Linux FTP command

What is the difference between anftp get command and a mget command ?

get Download only one file at a time, mget can download more than one file at a time, and support wildcard characters, it is necessary to note that in mget, you need to choose y/n for each file, if you want not to interactively download all the files, you can first use the prompt command Turn off interactive mode (off: Prompt off; open: Prompt On).

Ii. what command doesFTP use to locate the path of the server and local hard disk?

In FTP , switch the local path with the LCD and switch the path of the remote server with the CD. The commands that are commonly used are as follows:

CD directory name (enter server directory) LCD directory name (enter the local directory)

CD \ (back to the server root) LCD \ (back to the local root directory)

Cd.. (Back to previous level) LCD. (Back to previous level)

Three! What is the purpose of the order ?

Executes local shell commands , such as:!dir (show native when pro directory content), if not added! For example: Dir (displays the current directory contents of the server)

Does theFTP command support a folder/file name that contains spaces?

Support, as long as the reference with double quotation marks "" Can!

Five, the following is the command -line method of using FTP Practical Practice

Suppose you have an FTP server:ftp. test.com, User name: username, password: user1234. Create a folder "Qint" on the local computer D: disk. Copy the file you want to upload to D:\qint. To upload files locally from the FTP command , download the following steps from the server:

1, "start" → "Run" → enter "FTP"

2, open ftp. test.com

Note: This step can be combined with the first step to enter directly in "Run":FTP ftp. test.com. If your FTP server is not using the 21 default port, if the port is 2121, then this step of the command should be in the following space plus 2121, that is, "open FTP. test.com

3, username
Note: You are prompted to enter a user name

4, user1234
Note: Prompts you to enter the password, the password does not echo, after playing the password to return. If your password is entered incorrectly, you will not be prompted to re-enter, then you will type "user" command , the third step appears, you can re-enter the user name and password.

5. Dir
Note: After you have successfully logged in, you can view the files and directories in the FTP server with the dir View command , and you can only view the files with the LS command .

6, mkdir Qint
Note: The Qint directory is established under the root directory on the FTP server

7. CD Qint
Note: Enter the directory Qint, with "CD your directory name" can go to the current directory of the next level of directory, this is the same as DOS.

8. Bin

Note: Binary transfer is in use. If you want to upload the download, this step is very important, do not first execute this command , upload download will be very slow. Most systems, including UNIX systems, have only two modes: text mode and binary mode. Text transmitters use ASCII characters and are separated by return and newline characters, binary mode is faster than text mode, and all ASCII values can be transferred, so system administrators typically set FTP to binary mode instead of converting or formatting. Generally speaking, we'd better use binary mode, so that we can ensure that there is no error.

9, LCD D:\qint

Note: Locate the local default folder, which was previously created in the D: disk

10,!dir

Note: View files and directories in the local folder

11. Put I001.jpg
Note: Upload the file i001.jpg in the current directory (D:\qint) to the FTP Server default directory. You can upload all files to the FTP server with "Mput * *".

12.Get d123.jpg
Note: Download the file d123.jpg in the FTP Server default directory to the current directory (D:\qint). You can download all files to d:\qint with "Mget * *"

13. Delete * *

Note: Delete all the files in the server's corresponding directory qint.

14. cd.

Note: Go back to the top level directory, which is the root directory. Go back to the previous directory with "CD.." Be aware that there are spaces in the middle. Return the root directory with "CD \".

15, Mrdir Qint

Note: Delete the directory qint. Delete the directory, you cannot have files and directories in this directory, or it will not be deleted.

16, bye

Note: Exit the FTP server.

When uploading the download, pay special attention to the server and the local computer's current directory, the file is from where to where the problem. To view the FTP server's current directory command for PWD, you can use the CD command to locate the server's directory. You can use the LCD command to locate the local computer's directory.

The above example applies to the most commonly used commands for uploading and downloading using the FTP command line, you can also use the command "? "To see more commands .

ftp commands are one of the most frequently used commands for Internet users, whether using ftp under a DOS or Unix operating system, Will encounter a large number of FTP internal commands . The familiar and flexible application of FTP internal commands , can greatly facilitate users, and receive a multiplier effect. the command line format for FTP is:ftp -v-d-i-n-G [hostname], where -V Displays all the response information for the remote server; - N Limit ftp automatic login, that is, do not use; . n etrc file; - D use debug mode; -G cancels the global file name. the internal commands used by FTP are as follows (brackets indicate options): 1.!
