Help required on expect scripting
I am trying to write an expect script for remote server login. At some point of time I need to telnet based on the output of grep command. Based on the output I need to select the ip address of the server. How can I write an expect script for the same. The output of the grep command is as follows:

172.24.132.2 typhoon-base-active typhoon-base-db-primary
10.42.1.72 sca-ca1-0-datacallp-activeirm
10.42.1.4 sca-ca1-0-datacallp-inactiveirm
10.42.1.73 sca-ca2-0-datacallp-activeirm
10.42.1.9 sca-ca2-0-datacallp-inactiveirm
192.168.24.11 shmm-ptp-active

I need to select the activeirm on ca1 i.e. the second one in the above list. How can I write a script to select from the out of grep command?

telnetd

telnetd(8c)															       telnetd(8c)

Name
       telnetd - DARPA TELNET protocol server

Syntax
       /etc/telnetd

Description
       The  server  supports the DARPA standard TELNET virtual terminal protocol.  The TELNET server is invoked when receives a connection request
       on the port indicated in the TELNET service description.

       The server operates by allocating a pseudo-terminal device for a client, then creating a login process which has  the  slave  side  of  the
       pseudo-terminal	as stdin, stdout, and stderr.  The server manipulates the master side of the pseudo terminal, implementing the TELNET pro-
       tocol and passing characters between the client and login process.

       When a TELNET session is started up, sends a TELNET option to the client side indicating a willingness to do remote echo of characters,	to
       suppress  go  ahead, and to receive terminal type information from the remote client.  If the remote client is willing, the remote terminal
       type is propagated in the environment of the created login process.  The pseudo terminal allocated to the client is configured  to  operate
       in cooked mode and with XTABS and CRMOD enabled.

       Aside  from  this  initial  setup, the only mode changes will carry out are those required for echoing characters at the client side of the
       connection.

       The server supports binary mode, suppress go ahead, echo, and timing mark.  It also allows a remote client to do binary, terminal type, and
       suppress go ahead.

Restrictions
       Some TELNET commands are only partially implemented.

       The TELNET protocol allows the exchange of the number of lines and columns on the user's terminal, but does not make use of them.

       The terminal type name received from the remote client is converted to lower case.

       The server never sends TELNET go ahead commands.
