Programmers must know FTP commands

The format of the file transfer software is FTP <FTP address>. If the connection is successful, the system prompts the user to enter the user name and password:
LOGIN: (enter a valid user name or "ANONMOUS "):
PASSWORD: (enter a valid PASSWORD. If you log on as "ANONMOUS", you generally do not need a PASSWORD ):

Section 1 FTP command Basics

After you enter the FTP site you want to connect to, you can perform file transfer operations. Some important commands and similar commands are as follows:
1) HELP ,? , RHEIP, REMOTEHELP
The HELP command displays the LOCAL command instructions. If not, all available commands are displayed;
? Equivalent to HELP, for example :? CD:
RHELP is the same as HELP, but it is used to display REMOTE Command instructions;
REMOTEHELP is equivalent to RHELP.
2) ASC (ASCll), Bm (BmARY), IMAGE, TYPE
Switch the ASCII transmission mode to the text mode (only the DOC file can be transferred because it is 7-BIT );
Switch the BINARY transmission mode to the BINARY mode (this mode is used except for text files );
IMAGE is equivalent to BINARY:
TYPE allows you to change or display the current transmission mode.
3) BYE and QUIT[Quit]
BYE exit FTP:
QUIT is equivalent to BYE.
4) CD, CDUP, LCD, P ~ WD ,!
CD changes the current working directory, for example, CD \ PUB;[Cwd]
CDUP is returned to the previous directory, which is equivalent to playing CD ..:
LCD allows you to change or display LOCAL working directories, such as LCD \ TMP;
PWD displays the current working directory (REMOTE end ):
! Let you execute shell commands, such :! LS.
5) DELETE, MDELETE, and RENAME
DELETE:
Need MDELETE to delete files in batches? Or ,*
RENAME: Change the REMOTE file name.
6) GET, MGET, PUT, MPUT, RECV, and SEND
GET to download files;
MGET batch downloading files, which must be used with characters, for example, MGET *. GZ;
PUT: upload files;
MPUT: uploads files in batches, which must contain characters;
RECV is equivalent to GET (RECV is short for RECEWE ):
SEND is equivalent to PUT.
7) HASH, PROMPT, VERBOSE, STATUS, BELL
HASH switching # font size. Each font size indicates that 1024/8192 BYTES are transferred:
PROMPT switch iNTERACTIVEON/OFF;
VERBOSE switches the display of all file transfer processes;
STATUS displays the following parameters:
BELL sends a cry when the command is complete.
8) LS, DIR, MLS, MDIR, MKDIR, RMDIR
LS is a bit like the LS (LIST) command in UNIX:
DIR is equivalent to LS-L (LIST-LONG );
MLS only stores objects in a remote directory in a LOCAL file;
MDIR is equivalent to MLS;
MKDIR is like the MD (create sub-directory) in DOS:
RMDIR is the same as RD (delete sub-directory) in DOS.
9) OPEN, CLOSE, DISCONNECT, USER ·
OPEN connection to a remote FTP server;
CLOSE closes the current connection; DISCONNECT is equivalent to CLOSE;
Enter the USER name and password again (a bit like SU in UNIX ).
RETRSTOR
Section 2 FTP commands

The FTP command is one of the most frequently used commands by Intemet users. A large number of FTP Internal commands are encountered no matter how frequently FTP is used in DOS or UNIX operating systems. Familiar with and flexible application of FTP Internal commands can greatly facilitate users and get twice the result with half the effort.
The FTP command line format is:
FTP-v-d-I-n-g [host name], where:
-V -- display all response information of the remote server;
-N. ------ restrict automatic FTP login, that is, do not use ;,
N ----- etRc file:
-D -- use the debugging method:
· G -- cancel the global file name.
The internal commands used by FTP are as follows (brackets indicate optional ):
1) [crud [args) 1: Execute the interactive shell on the local machine, and exit to return to the FTP environment, with the column as follows :! LS *. zip.
