Hello,

I'm having an issue with scripting expect and I was hoping someone could help me out. I'm scripting a telnet session connect, and I can't get the "expect" command to work correctly on the prompt, which is "~ $ ".

I think expect is getting confused by the $.

Heres the script:

#!/usr/bin/expect -f
set timeout 10
spawn telnet $argv
expect "login:"
send "mylogin\n"
expect "Password:"
send "mypass\n"
expect "~ $ "
# Send some commands
close

I've tried expect "~ \$", expect \$ and a few other escape permutations but the script just stops working after the prompt comes up. Thanks for any help!

Expect might or might not try to do variable expansion. Just te be sure, use single quotes: '~$'.

Also, at the start of you script say:
exp_internal 1

It will tell you exactly what Expect sees and tries to match.

Hope this helps

Thanks!

I was able to get it working by using that debug info from exp_internal. I still couldn't get it to recognize the whole prompt, but was able to get it to recognize the $ at the end which is enough for my purposes.

Single quotes didn't behave as described at all however. Not sure what the issue is there.

I am using variables and I am having a hard time getting my script to recognize the $ at the command prompt. I have been writing scripts using scp and sftp to get around this right now but...

Could you please post your solution to this problem.

Thanks,
jason

the solution is to use two forward slashes like so:

"\\$"

then it will look for the $ sign.
