Having issues with an expect script. I've been scripting bash, python, etc... for a couple years now, but just started to try and use Expect. Trying to create a script that takes in some arguments, and then for now, just runs a pwd command(for testing, final will be command I pass).
Here is the bash script:
#!/bin/bash
if [[ $# -eq 0 ]];then
echo "USAGE: $0 <dirname> <servername1> <servername2> ..."
fi
dirVar="$1"
shift
mypassword=`cat /home/chris/sshPush/.pass`
for i in $*; do
expect -d ./expect-pwd.exp $dirVar chris $i
done
#!/usr/bin/expect -f
set filename [lindex $argv 0]
set user [lindex $argv 1]
set server [lindex $argv 2]
set timeout -1
set exp_internal 1
spawn ssh $server
sleep 1
expect ^*/home/chris*
send "su - asa\r"
expect ^*sword:
send "password\r"
expect ^*$server*
#send -- "mkdir -p $filename\r"
send -- "pwd\r"
close
Here is the output I get from that:

It says it is sending the "pwd\r", but it never really does. I've also tried this with a mkdir and a touch command, not working. Almost like the connection is closing before it's able to send the command.
