The error message is self-explanatory.

A brief examination of the code tells me that you haven't got `expect` installed. Please verify that you do have `expect` on the machine, and if necessary, use the full path to `expect` if it is not in your $PATH.

I'm not sure why the error indicates the error is on line 15, but then, there are many cases I've seen where shell gives error line# that is not actually where the error is - but verify that you have `expect` first. If not, install it and try your script again.

NOTE: It may help us if you tell us what Linux OS you are using (since you posted from Windows, we cannot even guess) but I believe `expect` is normally installed on Linux in general.

Please verify that `expect` is installed on the machine.

Ok, maybe this will "do the needful"

Your script clearly says it can't find the "expect" command.
Since it can't find it, that means it's probably not installed
INSTALL IT

Arre dhiren,

(1) expect is the name of a package that has to be installed before testing the syntax of your script.

(2) If you tell which distro (distribution) you are using, we may be able to tell you how to check if expect is installed or not and if not installed, how to download and install under linux.

(3) Are you getting internet from linux?

End

You could see if it were installed just by running the `expect` command from your shell, or running `which expect`, or by asking your package installer, which I believe is called "yum". Since I don't use or know about "yum", and I don't use CentOS, you will have to await help on that from a yum/CentOS user; but the yum manpage should have a good explanation of possible commands. To read the man page:

Code:

shell$ man yum

Here's what I'd do meanwhile, to see if `expect` is installed:

Code:

# let's ask where expect is located:
shell$ which expect
/usr/bin/expect    << tells me that `expect` is in /usr/bin/

# Let's try starting expect command-line:
root@reactor: expect
expect1.1>     << Look~ the expect1.1 command interpreter has started, so I have `expect`. (Type "exit" to quit)

Here's a yum command to install `expect` - but as I said, I haven't a clue if this is the right command, so either read the instructions, or await further help, or try this at your own risk:

Code:

# For RHEL/OEL/Centos version 5:

shell$ sudo yum install expect expectk

I got that command from a post half-way down this page here, which I found using Google:

Finally, here's a page from the CentOS wiki/main site, which you can go to and select an information topic about CentOS. The first subject on the list is dealing with CentOS repositories - repositories are where you get your software packages from:
