在运行批处理脚本的Perl中，脚本需要STDIN

Question

In Windows, I want to run a batch script in perl. This batch script wants two inputs from the user, but I want these inputs to come from the perl script. I've tried doing an echo | batchscript but that only works for one input. Currently I'm implementing it like this:

chdir "C:\\folder\\folder\\folder";
`some batch script`;
`echo variable`;
`echo filename`;

Another way I tried:

chdir "C:\\folder\\folder\\folder";
`echo variable | some batch script`;
`echo filename`;

The variable and filename are the two inputs that the script prompts for before continuing. Neither works. Anything helps. Thanks

脚本从stdin中读取：

my $script_out = qx(printf "%s\n" variable filename | script.sh);
