Re: ftp mdtm: invalid command
Sorry if it's a silly question, but wouldn't it be better for the FTP client to support the command names as standardized in IETF RFCs?

Re: ftp mdtm: invalid command
Thanks for your suggestion, it works great! I also found the "quote" command a useful alternative. -Felipe.

ftp mdtm: invalid command
Greetings. Thank you for the excellent inetutils. I'm using the FTP utility, which supposedly supports the MDTM command (as per section 21.1 Standards of the documentation): https://www.gnu.org/software/inetutils/manual/inetutils.html However, when I try mdtm, it complains: "invalid command". For testing purposes, I've used the quote command: quote "mdtm myfilename.ext" which returns a timestamp correctly. ftp> mdtm 20230518T213000Z.gps.new ?Invalid command ftp> quote "mdtm 20230518T213000Z.gps.new" 213 20230521012942 So, the server recognizes the command correctly. Am I missing something? Thank you! -Felipe.
