How To Use Wget Command in Linux


How To Use Wget Command in Linux


GNU Wget is a command-line utility for downloading files from the web. With Wget, you can download files using HTTP, HTTPS, and FTP protocols. Wget provides a number of options allowing you to download multiple files, resume downloads, limit the bandwidth, recursive downloads, download in the background, mirror a website, and much more.

This article shows how to use the wget command through practical examples and detailed explanations of the most common options.

Installing Wget

The wget package is pre-installed on most Linux distributions today.

To check whether the Wget package is installed on your system, open up your console, type wget, and press enter. If you have wget installed, the system will print wget: missing URL. Otherwise, it will print wget command not found.

If wget is not installed, you can easily install it using the package manager of your distro.

Installing Wget on Ubuntu and Debian

$ sudo apt install wget

Installing Wget on CentOS and Fedora

$ sudo yum install wget

Wget Command Syntax

Before going into how to use the wget command, let’s start by reviewing the basic syntax.

The wget utility expressions take the following form:

$ wget [options] [url]
  • options – The Wget options
  • url – URL of the file or directory you want to download or synchronize.

How to Download a File with wget

In its simplest form, when used without any option, wget will download the resource specified in the [url] to the current directory.

In the following example, we are downloading the Linux kernel tar archive:

$ wget

As you can see from the image above, wget starts by resolving the domain’s IP address, then connects to the remote server and starts the transfer.

During the download, wget shows the progress bar alongside the file name, file size, download speed, and the estimated time to complete the download. Once the download is complete, you can find the downloaded file in your current working directory .

To turn off the output, use the -q option.

If the file already exists, wget will add .N (number) at the end of the file name.

Saving the Downloaded File Under Different Name

To save the downloaded file under a different name, pass the -O option followed by the chosen name:

$ wget -O

The command above will save the latest hugo zip file from GitHub as instead of its original name.

Downloading a File to a Specific Directory

By default, wget will save the downloaded file in the current working directory. To save the file to a specific location, use the -P option:

$ wget -P /mnt/iso

The command above tells wget to save the CentOS 7 iso file to the /mnt/iso directory.

Limiting the Download Speed

To limit the download speed, use the --limit-rate option. By default, the speed is measured in bytes/second. Append k for kilobytes, m for megabytes, and g for gigabytes.

The following command will download the Go binary and limit the download speed to 1MB:

$ wget --limit-rate=1m

This option is useful when you don’t want wget to consume all the available bandwidth.

Resuming a Download

You can resume a download using the -c option. This is useful if your connection drops during a download of a large file, and instead of starting the download from scratch, you can continue the previous one.

$ wget -c

If the remote server does not support resuming downloads, wget will start the download from the beginning and overwrite the existing file.

Downloading in Background

To download in the background, use the -b option. In the following example, we are downloading the OpenSuse iso file in the background:

$ wget -b

By default, the output is redirected to wget-log file in the current directory. To watch the status of the download, use the tail command:

$ tail -f wget-log

Changing the Wget User-Agent

Sometimes when downloading a file, the remote server may be set to block the Wget User-Agent. In situations like this, to emulate a different browser, pass the -U option.

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

The command above will emulate Firefox 60 requesting the page from

Downloading Multiple Files

If you want to download multiple files at once, use the -i option followed by the path to a local or external file containing a list of the URLs to be downloaded. Each URL needs to be on a separate line.

The following example shows how to download the Arch Linux, Debian, and Fedora iso files using the URLs specified in the linux-distros.txt file:

$ wget -i linux-distros.txt


If you specify - as a filename, URLs will be read from the standard input.

Downloading via FTP

To download a file from a password-protected FTP server, specify the username and password as shown below:

$ wget --ftp-user=FTP_USERNAME --ftp-password=FTP_PASSWORD

Creating a Mirror of a Website

To create a mirror of a website with wget, use the -m option. This will create a complete local copy of the website by following and downloading all internal links as well as the website resources (JavaScript, CSS, Images).

$ wget -m

If you want to use the downloaded website for local browsing, you will need to pass a few extra arguments to the command above.

$ wget -m -k -p

The -k option will cause wget to convert the links in the downloaded documents to make them suitable for local viewing. The -p option will tell wget to download all necessary files for displaying the HTML page.

Skipping Certificate Check

If you want to download a file over HTTPS from a host that has an invalid SSL certificate, use the --no-check-certificate option:

$ wget --no-check-certificate

Downloading to the Standard Output

In the following example, wget will quietly ( flag -q) download and output the latest WordPress version to stdout ( flag -O -) and pipe it to the tar utility, which will extract the archive to the /var/www directory.

$ wget -q -O - "" | tar -xzf - -C /var/www


With wget, you can download multiple files, resume partial downloads, mirror websites, and combine the Wget options according to your needs.
