done < telnet.txt
}

telnetrc

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

       $HOME/.telnetrc
