must know your terminal type to use some of the UNIX commands. You may have to ask your UNIX system administrator or some other experienced UNIX user.

Finally, you should be familiar with your keyboard. If the keys on your keyboard have special symbols instead of words, use the following table to see how they are referred to in this book.

Key Name	Character Sent	Keyboard Symbol
Return	Ctrl-M	Return, Carriage Return, or <--!
New-line	Ctrl-J	Line-Feed
Backspace	Ctrl-H	<--
Tab	Ctrl-I	|<--
		-->|
Shift	Capitals/Symbols	Shift,

ENVIRONMENTAL ASSUMPTIONS

You will need to have the system administrator set up your account and answer the following questions. Many system administrators will provide this information to you without asking. The defaults used in this book are given in parentheses.

1.  What is my user name or login name? (mylogin)

2.  What is my password? (imauser2)

3.  Which key transmits a command to the system? (Return)

4.  Which key will erase a character? (# or Ctrl-H or DEL)

5.  Which key will kill an input line? (@ or Ctrl-X or Ctrl-U)

6.  Which key interrupts program execution? (Del or Ctrl-C)

7.  What is the termcap or terminfo name of my terminal? (vt100)

8.  Which shell will I be using? (ksh, i.e., the Korn shell) The notation of the shell, ksh, used throughout this book are references to the Korn shell. The Korn shell is a super-set of the standard Bourne shell (sh). Most BSD systems supply the sh and csh. The version of the sh on BSD is usually ancient, UNIX Version 7.

2.  The HOME directory for mylogin is /u1/ts/mylogin.

3.  The user ID for mylogin is 101, the group ID is 40.

4.  Various other user names are used throughout the book. Substitute valid user names in place of these names when necessary.

5.  The prompt (PS1) for mylogin is cj>, the secondary prompt (PS2) is cj>?.

6.  Turn to Module 2 to continue the learning sequence.
