Shell Programming and Scripting

expect module is not installed in client unix box. so i thought of auotmating it as per my first post. but it is taking as empty charecters for password. infact iam able to login manually and run some batch script in windows but wheni automate it with the script as pe my first post its not working.
but now i just want to make sure if expect module is installed then can we make use of spwan and send commands. or we need to install speratley anything to make those send and spwan command work.

The login process will empty the input buffer before reading the password you type. I suspect it was designed this way to stop people automating login.

Of course, where there is a will to automate, someone usually achieves it, hence why expect was created. Without a tool like expect on the client side, you will not be able to automate a telnet login. An alternate is to set up services to accept rlogin, rsh/resh/remsh or ssh.

I have automated telnet with a ksh script. Here is the first time I did that...need script for passwd , can't use expect tool - Page 3 | Unix Linux Forums | Infrastructure Monitoring

It's clunky, but it worked.

ya but only thing is Expect is enough ? or we need to install send and spwan explicitly?

send and spawn are part of the expect language and not something that needs to be installed. Think of them like @sum and @avg are to Excel.

Earlier it was asked if you start from the unix client and type telnet pchost can you then manually type in a user and password and get your vbscript/batch command (s) to run? If you can do all this OK now and all you need is something to automate this already-working process then expect is fine.

If you can't do this manually expect will do nothing to help as it's just a tool to automate a manual process.
