After properly configuring FileZilla to communicate between servers, I tried to automate some transfers using Windows builtin FTP support

```
ftp -s:command.file

```

I replicated FileZilla's client commands verbatim (using *literal*) and I get this weird phenomenon:

Successful transfer using FileZilla

This is my attempt, using FTP

**What should I do to replicate FZ? What differs the two FTP clients?**
