This article will explain in detail how ftp uploads data to the server under linux. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

LinuxftpFTP is the standard file transfer protocol of ARPANet, and this network is the predecessor of Internet today. Usually we use the ftp command, mainly to upload and download files, ftp login users are generally virtual users, because this is for security reasons.

Syntax: ftp [- dignv] [host name or IP address]

Parameters:

-v shows the instruction execution process.

-n does not use automatic login.

-g turns off the extension of the local host file name to support special characters.

-I turn off the interactive mode without asking any questions.

-d shows the instruction execution process in detail to facilitate debugging or analysis of program execution.

Example: login 124.16.144.120, command

[root@localhostlane6] $ftp124.16.144.120

Get and mget commands are usually used to download files

A) get

Format: get [remote-file] [local-file]

Transfer files from the remote host to the local host.

To get c:\ a\ 1.jpg on the server, then

Ftp > get/a/1.jpg1.jpg (enter)

B) mget

Format: MGET [remote-files]

Receive a batch of files from the remote host to the local host.

To get all the files under E:\ a\ on the server,

Ftp > cd/a

Ftp > mget*.* (enter)

Enter the prompt command under ftp, but batch acquisition is not prompted one by one.

Note: the files are downloaded to the current directory of the linux host. For example, for ftp commands run under / root/web, the files are downloaded to / root/web.

3. Upload files

A) put

Format: putlocal-file [remote-file]

Transfer a local file to the remote host.

If you want to transfer the local 1.jpg to the remote host c:\ an and rename it to 2.gif

Ftp > put1.jpg/a/2.gif (enter)

B) mput

Format: mputlocal-files

Transfer a batch of files from the local host to the remote host.

To upload all bmp files under the local current directory to the server c:\ a

Ftp > cd/a (enter)

Ftp > mput*.jpg (enter)

Note: all the uploaded files come from the current directory of the host. For example, for a ftp command run under / root/web, only the file linux under / root/web will be uploaded to the server c:\ a.
