Is their an FTP command to get the server operating system? I am writing an FTP client for a small assignment (and to prove I can do it :P) and I need to know if the server is a Windows or UNIX server. I don't really have a WINDOWS FTP server to test it on, so its really just a guess.

Also, the "-a" filter is used in UNIX/LINUX to show all files. Will this command work in WINDOWS environments?

I think almost all Windows FTP server are mostly command set compatible with UNIX ones, except when treating text files that is. The only servers that don't follow the well established rule are djb's publicfile and the FTP server that come with an old version of IIS.
