Perl: answering automatically to install questions
Hi everybody,
I have been looking for an answer to this issue both on google and on the forum, but I couldn't find anything. please help me
As part of an automated (in perl) install of Solaris 9, I would like to be able to answer automaticaly to the question the installer asks.
Example:
/> /cdrom/cdrom0/s0/Solaris_9/Tools/Installers/liveupgrade20
...
<Press ENTER to continue>
...
<--[21%]--[ENTER To Continue]--[n To Finish]--> n
...
Enter 'y' to accept the license agreement. Enter 'n' to decline the license
agreement and exit the install. Y
...
<Press ENTER to continue>
etc...
Here, I woud like to automatically answer via my perl script that is the following sequence: "enter" then "n" then "y" then "enter"
Is it possible in perl? Can I do it without using threads? Do I have to make a dedicated perl script running in the background that will detect the prompts and answer them? Or maybe a shell script could do it ???
in summary: HELP ME PLEASE
Thanks !!!!
