FTP command Overview

There are a lot of FTP software, but we still need to implement it in some advanced applications! Favorites:

========================================================== ======================================

FTP: file transfer protocol. Let's talk about his function first, mainly to transfer files from the computer running the FTP server. Interactive use. Note that FTP commands can be used only on machines with TCP/IP protocol installed.
Command Format: ftp [-V] [-D] [-I] [-N] [-G] [-S: Filename] [-A] [-W: windowsize] [computer]

Let's talk about their meaning.
-V does not display Remote Server Response
-N: automatic login upon the first connection prohibited
-I disable interaction prompts during transmission of multiple files
-D allow debugging and display all FTP commands passed between the client and the server
-G does not allow wildcard characters in the file name, which means wildcard characters can be used in local files and pathnames.
-S: Filename specifies the text file containing the FTP command. These commands are automatically run after the FTP command is started. The added parameter cannot contain spaces.
-A uses any local port when binding a data connection
-W: windowsize ignores the default 4096 transmission buffer.
The IP address of the remote computer to connect.

I have understood the above and talked about some specific commands. I personally think that although the tools are very convenient to use now, it is still very useful to understand these commands in many places, just like the command prompt in NT

You can familiarize yourself with the commands. In fact, there are a lot of FTP software, which is very convenient, but it is impossible to say that these commands are useless, like in windows, the command prompt is retained. in particular, FTP software cannot be used in many places ,.? Where.
For example, I have seen a hacker who finds an FTP user and obtains the admin intrusion column. He will use it.
