[SOLVED] Installing java on linux using ssh

Issue

I want to install java on many computers using ssh so I want to write a bash script that will do (roughly):

for c in computers
do    
   scp jre--.rpm $c
   ssh $c 'sudu -s; chmod a+x jre--.rpm ; ./jre--.rpm; echo "success!"'
done

The problem is that during the java installation I need to "read" the notice and type "yes" at the end. How do I do it? Is there an easier way than "expect"? And if not how to I fit it in the bash script?

thanks a lot

Solution

expect is the way to go (thanks http://www.dnmouse.org/java.html):

   for c in computers
   do    
       scp jre--.rpm $c
       ssh -t $c 'sudo -s; yum -y install expect; sudo chmod a+x jre--.rpm'
       ssh -t $c '/usr/bin/expect -c \
       "set timeout -1; spawn ./jre-6u13-linux-x64-rpm.bin; sleep 1; send -- q\r; sleep 1; send -- yes\r; expect eof"
       echo "success!"'
   done
