FTP stands for File Transfer Protocol. It is a very simple and useful protocol which allows its users to transfer files between computers.

In this article, we would see how it is used in Linux/Unix systems. ftp program comes along with most Linux distributions. So you don't have to worry about downloading, installing, etc.

Running ftp

Once you have logged in successfully, you may use cd and ls to navigate your directories. They function the same way as Linux command line.

Downloading Files

ftp> get filename

To download multiple files

ftp> mget filename filename filename

You may also use wildcards. For example, acc* would get all files that begin with acc.

ftp> mget acc*

You will be asked before each file is downloaded. You can use the prompt command to get arround this. Uploading Files

Before we can upload, we need to make sure that our local directory is listed correctly. So we will change the directory to the desired directory.

ftp> lcd /home/mysite/

To upload, we use:

ftp> put filename

ftp> mput filename filename filename
ftp> mput acc*
