Expect script to read file line by line
I have an expect script which is run inside a bash script. I am trying to ssh to a jump server then from the jump server telnet to each router in a file list and run the same command. I tried many ways but down not read the router list file for some reason.
I get the following error:
wrong # args: should be "read channelId ?numBytes?" or "read ?-nonewline? channelId"
while executing
"read "

Code:
/usr/local/bin/expect << EOF
 
### ssh to jump server
spawn /opt/SBCssh/bin/ssh test@192.168.1.254
match_max 100000
expect "*?assword:*"
send "${password}\r"
send "\r"
expect "*$"
 
### read router list file into variable
set fd [open hostlist r] 
set hosts [read $fd] 
close $fd
 
### From jump server telnet to each router in hostlist
set data [split $hosts "\n"]
foreach line $data { 
spawn telnet ${line}
expect "*login: "
send "${username}\r"
expect "Password: "
send "${password}\r"
expect "*#"
send "term len 0\r"
expect "*#"
log_file /tmp/${line}.output
send "show hard\r"
expect "*#"
log_file
send "exit\r"
}
 
### Exit jump server
set timeout 5
send "exit\r"
EOF

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

 *

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
