Wget Command in Linux with Examples 2024

Wget Command in Linux with Examples

Learn how to use GNU Wget, a powerful command-line tool for downloading files from the web using HTTP, HTTPS, and FTP protocols. Wget offers numerous features including the ability to download multiple files, resume downloads, limit bandwidth, perform recursive downloads, download in the background, mirror websites, and much more.

In this article, we provide practical examples and detailed explanations of the most common wget options to help you make the most of this versatile utility.

Installing Wget

Most Linux distributions come with the wget package pre-installed nowadays.

To determine if the Wget package is installed on your system, access your console and input “wget” followed by hitting the enter key. If the package is already installed, the system will display “wget: missing URL“. Conversely, if the package is not installed, the system will output “wget command not found“.

In case wget is not present on your system, it can be conveniently installed through your distribution’s package manager.

Installing Wget on Ubuntu and Debian

sudo apt install wget

Installing Wget on CentOS and Fedora

sudo yum install wget

Wget Command Syntax

To begin with, let’s review the fundamental syntax before delving into the usage of the wget command. The format of wget utility expressions is as follows:

wget [options] [url]
  • options – The Wget options
  • url – URL refers to the file or directory that you intend to synchronize or download.

How to Download a File with wget

When utilized without any additional options, wget will download the specified resource from the [url] and save it to the current directory in its most basic form.

In this instance, we’re retrieving the tar archive of the Linux kernel:

wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.17.2.tar.xz

wget download file

The image depicted above illustrates that wget initiates the process by resolving the IP address of the domain. Once the IP address is resolved, it establishes a connection with the remote server and commences the transfer.

While downloading using wget, a progress bar is displayed that shows the file name, file size, download speed, and estimated time left for completion. After the download finishes, the downloaded file can be found in the current working directory.

To disable the output, employ the -q flag. In case the file is already present, wget will append .N (number) to the file name.

Saving the Downloaded File Under a Different Name

If you wish to give a different name to the downloaded file, use the -O option and specify the preferred name afterward.

wget -O latest-hugo.zip https://github.com/gohugoio/hugo/archive/master.zip

The aforementioned instruction will rename the most recent Hugo zip file obtained from GitHub as latest-hugo.zip rather than preserving its original file name.

Limiting the Download Speed

You can use the --limit-rate option to restrict the download speed. The default unit of measurement for speed is bytes/second, but you can indicate kilobytes, megabytes, or gigabytes by appending k, m, or g, respectively. For instance, to download the Go binary and limit the speed to 1MB, execute the following command:

wget --limit-rate=1m https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz

In situations where you prefer to limit the amount of bandwidth consumed by wget, this option can be beneficial.

Resuming a Download

To continue a previously interrupted download of a large file, utilize the -c option to resume the process rather than initiate it anew. This approach proves valuable when your internet connection fails during the file download, as it eliminates the need to restart the download from the beginning.

The ensuing instance pertains to the process of recommencing the download of the Ubuntu 18.04 iso file:

wget -c http://releases.ubuntu.com/18.04/ubuntu-18.04-live-server-amd64.iso

In case the remote server lacks support for download resumption, wget will commence the download anew, thereby replacing any pre-existing file.

Downloading in Background

You can initiate background downloads by adding the -b option. In the instance below, we are executing a download of the OpenSuse iso file in the background:

wget -b https://download.opensuse.org/tumbleweed/iso/openSUSE-Tumbleweed-DVD-x86_64-Current.iso

By default, the output is redirected to the ‘wget-log‘ file in the current directory. To monitor the download’s progress, use the ‘tail‘ command:

tail -f wget-log

Changing the Wget User-Agent

In certain cases, the User-Agent of Wget may be obstructed by the remote server while downloading a file. To overcome this obstacle, you can use the -U option to simulate a different web browser.

wget --user-agent="Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0" http://wget-forbidden.com/

By executing the aforementioned command, Firefox 60 will be simulated to make a request to wget-forbidden.com.

Downloading Multiple Files

To download numerous files simultaneously, specify the -i parameter and then provide the path to a file, either local or external, that contains a list of URLs to be downloaded. It’s important to note that each URL must be listed on a distinct line.

In this illustration, we demonstrate how to obtain the iso files for Arch Linux, Debian, and Fedora by utilizing the URLs listed in the linux-distros.txt file:

wget -i linux-distros.txt


In case you indicate a – as the filename, the standard input will be utilized to read the URLs.

Downloading via FTP

The process for downloading a file from an FTP server that requires a password involves providing your username and password in the following manner:

wget --ftp-user=FTP_USERNAME --ftp-password=FTP_PASSWORD ftp://ftp.example.com/filename.tar.gz

Creating a Mirror of a Website

When using wget, the -m option can be utilized to generate a mirror of a website. This option will enable the creation of a comprehensive local replica of the website, which will involve downloading all internal links as well as the website resources such as JavaScript, CSS, and Images.

wget -m https://example.com

To utilize the downloaded website for offline browsing, it is necessary to provide additional arguments to the aforementioned command.

wget -m -k -p https://example.com

By using the -k option, wget will modify the links present in the downloaded files to enable local viewing. Additionally, with the -p option, wget will retrieve all the essential files required to display the HTML page.

Skipping Certificate Check

To download a file through HTTPS from a host with an invalid SSL certificate, utilize the option “--no-check-certificate“.

wget --no-check-certificate https://domain-with-invalid-ss.com

Downloading to the Standard Output

The given illustration demonstrates how to use wget to download the most recent version of WordPress silently (with the -q flag), direct the output to stdout (with the -O - flag), and then feed it to the tar tool for extraction into the /var/www folder.

wget -q -O - "http://wordpress.org/latest.tar.gz" | tar -xzf - -C /var/www
