I have a setup file that has to be run silently like:
./setup < answerFile >> logfile
Where answerFile is basically has the input to the setup:
Is there a way in perl to open the command for input and print the answers to each question?
my $setup = "./setup";
my $answerFile = "./AnswerFile";
my $logFile = "./log";
open (IN, "<$answerFile") || die "can't open $answerFile: $!";
my @answerFile = <IN>;
open (SETUP, "| $setup") || die "can't run $setup: $!";
# stuff gets printed out then a question is displayed
# want to answer the question from $answerFile
print SETUP $answerFile[$i++];
Running the setup without the answerFile produces something lilke:
foo Server Installation, build spf-14-3-0_12326
WARNING: NIS Detected.
Please ensure that the services entry uses files,
otherwise this installation of foo Server Installation may no
WARNING: sudo is not installed or not on path.
foo Loader will not be able to login as
anyone other than the current user.
Checking for existing installations...
Please choose from one of the options listed below.
1. New Installation (default)
2. Upgrade /tril21/workarea/12/server
3. Upgrade /tril21/workarea/13.5/server
Enter choice (1-3): $answerFile
Please enter the name of your organization: $answerFile
Where would you like to install foo Server? : $answerFile
Is this even possible to do like this?
Currently - I'm just running a system on the command like so:
system ("$setup < $answerFile");
Which I do not think is ideal
Any guidance would be very appreciated.
