If the script is a purely command line program that takes its inputs from stdin, you can avoid IPC::open3 by feeding the required interactions to via a pipe.
Say the script requires two lines of input, like this one:
#! perl -slw
chomp( my $interact1 = <STDIN> );
chomp( my $interact2 = <STDIN> );
print "Got: $interact1 $interact2";
Then you can feed it the required inputs and retrieve its output like this:
C:\test>perl -E"$p = open I, '-|', '( echo fred & echo jim ) | interac
+t.pl'; say for <I>;"
Got: fred jim
This often will not work for programs that expect passwords.
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
RIP Neil Armstrong
