FTP (File Transfer Protocol) Command Examples

The FTP (file transfer program) utility is used to transfer files between a local machine and remote network machine Using the File Transfer protocol. In simple terms it transfers / copies files between two computers. You can transfer files between unix systems and also non-unix systems like windows operating system using FTP.

The FTP command is simple to use and easy to learn. Let see useful examples of FTP command in detail.

FTP Command Examples:

If you are using windows operating system, open the command prompt and practice the below FTP commands. If you are using unix or linux operating systems, just simply type the ftp command on the terminal.

1. Connecting to Remote Host

First you need to connect to a remote host before doing any operations. You can use any one of the following methods to connect to a remote host. First method is

> ftp remote-server-name

connected to remote-server-name

User-Name:

Password:

ftp>

Once the ftp connects to the remote server name, it will prompt you to enter the user name and password. After successful login, your terminal or prompt changes to "ftp>".

Another method is to use the open option with ftp command. This is shown below:

>ftp

ftp>open remote-server-name

connected to remote-server-name

User-Name:

Password:

ftp>

If the ftp command fails to connect to the remote server, then you will get the below error:

ftp: connect: Connection refused

2. Copy file from remote machine to local machine.

The get option is used to download or transfer a file from the remote system to the local system.

ftp> get windows-cleveland.bat

This will download the specified file (windows-cleveland.bat) from the remote systems current directory.

3. Copying multiple files from remote machine to local machine.

You can use the get to transfer multiple files from the remote host to local host.

ftp>get *.png

This will download all the png images to the local machine.

4. Transferring file from local server to remote server

The put option is used to copy the file from the local host to the remote host.

ftp>put linux-virtual-server.rpm

This command puts the rpm file into the remote machine.

5. Transferring multiple files to the remote server.

You can use the put option to transfer more than one file from local system to the remote system.

6. Executing commands in remote machine.

After connecting to the remote network machine using the ftp, you can run commands like ls to list the files, cd to change directory and many more.

ftp> ls

This will list the files and directories in the remote machines current directory.

7. Executing commands in local machine.

Once you have connected to the remote host, to run the commands on local machine you need to exit from the ftp connection. Instead of this, there is a way to run commands on local host without exiting from the ftp connection. Use the ! Symbol before the command you want to run.

ftp> !ls

Now this will list the files in the local machines current directory.
