Cómo usar FTP desde la linea de comandos

How do I use FTP from a command line?

Updated: 05/05/2017 by Computer Hope

Note: FTP is not an encrypted transmission, which means any data sent over it, including your username and password, could be read by anyone who may intercept your transmission. If you're wanting a more secure transmission, we suggest using SFTP.

• Connect using FTP
• Send and receive a file in FTP
• FTP commands

Connect using FTP

To connect to another computer using FTP at the MS-DOS prompt, command line, or Linux shell type FTP and press Enter. Once in FTP, use the open command to connect to the FTP server, as shown in the example below.

open ftp.example.com

In the above example, you'd substitute example.com for the domain name or IP address of where you are connecting. An example would be open 192.168.1.12.

Note: By default, the open command uses the TCP port 21 to make the FTP connection. If a different TCP port is needed for connecting to the domain name or IP address you are using, enter the port number after the domain name or IP address in the open command.

Once connected, a username and password prompt will appear. Once these credentials have been entered, the server allows you to browse, send, or receive files, depending on your rights. Some servers may also allow anonymous logins using guest or an e-mail address.

Send and receive a file in FTP

To get files from the server onto your computer, use the get command as shown in the example below. In this example, you would get the file myfile.htm.

get myfile.htm

Tip: If you want to get more than one file, use mget and wildcards. For example, if you wanted to get all files that end with .htm, you could type mget *.htm. Finally, if you do not want to be prompted as each file is being sent, make sure to type prompt to disable prompting.

To send a file from your computer to the computer you are connected to, assuming you have the rights, use the send command as shown in the example below. In this example, we are sending the myfile.htm to the current directory.

send myfile.htm

It is important to realize that the files being sent must be in your local working directory, which is the directory you were in when you typed the FTP command. If you want to change to the directory that contains your files, use the lcd command. For example, in Windows, you'd type lcd c:\windows to set the local directory to the Windows directory.

FTP Commands

Depending upon the version of FTP and the operating system being used, each of the below commands may or may not work. Typing -help or a ? will list the commands available to you. Below is a general description of FTP commands available in the Windows command line FTP command.
