"Comparing files based on size is stupid."

Maybe yes, maybe no.

"I do, siz is not listed as a command. I'd have thought you'd have learned from previous failures to link to valid documentation which backs up your claim."

Commands may be abbreviated. Commands are:
That's the second time I've articulated the command. As such, in neither case was the man page required.

UPDATE: I forgot to mention; the ftp man page I cited in the comment you quoted, does mention size.
Best wishes.

    "That's the second time I've articulated the command. As such, in neither case was the man page required."

    Nope all you posted this time was:

    Commands may be abbreviated. Commands are:

    There's nothing about the command in question. Also, why link to documentation at all if it doesn't provide the information you claim it does?

    "Maybe yes, maybe no."

    The answer is no, but thanks for trying to argue that black is white. Your belief that comparing files by size can tell you that the file contents is the same is fundamentally wrong.

    Regardless, my statement you "corrected" was valid. FTP does not have a way to compare files, it may (system dependant) have a method for reporting the size of a file, but there is no way to provide ftp a local and remote file to compare, size or anything else.

    Update: s/believe/belief/

      "There's nothing about the command in question. Also, why link to documentation at all if it doesn't provide the information you claim it does?"
      Please see my update above (forgot to mention it).

      It does

        And you wonder why people don't understand you? Continuing to claim that your "correction" or using the file size as a basis for contents comparison is frankly ridiculous.

      OK. This is getting ridiculous. marto, just for you, I'm going to update this post with a bit of history on ftp. But, for now, please note; ftp does, and always has provided all the tools necessary to fairly accurately compare remote files, to local files. There has always been a wealth of commands available within the ftp command set. While you wait, you might look at the commands I've already listed, to imagine the possibilities. Here's another link to the same man page I posted 2 times prior, that lists the commands I've been referencing: ftp.

      I'll be back... :)

      UPDATE (as promised)
      I had intended to write up a history on ftp, but for the purpose of this thread, the following link summarizes things quite well, I think. Please review: FTP Subcommands
      Here's another link that includes a fuller set of commands: ftp commands

      Best wishes.

        I said:

        "FTP is for transfering files, it has no ability to compare them."

        You responded:

        "Correction; ...."

        Then told us how size can (if available) tell you the remote size of a file. This does not compare the size to anything. Also comparing the size of two files does not, contrary to your repeat claim, mean that the contents of the files are the same.

        Your correction was invalid, your assertion that files being the same size is somehow a comparison of their content is invalid.

        You could have provided a clear response first time, proving your claim. As usual, that didn't happen.
