Hello, I am trying to create a child process to execute cmd.exe. When I used process::Command to execute "cmd", the process of "cmd" was created one by one and never stopped. However, when I used process::Command to execute other exe, nothing strange happened. Is there any advice? Thanks Code: std::process::Command::new("cmd").args(&["/C", "dir >> 1.txt"]).creation_flags(0x00000010).output();
