管道写入

$pid = open $writeme, "|-", "program", "args";
print $writeme "hello\n";            # program will get hello\n on STDIN
close $writeme;                      # program will get EOF on STDIN

IPC::Open2 同时输入、输出流：open2(my $reader, my $writer, $program);

IPC::Open3 控制输入、输出、错误流：open3($write_me, $read_me, $errors, "program to run");
