BASH shell script with Expect

Zones: Shell Scripting, TCL Scripting Language

Tags: expect, script, bash, shell

Hello all! I have been trying to put together a BASH script which uses Expect within the script. A parameter of another script gets passed to this BASH script, which then passes to the Expect script within. The problem is its not working. The parameter I beleive would get passed, but the Expect portion is failing. It seems to go into a constant loop with the second send command. It creates the stream but then tries again, and again.....never stops.

         
           
           
             #!/bin/bash
 
VLCHOST="192.168.1.240 4212"
PASSWD=admin
DIR=/home/vlc/videos     
VIDEO=$1
 
expect -c "
spawn telnet $VLCHOST
expect {
Password: { send \"$PASSWD\r\"; exp_continue }
> { send \"new stream vod enabled\r\"; exp_continue }
> { send \"setup stream input $DIR$1\r\" }    
}
exit
"
exit

Thank you both for replying. I did find a way to finish the script within BASH, only to end up passing the wrong variable. I figured out how to pass using expect only variable (argv?) and it passes the same variable as the BASH. So I believe I am still going about it the wrong way. I am using SATGUI from www.satisoft.com . What I end up passing in either case ends up being the username I enter when I start the SATGUI server. I'm not sure what to do at this point, but I thank you both for the help.
