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

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
