Simple and practical FTP commands

Simple and practical FTP commands

FTP is one of the earliest protocols used on the TCP/IP network and the INTERNET. It belongs to the application layer of the network protocol group.

The FTP client can send commands to the server to download files, upload files, and create or change directories on the server.

FTP is often used at work. In fact, it is mainly used to upload and download files. The following lists Common commands:

01. ftp 192.168.0.1# Enter the user name and password to log on to the ftp server

A simple Ftp command

A lot!
The FTP command line format is: ftp-v-d-I-n-g [host name], where-v displays all the response information of the remote server; -n indicates that ftp automatic logon is disabled ;. n etrc file;-d: Debug;-g: cancel the global file name.

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

1 .! [Cmd [args]: Execute the interactive shell on the local machine and exit to return to the ftp environment, for example :! Ls *. zip.

2. $ macro-ame [args]: Execute macro to define macro-name.

3. account [password]: Provide the password required to access system resources after logging on to the remote system.

4. append local-file [remote-file]: append the local file to the remote system host. If the remote system file name is not specified, the local file name is used.

5. ascii: Use the ascii type transmission method.

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

7. bin: Binary File Transfer Mode.

8. bye: exit the ftp session.

9. case: when using mget, convert uppercase letters in the remote host file name to lowercase letters.

10. cd remote-dir: Enter the remote host directory.

11. cdup: Enter the parent directory of the remote host directory.

12. chmod mode file-name: Set the file-name access mode of the remote host file to mode, for example, chmod 777 a. out.

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

14. cr: When a file is transmitted using asscii, the carriage return line is converted into a return line.

15. delete remote-file: delete remote host files.

16. debug [debug-value]: sets the debugging mode to display each command order sent to the remote host, for example, deb up 3. If it is set to 0, the debug is canceled.

17. dir [remote-dir] [local-file]: displays the remote host directory and stores the result in local-file.

18. disconnection: Same as close.

19. form format: sets the file transmission mode to format. The default mode is file.

20. get remote-file [local-file]: transfers the remote-file of the remote host to the local-file of the local hard disk.

21. glob: Set the extension of the mdelete, mget, and mput file names, which is the same as the-g parameter in the command line.

22. hash: A hash symbol (#) is displayed for every 1024 bytes transferred (#).

23. help [cmd]: displays the help information of the ftp Internal Command cmd, for example, help get.

24. idle [seconds]: Set the Sleep timer of the remote server to [seconds] seconds.

25. image: sets the binary transmission mode (the same as binary ).

26. LCD [dir]: Switch the local working directory to dir.

27. ls [remote-dir] [local-file]: displays remote-dir in the remote directory and stores local-file in the local file.

28. macdef macro-name: defines a macro. When an empty row under macdef is encountered, the macro defines the end.

29. mdelete [remote-file]: delete remote host files.

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

What are common FTP commands?

The ftp command transfers files between a local machine and a remote machine. The general format of this command is as follows:
C:> ftp host name/ip Address

The most common commands are:
Ls to list the current directory of the remote machine
Cd changes the working directory on a remote machine
LCD changes the working directory on the local machine
Set the file transmission mode to ascii in ascii mode.
Set the file transfer mode to binary.
Close to terminate the current ftp session
Each time the hash data is transmitted in the data buffer, A # number is displayed.
Get (mget) transfers specified files from a remote machine to a Local Machine
Put (mput) transfers the specified file from the local machine to the remote machine
Open connection to remote ftp site
Quit disconnects from the remote machine and exits ftp
