I am trying to write a script to telnet from a power broker jumpbox to
a host. The hosts are listed in a numbered menu that changes
periodically. The list below is similar to my actual list. If i want
to log into host pear.domain.com, I would select "3". If the list is
modified, pear may become option 4 or 2. How can I have expect match
pear.domain.com and return it's current menu option?

Please choose a system:

Untested:

expect {
-re {(\d+)\s+pear\M} {
set pear_num $expect_out(1,string)
exp_continue
}
-re {Please choose a system:}
}
if { ! [info exists pear_num]} {
error "No fruit for you! Got the prompt without finding a pear"
}
exp_send -- "$pear_num\r"

awesome, i will try this. my crude solution was:

expect {
"1 pear" {send "1\r"}
"2 pear" {send "2\r"}
"3 pear" {send "3\r"}
"4 pear" {send "4\r"}
"5 pear" {send "5\r"}
}

it worked but is inefficient. I will post the results.
