This article introduces the relevant knowledge of "what are the FTP commands under DOS". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

FTP command is one of the most frequently used commands for Internet users. Whether you use FTP under DOS or UNIX operating system, you will encounter a large number of FTP internal commands. Familiar with and flexible application of FTP internal commands can greatly facilitate users. For current dial-up users, if ISP provides shell to use nohup, then ftp will be your most economical way to use download. The command line format of ftp is: ftp-v-d-I-n-g [hostname]

-v displays all response information for the remote server.

-d uses debug mode.

-n restrict automatic login of ftp, that is, do not use .netrc files.

-g cancels the global file name.

The internal commands used by ftp are as follows (where parentheses indicate optional):

1! [cmd [ARGs] executes interactive shell in the local machine, and exit returns to the ftp environment, such as! ls*.zip.

2. Macro-ame [args] executes the macro definition macro-name.

3.account [password] provides additional passwords required to access system resources after a successful login to the remote system.

4.appendlocal-file [remote-file] appends local files to the remote system host, or uses the local file name if the remote system file name is not specified.

5.ascii uses ascii type transport.

6.bell the computer rings once after each command is executed.

7.bin uses binary file transfer.

8.bye exits the ftp session process.

nine. Case converts uppercase to lowercase letters in the remote host file name when using mget.

10.cd remote-dir enters the remote host directory.

11.cdup enters the parent directory of the remote host directory.

12.chmod modefile-name sets the access method of the remote host file file-name to mode, such as chmod 777 a.out.

13.close interrupts the ftp session with the remote server (corresponding to open).

When 14.cr transfers files in asscii mode, it converts carriage return line feeds to return lines.

15.delete remote-file deletes the remote host file.

16.debug [debug-value] sets the debug mode to display every command sent to the remote host, such as debup3. Setting it to 0 means canceling debug.

28.macdef macro-name defines a macro that ends when a blank line under macdef is encountered.

29.mdelete [remote-file] deletes the remote host file.

30.mdir remote-files local-file is similar to dir, but can specify multiple remote files, such as mdir*.o.*.zipoutfile.

35.modtime file-name displays the last modification time of the remote host file.

36.mput local-file transfers multiple files to a remote host.

37.newerfile-name if the modification time of the file-name on the remote machine is closer than that of the file with the same name on the local hard disk, the file is retransmitted.

38.nlist [remote-dir] [local-file] displays a list of files in the remote host directory and stores it in the local-file of the local hard disk.

39.nmap [inpatternoutpattern] sets up the file name mapping mechanism, so that when a file is transferred, some characters in the file are converted to each other, such as nmap ¥1. ¥2. ¥3 [¥1, ¥2]. [¥2, ¥3], then the file name changes to A1, a2 when the file a1.a2.a3 is transferred. This command is especially suitable for cases where the remote host is a non-U-Nix machine.

So how do you use these commands to improve efficiency? Let me give you an example of how to use fttp to implement

Download in the background, suppose your ISP provides you with shell and you can use nohup, you want to use fttp.downlo

Ad.com/pub/internet/ downloads a 30m program aaa.zip with the following specific steps:

1. Make a file such as aaa1 with notepad as follows: open ftp.dwonload.com user anonymous [email] zyz@ cenpok.net [/ email] cd / pub/internet/ I get aaa.zip close bye

two。 Dial up and log in to your ISP. Log in to shell with telnet or netterm, which is usually bbs~/ in your home subdirectory

3. Use fttp to upload aaa1 to your subdirectory on the ISP server.

4. Execute nohup fttp-invd aaa2& so that the process is placed in the background of the ISP server, and if you want to know what's going on, you can more aaa2 to know what's going on. At this time you can disconnect or do something else, it is estimated that the time has come (time = 30M/ (33.6K/9) s) to dial up, more aaa2 if it shows that the successful download of aaa.zip means that aaa.zip has been downloaded to the ISP server, you pull back from the ISP server is quite peer-to-peer, remember to del your file (aaa.zip) after the download is completed, so as not to waste ISP resources, it will turn off shell.
