text: What Is the Wget Command and How to Use It (12 Examples Included)
  This guide teaches you how to use wget command on Linux. It gives 12 examples of wget commands in action to help you use them. Once you’re done, you’ll know all about wget and how to use it to get files from the web.
  What Is the Wget Command?
  Wget is a command-line tool that makes it possible to download files from the internet directly to your active directory. It operates in the background, allowing tasks to continue even if you’re offline. The name is a combination of World Wide Web and the word get. It supports downloads via FTP, SFTP, HTTP, and HTTPS.
  Wget is created in portable C and usable on any Unix system. It’s also possible to implement on Mac OS X, Microsoft Windows, AmigaOS, and other popular platforms.
  How to Install Wget?
  For this wget command demonstration, we’ll be using Ubuntu 22.04. But the syntax will work on any other Linux distribution too.
  Firstly, access your server via SSH:
  ssh user@your_server_ip -port
  To install wget on Ubuntu 22.04, execute the following command:
  sudo apt-get install wget
  To install wget on CentOS 9 Sream or it’s previous distros, use:
  sudo yum install wget
  Once the setup finishes, you’ll be ready to use it. Also, the knowledge of basic SSH commands can make things easier.
  Wget Command Examples
  To get you started, we’ll provide 12 wget command examples that you can use for everyday tasks. Keep in mind that you may also call this function from scripts and cron jobs!
  Using Wget Command to Download Single Files
  One of the most basic wget command examples is downloading a single file and storing it on your current working directory. For example, you may get the latest version of WordPress by using the following:
  Here is the output that you will see:
  --2018-02-23 12:53:10-- https://wordpress.org/latest.zip Resolving wordpress.org (wordpress.org)... 184.108.40.206 Connecting to wordpress.org (wordpress.org)|220.127.116.11|:443... connected. HTTP request sent, awaiting response... 200 OK Length: 9332728 (8,9M) [application/zip] Saving to: 'latest.zip' latest.zip 100%[===================>] 8,90M 6,88MB/s in 1,3s 2018-02-23 12:53:14 (6,88 MB/s) - 'latest.zip' saved [9332728/9332728]
  In this example, a file named latest.zip will be downloaded in the current working directory. You’ll also see extra information, such the download progress, speed, size, time, and date.
  Using Wget Command to Download Multiple Files
  We can take wget usage one step further and download multiple files at once. To do that, we will need to create a text document and place the download URLs there. In this example, we will retrieve the latest versions of WordPress, Joomla, and Drupal by using wget. Enter the following:
  This will create an example.txt file and open a text editor interface. Paste these links there:
  https://wordpress.org/latest.zip https://downloads.joomla.org/cms/joomla3/3-8-5/Joomla_3-8-5-Stable-Full_Package.zip https://ftp.drupal.org/files/projects/drupal-8.4.5.zip
  Once done, you may use -i to get all the files stored in your example text file:
  wget -i example.txt
  Wait for the process to finish and you’ll have the installations of three most popular content management systems.
  Using Wget Command to Get Files Under Different Names
  In this wget example, we will save a file using a different name with the help of -O option:
  wget -O wordpress-install.zip https://wordpress.org/latest.zip
  In this case, the downloaded resource will be saved as wordpress-install.zip instead of it’s original name.
  The -O option makes unzipping archives in Linux more efficient, as you don’t need to retype the full name.
  Using Wget Command to Save Files in Specified Directory
  You can utilize wget to place a file in another directory using -P function:
  wget -P documents/archives/ https://wordpress.org/latest.zip
  The file you retrieve using this syntax will appear in documents/archives/ folder.
  Using Wget Command to Limit Download Speed
  With wget, you can also limit the download speed. This is useful when retrieving huge files and will prevent it from using all of your bandwidth. This wget example will set the limit to 500k:
  wget --limit-rate=500k https://wordpress.org/latest.zip
  Using Wget Command to Set Retry Attempts
  Internet connection problems can cause your download to interrupt. To tackle this issue, we can increase the retry attempts using -tries function:
  wget -tries=100 https://wordpress.org/latest.zip
  Using Wget Command to Download in Background
  For extremely large files, you may take advantage of -b function. It will download your content in the background.
  wget -b http://example.com/beefy-file.tar.gz
  A wget-log will appear in your working directory, which can be used to check your download progress and status. You can also use the tail command:
  tail -f wget-log
  Using Wget Command to Download via FTP
  The command is also usable with FTP. You’ll only need to specify the username and password as in this wget example:
  wget --ftp-user=YOUR_USERNAME --ftp-password=YOUR_PASSWORD ftp://example.com/something.tar
  Using Wget Command to Continue Interrupted Downloads
  Your download can get interrupted if you lose the internet connection or experience a power outage. This is quite a common occurrence when getting huge files. Instead of starting over, it’s possible to continue the download using -c function:
  wget -c https://example/very-big-file.zip
  If you proceed without the -c function, the new file will have .1 added at the end as it already exists.
  Using Wget Command to Retrieve Whole Websites
  It is also possible to use wget command to download the content of an entire site. This will let you view it locally without an internet connection. Here is an example:
  wget --mirror --convert-links --page-requisites --no-parent -P documents/websites/ https://some-website.com
  Let’s analyze the ingredients of this wget command:
  –mirror | It makes your download recursive. |
  –convert-links | All links will be converted for proper offline usage. |
  –page-requisites | The following will include all necessary files such as CSS, JS, and images. |
  –no-parent | It ensures that directories above the hierarchy are not retrieved. |
  -P documents/websites/ | This ensures that all content goes to our specified directory. |
  Once the process finishes, you’ll be able to open the downloaded website locally and find all the files in documents/websites/ folder.
  Using Wget Command to Locate Broken Links
  Let’s try something more advanced. We can use the wget command to locate all broken URLs that display 404 error on a specific website. Start by executing the following:
  wget -o wget-log -r -l 5 --spider http://example.com
  -o | Gathers output into a file for later use. |
  -l | Specifies the recursion level. |
  -r | Makes the download recursive. |
  –spider | Sets wget to spider mode. |
  We may now investigate the wget-log file to find the list of broken links. Here’s the command to do it:
  grep -B 2 '404' wget-log | grep "http" | cut -d " " -f 4 | sort -u
  Using Wget Command to Download Numbered Files
  If you have files or images numbered in a certain list, you may easily download all of them with the following syntax:
  Congratulations! By completing this tutorial you have learned various uses for the wget command. You can now utilize it to get single or multiple files. In addition, you’ve learned some advanced uses, such as downloading a whole website or locating broken URLs. For more information, you may also check the official documentation.
