The Linux command line provides more flexibility and control than GUI. Many people prefer the command line to GUI because it is easier to use and faster than GUI. Using the command line makes it easier to automate tasks with one line. In addition, it uses fewer resources than GUI.

Downloading files is a daily task, usually performed on a daily basis, including file types such as ZIP,TAR,ISO,PNG. You can use the command line terminal to perform this task easily and quickly. Just use the keyboard. So today, I'll show you how to download files using the command line in Linux. There are usually two known ways to do this, even with the wget and curl tools. For this article, I will use Ubuntu 20.04 LTS to describe the process. But the same command can be run on other Linux distributions, such as Debian,Gentoo and CentOS.

Download files using Curl

Curl can be used to transfer data over a variety of protocols. It uses Curl to support many protocols, including HTTP, HTTPS, FTP, TFTP, TELNET,SCP and so on. You can download any remote file. It also supports pause and resume functions.

First, you need to install curl.

Install curl

Start the command line application in the Ubuntu terminal by pressing Ctrl + Alt + T. Then enter the following command to install curl using sudo.

Linuxmi@linuxmi:~/www.linuxmi.com$ sudo apt install curl

Enter the password when prompted for the password of [sudo] linuxmi.

After the installation is complete, enter the following command to download the file.

Download and save the file using the source file name

To save the file on a remote server with the same name as the original source file, use-O (uppercase O), and then use curl, as follows:

$curl-O [URL]

In addition to-O, you can also specify "- remote-name", as shown below. Both work on the same principle.

Download and save the file under a different name

If you want to download the file and save it to a different name than the file name on the remote server, use-o (lowercase o), as shown below. This is useful when the remote URL does not include a file name in the URL, as shown in the following example.

$curl-o [filename] [URL]

[filename] is the new name of the output file.

Curl-remote-name https://github.com/chrishunt/color-schemes/archive/master.zip curl-o linuxmi https://github.com/chrishunt/color-schemes/archive/master.zip downloads multiple files

To download multiple files, enter the command using the following syntax:

$curl-O [URL1]-O [URL2]

Download files from the FTP server

To download a file from a FTP server, enter the command using the following syntax:

$curl-O ftp://ftp.linuxmi.com/www.linuxmi.com.zip

To download files from a user-authenticated FTP server, use the following syntax:

$curl-u [ftp_user]: [ftp_passwd]-O [ftp_URL]

Pause and resume download

When downloading a file, you can pause it manually using Ctrl + C, or sometimes it will be automatically interrupted and stopped for some reason, and you can restore it. Navigate to the directory where you previously downloaded the file, and enter the command using the following syntax:

$curl-c [options] [URL]

Download files using Wget

Using wget, you can download files and content from Web and FTP servers. Wget is a combination of www and get. It supports protocols such as FTP,SFTP,HTTP and HTTPS. It also supports recursive downloads. This feature is useful if you want to download the entire site for offline viewing or to generate a backup of a static site. In addition, you can use it to retrieve content and files from various Web servers.

Install wget

Start the command line application in the Ubuntu terminal by pressing Ctrl + Alt + T. Then enter the following command to install wget using sudo.

Linuxmi@linuxmi:~/www.linuxmi.com$ sudo apt install wget

When prompted for a password, enter the sudo password.

Download a file or web page using wget

To download a file or web page, open the terminal and enter the command in the following syntax:

$wget [URL]

To save a single web page, enter the command using the following syntax:

$wget [URL]

Download a file with another name

If the name of the download and save file is different from the name of the original remote file, use-O (uppercase O), as shown below. This is useful for you, especially if you download a web page that is automatically saved with the name "index.html".

To download a file with a different name, enter the command using the following syntax:

$wget-O [file name] [URL]

Download files through FTP

To download a file from a FTP server, type the command using the following syntax:

$wget [ftp_link]

To download files from a user-authenticated FTP server, use the following syntax:

$wget-u [ftp_user]: [ftp_passwd]-O [ftp_URL] Recursive download file

You can use the recursive download feature to download everything in a specified directory, whether it's a website or a FTP site. To use the recursive download feature, enter the command using the following syntax:

$wget-r [URL]

Download multiple files

You can download multiple files using wget. Create a text file with a list of files URL, and then download the list using the wget command with the following syntax.

$wget-I [filename.txt]

For example, I have a text file called "linuxmi.txt" with two URL lists to download using wget. You can see the contents of my text file in the following figure.

I will download the file links contained in the text file using the following command:

$wget-I linuxmi.txt

Use the file containing the URL as the download list

You will see that it is downloading two links one by one.

Pause and resume download

You can press Ctrl + C to pause the download. To resume the paused download, change to the directory where you previously downloaded the file and use the-c option after wget, as shown in the following syntax:

$wget-c filename.zip

Using the above command, you will notice that the download has resumed from the paused location.

Summary

In this article, we discussed the basic usage of two command-line methods under Linux, which you can use to download files. One thing to note is that if you do not specify a directory when you download the file, the file will be downloaded to the current directory you are using.
