Linux expect expecting a hyphen in the prompt

So, I have an expect script that goes out to an HPE virtual connect module to run a show all command. However, when I am "Expecting" the prompt "->", Im getting an error:

bad flag "-> ": must be -glob, -regexp, -exact, -notransfer, -nocase, -i, -indices, -iread, -timestamp, -timeout, -nobrace, or --
while executing
 "expect "-> ""
(file "./expect_vc_showall.ziUzpF" line 10)

Here is my code:

 #!/usr/bin/expect -f
 set timeout 60
 set ip_hostname [lindex $argv 0];
 #log_user 0
 spawn ssh Administrator@$ip_hostname
 expect {
     "*yes/no*" { send "yes\r"; exp_continue }
     "*assword:" { send "password123\r" }
  }
 expect "-> "
 send "show all\r"
 #log_user 1
 expect "-> "
 send "exit\r"

I have tried to use expect -- "-> " but that just brings me to the prompt and then dies.

Here is what the prompt looks like:

 GETTING STARTED: 

 help           : Displays a list of available subcommands 
 exit           : Quits the command shell 
 <subcommand> ? : Displays a list of managed elements for a subcommand 
 <subcommand> <managed element> ? : Displays detailed help for a command 

 ->

If I just do a expect "> ", it dies at the first subcommand text.

Any ideas how to get this to work?

Thanks! Joe

The default pattern type for expect is a glob, and there is an explicit flag for that:

expect -gl "-> "

However, your pattern has no glob characters, so you could also use the exact flag:

expect -ex "-> "

You can do

expect -- "-> "

or use a glob pattern that doesn't start with a hyphen (much messier)

expect {[-]> }
