The FTP protocol is one of the most common network protocols used by Internet users. The vast majority of people use various FTP clients to download something from FTP servers. But not many people know that Windows has the ability to connect to FTP servers from command line.
This tip will show you how download files from FTP servers using simple DOS commands.
In order to download file from ftp from windows command line Let's do a few simple steps:
Perhaps many will say that it is much more convenient to download files using multifunctional download managers or ftp clients. But if necessary (or alternatively), you can use simple DOS commands that will allow you download files from ftp at no additional cost.
FTP (File Transfer Protocol) is the most popular protocol for transferring files (download and upload) from one system to another system. This provides a fast way to transfer files. There are many Linux and Windows applications available such as VSFTPD, ProFTPD for Linux, FileZilla Server for windows and macOS.
There are various ways to connect to an FTP server using graphic environment, but the system administrator must know the power of the command line. And in this topic "Download and upload files via FTP using the console" I will tell you how you can work with the command line to transfer / receive data.
1. Connecting to an FTP server using the command line
The terminal is used to connect to any server using the command line.
$ ftp ftp.site
2. Upload file to FTP server
FTP put is used to upload a file to the server. First, you need to navigate to the desired folder on the FTP server to upload the file and use the following command.
ftp> cd uploads ftp> put /home/captain/my_file.txt
3. Download one file from FTP server
To download a file from an FTP server, we use the get command. Using this command we can upload one file. To download any file from an FTP server, first login to the FTP server, then navigate to the directory and use the following command to download any file:
Ftp> get my_file.txt
4. Upload multiple files to an FTP server
To upload multiple files to an FTP server we use the MPUT command. We can specify a wildcard character to upload multiple files to the server at the same time. First, navigate to the desired folder on the FTP server to upload the file and use the following command. It will upload all files with .txt extension to /home/captain directory for uploaded files on FTP server.
ftp> cd uploads ftp> lcd /home/captain/ ftp> put *.txt
5. Download multiple files from FTP server
To download multiple files from an FTP server, we use the MGET command. Using this command you can upload files.
ftp> mget *.txt

-v- Disabling the display of responses from a remote server.
-n- Disable automatic login on initial connection.
-I- Disable interactive prompts when transferring multiple files.
-d- Enable debug mode.
-g- Disable globalization of filenames (see GLOB command).
-s:filename- Specify a text file containing FTP commands that will be executed automatically when FTP is started.

As can be seen from the list of listed commands, the standard FTP client in operating systems Windows supports a far from complete list of standard ftp commands and, what is most annoying, it does not support the command to switch to passive mode ( passv) exchange with the FTP server, which makes it unsuitable for communication with FTP servers, the connection to which is performed using network address translation technology NAT. In other words, a standard FTP client is not suitable for exchanging files with servers external to the client's subnet. This applies to everyone Windows versions, including Windows 10. It is this fact that determines the scope of the ftp.exe utility - only in local networks where a direct TCP connection between client and server is possible.
Client session example FTP Windows:
open 192.168.1.1- open connection to server 192.168.1.1
user admin- use username admin when connecting to the server. In response to this command, the server will request a password.
adminpass- entering a password for the user admin
ls- display a list of files and folders in a remote directory
get myfile.txt- accept file myfile.txt from the remote directory to the current local directory.
lcd C:\files- change the current local directory.
get myfile.txt- accept file myfile.txt from the remote directory to the current local directory (C:\files) .
When using the Windows FTP client in batch files, it is often used to run the program in the mode of managing FTP commands written to a text file.
ftp -s:ftpcomm.txt- A list of commands is written to the ftpcomm.txt file, in the same order in which they would be entered in interactive mode. For example, to receive the binfile.bin file in the C:\temp directory.

SYNTAX
Ftp [-v] [-d] [-i] [-n] [-U] [-p] [-g]
DESCRIPTION
The ftp program allows you to transfer files to or receive files from a remote computer, and works with files and directories on a remote computer.
WORK WITH FTP.
To use the ftp program, you need to open a link between your machine and the remote machine where or from where you want to move the file. This program allows you to have multiple links at the same time, although you can issue commands that only affect one link. Multi-machine communication allows you to communicate with multiple machines in a single ftp session. You do not need to re-register on another machine when you want to change the machine for communication. The link used in this moment, is called the current link.
Types of file recording for transfer to ftp.
The ftp program allows you to use two types of notation: ASCII or binary. Use ASCII for text files. Binary is used for binary data, which must be a continuous sequence of bits. ASCII is the default. The binary view can be used for some special files, such as programs, pictures, archives.
ftp call.
To invoke ftp from a UNIX shell, enter the ftp command. When the command is executed, a prompt for that command will appear on your screen. It looks like this:
Ftp> You can specify the name of the machine you want to contact, although this is not required. The following example shows how the machine name ftp.botik.ru is written: $ ftp ftp.botik.ru This is equivalent to using the ftp open command to establish a connection with the machine you named. You can also call ftp without a host name, for example: $ ftp If you didn't set a host name when you called ftp, you must open a link to that host in ftp. This is done using the ftp open command before you start transferring files. For more information on this subject, see the "Description of ftp Commands" section later in this chapter.
ftp options.
Additionally, when calling ftp, you can specify some options for this command. These options are placed after the name of the ftp command, but before the host name, if any. Each option consists of a dash (-) and one letter, for example: -v. Each option has a corresponding command of the same name that can be used inside ftp. You should distinguish between the use of options and the corresponding ftp commands.
| -v | Makes ftp run in verbose mode. In this mode, ftp messages sent by a remote machine to ftp appear on your display screen. In addition, if you use this mode, after each file transfer is completed, a statistical message about it appears. This mode is set by default if ftp is running interactively. If ftp is running in command mode, verbose mode is disabled, then the -v option turns it on. You can enable this mode inside ftp with the verbose command. |
|---|---|
| -d | Makes ftp run in debug mode. In this mode, ftp messages sent by ftp to a remote machine are displayed on your display screen. If you do not use this option, no information is displayed. You can also invoke this mode in ftp using the debug command. |
| -n | Prevents using ftp auto-registration, during communication with a remote machine. When autologin mode is set, ftp will automatically identify you to the remote machine and log you in to that machine. (See "Using the .netrc file for automatic registration" later in this section.) If you use the -n option to disable automatic registration, you will need to use the user command to manually log in to the remote machine. |
| -g | Causes UNIX filenames to be stripped of their extensions, such as the wildcard (*). If you do not use this option, ftp expands filenames with a generic extension in the file list. You can use the glob command instead of this option. |
Using the .netrc file for automatic registration.
You can create a file named .netrc in your home directory as an added convenience. This file contains registration data element strings for each machine you need for automatic communication. When you call ftp specifying a host, that is, when you open a connection to a host at the same time as calling it, ftp reads the .netrc file. If there is a member string for this machine, then ftp will automatically connect your machine to that remote machine. If you have opened the link in verbose mode, you will see how this happens. The file format consists of individual fields, represented by key fields:
Machine name login name password password where machine, login, password are keywords, followed by the character data required for registration:
| machine | Node name. |
|---|---|
| login | User name for registration. |
| password | The password of the user on this node. The password is written in normal unencrypted text form. If you have included your password in the .netrc file, then you must disable this file for your group and all other users to prevent your password from being revealed. Otherwise, ftp will not allow you to use this file. For additional information see the documentation for the chmod command for file permissions. There is some risk in writing your password to a file. You must weigh all security conditions. Ask your administrator about all the features before using this file. |
Limit for ftp commands.
There are several advanced commands that provide additional convenience to the user. But not all ftp servers understand them. The commands whose use will be described later in this chapter have certain limitations. The ftp program can provide a list of supported commands. To obtain such information, you need to use the command after establishing a connection with the remote machine.
Description of ftp commands.
When the ftp prompt appears on the screen, you can enter one of the commands described later in this section. After executing the command, the ftp prompt will appear again. Depending on which mode is set: verbose or debug, additional messages may appear. After each command, press Enter. The command will not start until you press Enter. If you make a mistake while typing a command, you can use the BACKSPACE key to edit the text.
You do not need to enter the command name in full, you can enter a certain number of characters, sufficient for identification. In most cases, this is one or two characters from the name of the ftp command. However, it is better not to be lazy and to type commands completely. The fact is that the ftp client on the joker server can be changed system administrator. Not all clients understand short commands. For example, before they could be used. But one fine day, the ftp program was replaced. They put a more advanced version. I don’t know how advanced she is, but she doesn’t understand short commands.
| ! | This command suspends ftp and invokes the command language (shell) on the local machine. Any character(s) after the exclamation point are treated and executed as shell commands. You can then return to ftp by exiting the shell. All ftp options and associated remote machines are returned to the same state they were in before this command was issued. If a shell command is printed on the same line as !, then only that command is executed. After executing the command, the ftp program returns to command mode. |
|---|---|
| append | The append command causes ftp to append the contents of the local file to the end of the file on the remote machine you are currently connected to. When you call this command, you can specify which file to append to which, for example: ftp> append local_file_name file_name of remote_machine You can also use just the command name and then be prompted for filenames, for example: ftp> append (local-file) local_file_name ( remote-file) file_name of the remote_machine |
| ascii | This command tells ftp to convert files to ASCII code. By default, the code is always ASCII. |
| bell | This command causes a signal to appear on your terminal after each file transfer is completed. To stop beeping, you need to type this ftp command again. |
| binary | This command causes ftp to transfer the file in binary. |
| quit | This command exits ftp. This command closes all open links. |
| cd | This command replaces the directory name on the remote machine with a new one. You can write a new name when you call the command, as shown in the example: ftp> cd /usr/bin You can only use the name of the ftp command, then the machine will ask for a new directory name, for example: ftp> cd (remote-directory) /usr/ bin |
| close | This command closes the current connection. However, there is no exit from ftp. You can create another connection. |
| debug | This command turns debug mode on and off. If the mode is turned on, then a message appears on your display about this, there are no messages when you turn it off. |
| verbose | This command turns the verbose mode on and off. If the mode is turned on, then a message appears on your display about this, there are no messages when you turn it off. |
| delete | This command deletes a file on the remote machine you are currently connected to. You can specify the name of the file to be deleted when calling the ftp command: ftp> delete filename to delete If you prefer, you can leave out the name when calling the ftp command. Then the machine will ask you for a name, for example: ftp> delete (remote-file) the name of the file to delete |
| dir | This command will give you the table of contents of the directory on the remote machine you are connected to. You can specify the name of the directory to be printed when invoking the ftp command. For example: ftp> dir /usr/bin If you don't specify a directory name, the current directory on the remote machine will be printed. You can also have ftp write the results of a command to a file before it appears on the screen. This is done as follows: ftp> dir /usr/bin printfile You must specify the directory name before the name of the output file (here printfile). Thus, if you want to print the current directory to a file called printfile, do this: ftp> dir . printfile where "." means the current directory. |
| get | This command copies a file from the remote machine you are currently connected to. This file is copied to your directory on the server. Use the mget command to copy multiple files at once. When you call this command, you can specify the name of the file on the remote machine and the name in your directory where you will copy the file. For example: ftp> get remote_machine_filename your_machine_file_name If you just specify the filename of the remote machine you want to copy, the file on your machine will have the same name. Example: ftp> get remote_machinename You can only write the ftp get command. Then the ftp program will ask you for a filename, for example: ftp> get (remote-file) filename of the remote machine (local-file) filename of your machine |
| glob | This command causes ftp to disallow UNIX filename extensions, such as the generic "*". This command serves to both disable and enable the extension, so that if given again, the extension will be enabled again. After allowing the extension, ftp will append the extension to all filenames when listing files. |
| hash | This command causes ftp to display a "#" character on the screen after each block of data that is sent by the remote machine. The size of the data blocks may vary depending on the version. software. Today on the joker machine it is 1024 bytes. After entering this command, the current data block size will be printed. This command turns on and off the output of the "#" character on the screen when it is redialled. Thus, you will be able to evaluate the file transfer speed. |
| help | This command displays information about ftp activity. If you specify a command name after help, then information about this command will appear. Simply typing help will bring up a list of ftp commands. |
| lcd | This command changes the working directory used by ftp on your machine. You can specify the name of the directory you want as a working directory, for example: ftp> lcd /home/student/your_dir_name If you don't specify a directory name, the current directory will be used. |
| ls | This command prints an abbreviated listing of the directory contents of the remote machine you are currently connected to. You can specify the name of the directory you want to print. For example: ftp> ls /usr/bin If you don't specify a name, the current directory will be printed. You can specify that the results of the command execution be placed in a file before they appear on the display. This is done by specifying the name of a file on your machine where the directory listing should be placed, for example: ftp> ls /usr/bin printfile The directory name must be set before the file is printed (here printfile). For example, if you want to print the current directory to a file named printfile: ftp> ls . printfile where "." put to emphasize that the directory is current. |
| mdelete | This command deletes the list of files on the remote machine you are currently connected to. You can specify filenames to delete when calling the command. For example: ftp> mdelete remote_machine_file_name 1file_name... Otherwise, you can just use the command name. The ftp program will prompt you for the name(s): ftp> mdelete (remote-files) filename1filename2... |
| mdir | This command lists the directory listing of the remote machine and puts the result in a file in your directory. You can specify a list of files on the remote machine and a filename on your machine where to place the result when the command is invoked. For example: ftp> mdir filename of remote_machine... printfile Note that the last name is the name of a file in your directory. It's possible to just use the command name. The ftp program will then prompt you for the file name, for example: ftp> mdir (remote-files) remote_machine_file_name... printfile local-file printfile? y |
| mget | This command copies several files from the remote machine you are currently connected to into your directory. Files after copying will have the same names as on the remote machine. You can specify a list of files to be copied: ftp> mget remote_machine_file1_name file_2name... If you didn't specify filenames when invoking the command, ftp will prompt you for them: ftp> mget (remote-files) remote_machine_file1_name file_2name... |
| mkdir | This command creates a directory on the remote machine you are currently connecting to. You can specify a directory name when invoking the command, for example: ftp> mkdir /u/mydir If you don't specify a directory name, ftp will prompt you for it, for example: ftp> mkdir (directory-name) directory_name Of course, to run this command, you must have write permission on the remote machine. |
| mls | This command takes an abbreviated list of the group of files in the current directory on the remote machine and places the result in a file on your machine. You can specify a list of files on the remote machine and a file on your machine where to place the result when calling the command, for example: ftp> mls file_name of the remote_machine... printfile remote-files) file_name of remote_machine... printfile local-file printfile? y |
| mput | This command copies one or more files from your directory to the remote machine you are currently connected to. On the remote machine, the files will have the same names. Of course, you must have write permission on the remote machine to run this command. You can specify a list of files when you call the command, for example: ftp> mput 1 file_of_your_dir 2 file_of_your_machine... If you don't specify names, ftp will ask you about it: ftp> mput (local-files) file_1_name of_your_dir file_2_name... |
| nmap | Use this command to set and unset the file name resolution mechanism. This command is useful when communicating with UNIX-incompatible machines that use a different way of naming files. For example, servers based on Apple Macintosh. Renaming local machine files is done with get and mget commands, and the remote machine with the put and mput commands. |
| ntrans | Use this command to enable or disable the filename character translation mechanism. This command is useful when connecting to a UNIX-incompatible remote machine that uses a different file naming convention. For example, servers based on Apple Macintosh. Translation of filenames on the local machine is done with the get and mget commands, and on the remote machine with the put and mput commands. |
| open | This command establishes a connection with a remote machine that is supposed to transfer files. When calling the command, you can specify the machine name, for example: ftp> open ftp.botik.ru If the name is not specified, the program will ask for it: ftp> open (to) machine name port on the remote machine. If a port is specified, then ftp will open communication on that port if it is preferred over the default. Port changes are made if you are asked about it or it is set by the system administrator. If the port is not set, then the program does not request it. |
| prompt | This command prevents you from asking ftp for permission to move between files in multi-file commands such as mget. This command is enabled and disabled when redialling. |
| put | This command moves a file from your machine to the remote machine you are currently connected to. To transfer multiple files at the same time, use the mput command. You can specify the filename of your machine and the filename of the remote machine when you call the ftp command, for example: ftp> put yourfilename remote_machine_filename or ftp> put yourfilename Of course, you must have write permission on the remote machine to run this command. If you do not specify the name of the file(s), then the program will prompt you for them, for example: ftp> put (local-file) your_file_name (remote-file) file_name of the remote_machine If you do not specify the file name of the remote machine, then the put command will create a file on the remote machine with the same name as your machine. |
| pwd | This command prints the name of the current working directory on the remote machine you are currently connected to. |
| bye | The command is similar to the quit command mentioned above. |
| quote | The command causes ftp to send the parameters you enter into the machine to the remote machine for execution. Options are ftp commands and other options. The commands that ftp supports can be displayed on the screen using the remotehelp command. You can enter this command when invoking the ftp program, for example: ftp> quote NLST If you specify only the command name, ftp will ask you for the command line to use, for example: ftp> quote (command-line to send) NLST This command follows use only on the advice of your system administrator. |
| recv | This command is the same as the get command above. |
| remotehelp | This command requests ftp help on the remote machine you are currently connected to. This information tells you what commands the remote machine supports. |
| rename | This command renames a file on the remote machine you are currently connected to. When calling the command, you can use filenames, for example: ftp> rename old_file_name new_file_name If you used only the command name, then ftp will ask for file names: ftp> rename (from-name) old_file_name (to-name) new_file_name Of course, to execute this command you must have write permission on the remote machine. |
| rmdir | This command deletes a directory on the remote machine you are currently connected to. You can specify the name of the directory to be deleted when the command is invoked, for example: ftp> rmdir /u/mydir or you can leave out the name when the command is invoked and the machine will prompt you for it: ftp> rmdir (directory-name) /u /mydir This command is not always supported by the remote machine. Of course, you must have write permission on the remote machine to run it. |
| send | This command is similar to the put command above. |
| sendport | This command causes ftp to disable the ability to set the local machine port for remote machine data. This command can be enabled and disabled by typing it again. When calling ftp, a specific port is set by default. This command should be used on the advice of your system administrator. As a rule, it is needed only when working with some "wrong" ftp server, which is incompatible with your client program. |
| status | This command causes ftp to display its current status on your terminal. The status includes the modes that are selected by the bell, hash, glob, port, type commands. |
| type | This command sets the format in which the file is transferred. ASCII and binary codes are allowed. This command is similar to the ascii and binary commands. If you didn't specify a type when calling the command, then ASCII is set. |
| user | This command allows you to identify yourself on the remote machine when establishing a connection. This auto-registration is enabled with the -n option when calling ftp. In this case, this command is not needed. If automatic registration is disabled, then use this command to register and authenticate yourself on the remote machine. The remote machine needs to be told three kinds of information about who you are: login, password, and resource name. The username is required for all machines, the password and share name are required only for some systems. You can enter all of this information when invoking the user command, for example: ftp> user mike cat myaccount You can leave out all of this information when invoking the command. Then the program will ask you about it, for example: ftp> user (usename) mike(username) password: Account: myaccount(sharename) Note that your password is not displayed when you type it to protect your information. If you have not typed a password or resource name, then you will not be prompted for them. |
| verbose | This command causes ftp to disable verbose mode. This command is turned on and off when redialling. In verbose ftp mode, protocol messages sent by a remote machine appear on your terminal. In addition, this mode displays statistics after each file is transferred. If this mode is disabled, then this information is not displayed. |
| ? | Another name for the help command. |
FTP examples.
This section illustrates how ftp can be used. Below are three examples. These examples use two machines, a local machine named HERE and a remote machine named THERE.
Description of 1 example.
This example shows the use of ftp to send and receive files. The ftp command is called with the name of the host machine and the user is automatically logged on to another machine, because. the -n option is not used.
Verbose mode is disabled using the verbose command. The user then changes the working directory on the remote machine to the /etc directory. Because there is no -d option and there is a verbose command, verbose mode is disabled and no messages other than the ftp prompt appear.
The user, using the ls command, obtains an abbreviated listing of the /etc directory on THERE. the ftp command outputs three files in the /etc directory. The get passwd command then copies the passwd file from THERE to HERE. A file called passwd is created on machine HERE if a machine name was specified.
The put command is used to copy a file called wall from the current working directory of the local machine (HERE) to the /etc directory of the remote machine (THERE). This file is copied with the same name because its own name was not specified. After the transfer is complete, the /etc listing appears, which already has four files, including wall, which was just copied from the HERE machine.
The bye command is then used to return to the operating system shell on the local machine HERE.

This example illustrates the screen images that can be obtained using several ftp options. After calling ftp with the name of the remote host, the user invokes a command that will return the debug mode. The ftp command then prints messages to the screen indicating that the option is enabled. The user then changes the working directory on the remote machine to /etc. Because there are debugging and verbose modes, messages about sending commands to the remote machine (--> CWD / etc) and responses received from the remote machine (250 CWD command successful) will appear on the screen. Note that the cd command, which has the same form as the UNIX change directory command, is sent as a CDW command (change working directory on a remote machine). This command is used by ftp instead of cd so that it works independently of the system command.
Following the cd command, the user puts the pwd command to confirm the change to the working directory. The ftp commands will display on your screen the messages sent between your (local) and remote machine, and then the current working directory on the remote machine will appear. The user then types in the hash option, which prompts a message that the option is allowed. The get wall myfile command tells ftp to retrieve the wall file and place it in the file myfile in the current working directory on your machine. The ftp command will print messages sent between the local and remote machines about the start of a transfer and then print a hash label for each block of information received. After the transfer is completed, the screen displays statistics showing the time it took to transfer and the date the file was transferred. After receiving the file, the user closes the connection with the close command and exits ftp with the bye command.
