We'd like to use the following bash variables into an telnet session and work with the output of the telnet in the bash:

Bash:

$me=Tester111
$myid=XXXWWWZZZ

Telnet:

login serveradmin PW
msg OK (output)
use sid=1
msg OK (output)
clientgetids cluid=$myid
cluid=XXXWWWZZZ clid=2 name=Tester111 (output)

Then bash again:

...
Workings with the clid=2 output
...

We need telnet cause it's used in teamspeak. How to start an telnet session in an bash script and handle it?

Can you use the `expect` program? [This question](http://stackoverflow.com/questions/1538444/using-conditional-statements-inside-expect) has some examples of how to use expect with telnet. – Mark Plotnick Mar 09 '17 at 19:43
Can u handle variables with expect? Seems like it just waits for the output u define. That's not what we work with. – Frank Stone Mar 09 '17 at 19:49
Yes. You can get and set environment variables, and examine the output that the spawned command generates. For an example of the latter, see http://stackoverflow.com/questions/20884435/how-to-store-output-in-a-variable-while-using-expect-send-command. – Mark Plotnick Mar 09 '17 at 20:14
I'll give it a try, thx alot! – Frank Stone Mar 09 '17 at 20:17
`send "clientgetids cluid=$env(myid)\n"` will send the variable – Diego Torres Milano Mar 09 '17 at 20:21
