You aren't seeing the output from the 1st telnet session because the script is reading it instead of displaying it on the terminal. I was mistakenly expecting to see only PWR0 or PWR1 on the 1st (and only) line of output from telnet. Let's try a slight modification:
Code:
#!/bin/ksh
echo '*** Request amp status...'
{ sleep 2
echo '?p'
sleep 2
} | telnet 192.168.1.155 | while read power
do printf "%s\n" "$power"
if [ "$power" = "PWR1" ]
then echo '*** Amp power is on; send mute command...'
{ sleep 2
echo MZ
sleep 2
} | telnet 192.168.1.155
echo '*** Amp should be muted now.'
fi
done
This should let us see the output from both telnet sessions (assuming we do get a line from the 1st session that just contains "PWR1").
(I normally use ksh, but this script should also work with bash.)
Sorry I couldn't react earlier! I really like that you are helping me, but I've been busy last night so I couldnt try it any sooner(wife nagging ) .
I've tried you script and adjusted some tiny bits. Strange thing is that the pioneer amp gives a answer on the ?p question with PWR0, instead of 1... which you would expect. Anyway, I've tried your script it gave me this:
Code:
pi@domoticzpi ~ $ . /home/pi/domoticz/scripts/bash/versterkeruit1.sh
*** Request amp status...

PWR0
Connection closed by foreign host.
So there is something happing! but I it wont go any further. When I look at the telnet session closely it does not only give me the PWR0 answer sometimes, but sometimes a line with numbers. I guess this happens when something changes inside the amp. some sort of feedback. Then again, the script does not go any further so maybe this is not the problem.
I found a site which describes some kind of scripts which stores the output. I don't know if we can use this?

Hi Guys,
How do I write the script for the following
telnet 192.168.1.100 9002
if the result is less than 1 second. The script should say as port open
if the result takes more than 3 seconds. The script should display as port closed.
Thanks,

Hi all,
I would like to write a ad hoc shell script that would allow me to do some telnet tests to multiple IP's and ports at the same time . So, I want to determine which one is successful and which one fails. So, basically I would like the shell to spawn the telnet test and to break out of... (3 Replies)
