Using Telnet in a script

Hi All,

I was trying to use telnet in a script to access a certain processor on a certain port to view some processes. The problem is that when I use telnet the output is displayed for me.

The script is:
#!/bin/sh
cd /ahmed/ezzat/
rm ss7trace.log
touch ss7trace.log
chmod 755 ss7trace.log
telnet 172.16.0.9 8100
ps > result
quit

At the line of telnet I get an output:
Trying 172.16.0.9...
Connected to 172.16.0.9.
Escape character is '^]'.
U-Qtil>

but thats not what I want. I want the script to telnet to the processor then do ps and write the result in the result file then quits without giving me the output of telnet to type ps.

Can anyone help me regarding this, I will be so thankful.

Best Regards,
Ahmed.

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
attributes(5) WARNINGS
