Hello, I'm trying to automate the login of ssh and then interact when a prompt is reached.  I don't know what I'm expecting while logging in (password prompt or ssh key) so loop through these.  This script prompts you for a username, password and host, then runs expect.  I want to exit the login loop once a prompt is reached,  run the "uname" command and then (hopefully) interact.

code button not working for me, will these code tags work?

Code:

#!/bin/ksh #get username, password and host information from user username= password= host= clear  #clear screen until [[ "$username"  != "" ]];do  print -n "Enter username: "  read username done until [[ "$password" != "" ]];do  print -n "Enter your password: "  stty -echo  read password done #return echo to terminal stty echo until [[ "$host" != "" ]];do  echo ''  print -n "Enter remote host: "  read host done #initiate ssh connection and loop through possible prompts (accept key or password) # once prompt is reached run uname command and then interact expect_output=$(expect -c "  set prompt "(%|#|\\\$) $"      ;# default prompt  set timeout 10  match_max 100000  spawn ssh $username@$host  expect {    stty -echo    "*yes/no*" { send \"yes\r\"; exp_continue }    "*assword:" { send \"$password\r\"; exp_continue }    stty echo      $prompt { send \"uname\r\" }  }  interact  exit } #display output from expect echo "" echo $expect_output #clean up username= password= host= expect_output= #exit script exit0

You might find it easier to put your expect script into a separate file and test it on its own rather than embedding it within a Korn shell script.  Tcl quoting is bad enough without adding a ksh level too!

I have put my code in a separte expect script and it still fails because the issue is the expect loop, not ksh.  If I put the following into expect it still fails, again, not sure how to exit expect loop and initiate interaction.  Are there for or while loops in expect?  I could possbile do something like this:
for (i=0; i<2;i++):  then loop through twice and automatically exit...??

Code:

set timeout 10 match_max 100000 spawn ssh username@hostname        stty -echo        expect {          "*yes/no*" { send \"yes\r\"; exp_continue }          "*assword:" { send \"$password\r\"; exp_continue }          "*$" {interact}          }        stty echo        exit      ")

exp_continue tells it to loop.  If you remove the exp_continue, it will break out of the loop.  And if you want to keep expecting until you have some counter up to (say) 2, write of the form

set counter 0
while {$counter < 2 } {
expect ..... to include incr counter were appropriate
}
