snreddy_gopu has asked for the wisdom of the Perl Monks concerning the following question:

Hi all, I have one shell script which needs runtime input. I have run this script through another shell script as follows 
./setup.sh << EOI
a
EOI

Now I want to run that setup.sh shell script through perl script instead of another shell script.

    I think you want piped open: 

    open my $fh, "| ./setup.sh" or die $!;

# print $fh "$_\n" for qw(a b c ...);

    When you then say print $fh ..., the shell script gets the data on stdin, as it would from your current heredoc.
