Wget Command in Linux with Examples
5 min read
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.
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.
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.
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
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:
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
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 latest-hugo.zip https://github.com/gohugoio/hugo/archive/master.zip
The command above will save the latest hugo zip file from GitHub as
latest-hugo.zip instead of its original name.
Downloading a File to a Specific Directory
wget will save the downloaded file in the current working directory. To save the file to a specific location, use the
wget -P /mnt/iso http://mirrors.mit.edu/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1804.iso
The command above tells
wget to save the CentOS 7 iso file to the
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 https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz
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.
In the following example, we are resuming the download of the Ubuntu 18.04 iso file:
wget -c http://releases.ubuntu.com/18.04/ubuntu-18.04-live-server-amd64.iso
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 https://download.opensuse.org/tumbleweed/iso/openSUSE-Tumbleweed-DVD-x86_64-Current.iso
By default, the output is redirected to
wget-log file in the current directory. To watch the status of the download, use the
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
wget --user-agent="Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0" http://wget-forbidden.com/
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
wget -i linux-distros.txt
http://mirrors.edge.kernel.org/archlinux/iso/2018.06.01/archlinux-2018.06.01-x86_64.iso https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-9.4.0-amd64-netinst.iso https://download.fedoraproject.org/pub/fedora/linux/releases/28/Server/x86_64/iso/Fedora-Server-dvd-x86_64-28-1.1.iso
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 ftp://ftp.example.com/filename.tar.gz
Creating a Mirror of a Website
To create a mirror of a website with
wget, use the
wget -m https://example.com
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 https://example.com
-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
wget --no-check-certificate https://domain-with-invalid-ss.com
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
wget -q -O - "http://wordpress.org/latest.tar.gz" | tar -xzf - -C /var/www
wget, you can download multiple files, resume partial downloads, mirror websites, and combine the Wget options according to your needs.
