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 "
/usr/local/bin/expect << EOF
### ssh to jump server

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

expect "*#"
send "term len 0\r"
expect "*#"

expect "*#"

send "exit\r"
}
### Exit jump server
