MySQL Need help in implementing expect
Hello All,

I am trying a shell script for automatically login to test servers and pulling the output of top command from all using expect.

----snippet of code ---
Code:
#!/usr/bin/expect -f
#!/bin/bash
server1=10.251.222.51
server=("$server1")
i=1
for exp_server in ${server[@]}; do
 expect -c "
 spawn ssh @rtq1@$server
 expect {
 "*password:*" { send $Password\r\n;
 expect "*[/home/rtq1]"
 send "last reboot > file.txt"
 expect "*[/home/rtq1]"
 }
 eof {exit}
 exit
 "
 let "1=1+1"
 done

This is throwing error as shown below
==================================
Code:
$ ./sshlogin
invalid command name "server1=10.251.222.51"
    while executing
"server1=10.251.222.51"
    (file "./sshlogin" line 3)

=====================================
Please help me out in finding the error or give me another logic which can do the work...

Thanks
RR

If you can configure passwordless ssh between the machines, it will be lot more easier and secure. Any thought on that?

No. Passwordless login will not allow in my test servers

Try this...
Code:
#!/bin/bash
password="password"
server1="10.251.222.51"
server=($server1)

for exp_server in ${server[@]}; 
do
        expect -c "
        spawn ssh $exp_server last reboot > /tmp/log
        expect \"*password* \" { send -- \"$password\n\" }
        interact; exit" 
done

We strongly advice you to use passwordless ssh!!!
