Expect Script Help

[pareshan]

I have a ksh script which I have written but needs to change it to expect script so that I can automate it but dont know much about expect and while I tried its not working
can anyone help me on this plz, how can i conver that into expect script

here is my script which basically checks first and copy and untar the installation files and install fixpack which is just for one server and i have to copy it to all the servers to do it and while doing it ask for password as ssh is not setup for the accounts im using and I am told its not supposed to be setup for this account so that there is no way i can set up ssh for this account.

My script runs fine and install fixpack in one server provided i enter the password manually when it prompt for.

But I am trying to do something like expect script which can scp this script to all the boxes and can install the fixpack without prompting me for password or any other way does the job i mentioned.

I have done simple expect script only and couldnt figure out how to do for this one.

Could anybody help me plz. I will appreciate any help.

I'd seriously consider exchanging keys so ssh / scp can work without the password.

if not, then something similar to the following might work:


#!/usr/local/bin/expect --
spawn
expect "Password:"
send "password\r"
send "\r"

============

fix "Password:" to match the prompt you get. substitute real password for "password\r"

this can be further scripted to run thru the above (once fixed / working) with servername / password pairs.

my choice would be passwordless ssh however, as its more secure, and once setup, its dead easy to use.

As far as I see your necessity, You would better use TCL language, it seems very good especially in use this type of script, both condition check and automated telnet remote machine.. you can also use expect inside in TCL since they are compatible to work together.
