When you open a telnet session in a script you must read the session prompts and write the replies. For example, you open a telnet session in a script and read the session and when you match the word 'Login' (or whatever) you write the user id. The same for password.

In other words, you automate in the script what you manually do at the keyboard. When you do it from the keyboard, you telnet, then wait for the login prompt. When you get the login prompt, you type the login. etc.

Writing a script is the same for telnet sessions, however instead of the keyboard, you echo (or write) in the script. Instead of seeing the login problem, you match the pattern in the script (your eyes, so to speak).

telnetrc(4)							   File Formats 						       telnetrc(4)

NAME
telnetrc - file for telnet default options DESCRIPTION
The .telnetrc file contains commands that are executed when a connection is established on a per-host basis. Each line in the file con- tains a host name, one or more spaces or tabs, and a telnet(1) command. The host name, DEFAULT, matches all hosts. Lines beginning with the pound sign (#) are interpreted as comments and therefore ignored. telnet(1) commands are case-insensitive to the contents of the .telnetrc file. The .telnetrc file is retrieved from each user's HOME directory. EXAMPLES
Example 1: A sample file. In the following example, a .telnetrc file executes the telnet(1) command, toggle: weirdhost toggle crmod # Always export $PRINTER DEFAULT environ export PRINTER The lines in this file indicate that the toggle argument crmod, whose default value is "off" (or FALSE), should be enabled when connecting to the system weirdhost. In addition, the value of the environment variable PRINTER should be exported to all systems. In this case, the DEFAULT keyword is used in place of the host name. FILES
