How to respond to system prompt Y/N ?

[MTek1240]

Hi everybody,

I am new to Perl and didn't find answer to my question, so here it is:

How do I respond to system prompt Y/N ?

I wrote a Perl script that connects to FTP server, locate .tgz file, download, unTAR, start installation proccess, BOOM!!


System prompt appears: do you want to reboot Y/N

I tried

system "y"; # doesn't work

should I use pause or wait during installation?

Thanks in advance

You can use the Expect module or

If whatever is being installed can be pre set with commands to provide "y" for all args that the download exectable is requesting.

What are u installing a perl module?

Thank you!

No, I won't be able to pre set files, it would be new builds of software.

I'll try to find information on Expect module and use it

Also, is it posible to somehow read the system and then use ' system "y\n"; '

Thanks

Expect" works for telnet and ssh, how are you conecting to the FTP server?

I use Net::FTP

There would be 2 prompts

* "Do you want to compress old files?" I need to respond with "y"

* "Do you want to reboot?" respond "y

Why not FTP the files over then telnet over to start the install process?? Net::Telnet will handle prompts.
