Basically I have a shell script that needs to perform some automated 
tasks over a network.  For example say i wanted to automate a login 
process.  I want to be able to write a script that reads from the 
output of telnet and then writes its responces accordingly outputting 
them to telnet.  is that possible in plain BASH?
