expect and bash

[Alex_L]

Hi

I want to write a script with expect that is interactive.
Let's say in pseudo code:
#connect to a server
spawn ssh server.....
#let do something in a loop
#loop
#get some values
# read a
#grepping some output
# a=out|grep a
#use this as input
# send "Value=a\n"
#\loop

I need to know, how to interrupt the spawned process, doing some things in bash and continue with the spawned process, so that i turn in a loop, not every time logging for new.

Thanks.

Al
