# you may have to change the path of expect above.
# do a "which expect" in the machine you're on aand see what is the path...


# here's a small expect script that does the following - 
# 1> logs into a machine
# 2> executes a program
# 3> provides inputs to the program
# 4> logs out of the machine
# for more information on how to write expect scripts,
# read the unix manuals on expect & autoexpect (man expect)
# this is just an example, u don't have to startup ur client/server etc.
# in the same way.
