10 Wget (Linux File Downloader) Command Examples in Linux
In this article, we will review the wget utility which retrieves files from World Wide Web (WWW) using widely used protocols like HTTP, HTTPS, FTP, and FTPS.
Wget is a free command-line utility and network file downloader, which comes with many features that make file downloads easy, including:
- Download large files or mirror complete web or FTP sites.
- Download multiple files at once.
- Set bandwidth and speed limit for downloads.
- Download files through proxies.
- Can resume aborted downloads.
- Recursively mirror directories.
- Runs on most UNIX-like operating systems as well as Windows.
- Unattended / background operation.
- Support for persistent HTTP connections.
- Support for SSL/TLS for encrypted downloads using the OpenSSL or GnuTLS library.
- Support for IPv4 and IPv6 downloads.
Wget Command Syntax
The basic syntax of Wget is:
$ wget [option] [URL]
First, check whether the wget utility is already installed or not in your Linux box, using the following command.
$ rpm -q wget [On RHEL/CentOS/Fedora and Rocky Linux/AlmaLinux] $ dpkg -l | grep wget [On Debian, Ubuntu and Mint]
Install Wget on Linux
If Wget is not installed, you can install it using your Linux system’s default package manager as shown.
$ sudo apt install wget -y [On Debian, Ubuntu and Mint] $ sudo yum install wget -y [On RHEL/CentOS/Fedora and Rocky Linux/AlmaLinux] $ sudo emerge -a net-misc/wget [On Gentoo Linux] $ sudo pacman -Sy wget [On Arch Linux] $ sudo zypper install wget [On OpenSUSE]
The -y option used here is to prevent confirmation prompts before installing any package. For more YUM and APT command examples and options read our articles on:
1. Download a File with Wget
The command will download a single file and store it in a current directory. It also shows download progress, size, date, and time while downloading.
# wget http://ftp.gnu.org/gnu/wget/wget2-2.0.0.tar.gz --2021-12-10 04:15:16-- http://ftp.gnu.org/gnu/wget/wget2-2.0.0.tar.gz Resolving ftp.gnu.org (ftp.gnu.org)... 209.51.188.20, 2001:470:142:3::b Connecting to ftp.gnu.org (ftp.gnu.org)|209.51.188.20|:80... connected.

2. Wget Download File with a Different Name
Using -O (uppercase) option, downloads files with different file names. Here we have given the wget.zip file name as shown below.
# wget -O wget.zip http://ftp.gnu.org/gnu/wget/wget2-2.0.0.tar.gz --2021-12-10 04:20:19-- http://ftp.gnu.org/gnu/wget/wget-1.5.3.tar.gz Resolving ftp.gnu.org (ftp.gnu.org)... 209.51.188.20, 2001:470:142:3::b Connecting to ftp.gnu.org (ftp.gnu.org)|209.51.188.20|:80... connected.

3. Wget Download Multiple Files with HTTP and FTP Protocol
Here we see how to download multiple files using HTTP and FTP protocol with the wget command simultaneously.
$ wget http://ftp.gnu.org/gnu/wget/wget2-2.0.0.tar.gz ftp://ftp.gnu.org/gnu/wget/wget2-2.0.0.tar.gz.sig --2021-12-10 06:45:17-- http://ftp.gnu.org/gnu/wget/wget2-2.0.0.tar.gz Resolving ftp.gnu.org (ftp.gnu.org)... 209.51.188.20, 2001:470:142:3::b Connecting to ftp.gnu.org (ftp.gnu.org)|209.51.188.20|:80... connected.

4. Wget Download Multiple Files From a File
To download multiple files at once, use the -i option with the location of the file that contains the list of URLs to be downloaded. Each URL needs to be added on a separate line as shown.
For example, the following file ‘download-linux.txt‘ file contains the list of URLs to be downloaded.
# cat download-linux.txt https://releases.ubuntu.com/20.04.3/ubuntu-20.04.3-desktop-amd64.iso https://download.rockylinux.org/pub/rocky/8/isos/x86_64/Rocky-8.5-x86_64-dvd1.iso https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/debian-11.2.0-amd64-DVD-1.iso
# wget -i download-linux.txt --2021-12-10 04:52:40-- https://releases.ubuntu.com/20.04.3/ubuntu-20.04.3-desktop-amd64.iso Resolving releases.ubuntu.com (releases.ubuntu.com)... 91.189.88.248, 91.189.88.247, 91.189.91.124, ...

If your URL list has a particular numbering pattern, you can add curly braces to fetch all the URLs that match the pattern. For example, if you want to download a series of Linux kernels starting from version 5.1.1 to 5.1.15, you can do the following.
$ wget https://mirrors.edge.kernel.org/pub/linux/kernel/v5.x/linux-5.1.{1..15}.tar.gz

5. Wget Resume Uncompleted Download
In case of big file download, it may happen sometimes to stop download in that case we can resume downloading the same file where it was left off with -c option.
But when you start downloading files without specifying -c an option wget will add .1 extension at the end of the file, considered as a fresh download. So, it’s good practice to add -c switch when you download big files.
# wget -c https://releases.ubuntu.com/20.04.3/ubuntu-20.04.3-desktop-amd64.iso --2021-12-10 05:27:59-- https://releases.ubuntu.com/20.04.3/ubuntu-20.04.3-desktop-amd64.iso Resolving releases.ubuntu.com (releases.ubuntu.com)... 91.189.88.247, 91.189.91.123, 91.189.91.124, ...

6. Wget Mirror Entire Website
To download or mirror or copy an entire website for offline viewing, you can use use the following command that will make a local copy of the website along with all the assets (JavaScript, CSS, Images).
$ wget --recursive --page-requisites --adjust-extension --span-hosts --convert-links --restrict-file-names=windows --domains yoursite.com --no-parent yoursite.com
Explanation of the above command.
wget
--recursive # Download the whole site.
--page-requisites # Get all assets/elements (CSS/JS/images).
--adjust-extension # Save files with .html on the end.
--span-hosts # Include necessary assets from offsite as well.
--convert-links # Update links to still work in the static version.
--restrict-file-names=windows # Modify filenames to work in Windows as well.
--domains yoursite.com # Do not follow links outside this domain.
--no-parent # Don't follow links outside the directory you pass in.
yoursite.com/whatever/path # The URL to download
7. Wget Download Files in Background
With -b option you can send a download in the background immediately after the download starts and logs are written in the wget.log file.
$ wget -b wget.log https://releases.ubuntu.com/20.04.3/ubuntu-20.04.3-desktop-amd64.iso Continuing in background, pid 8999. Output will be written to ‘wget.log’.
8. Wget Set File Download Speed Limits
With option --limit-rate=100k, the download speed limit is restricted to 100k and the logs will be created under wget.log as shown below.
$ wget -c --limit-rate=100k -b wget.log https://releases.ubuntu.com/20.04.3/ubuntu-20.04.3-desktop-amd64.iso Continuing in background, pid 9108. Output will be written to ‘wget-log’.
View the wget.log file and check the download speed of the wget.
$ tail -f wget-log 5600K .......... .......... .......... .......... .......... 0% 104K 8h19m 5650K .......... .......... .......... .......... .......... 0% 103K 8h19m 5700K .......... .......... .......... .......... .......... 0% 105K 8h19m 5750K .......... .......... .......... .......... .......... 0% 104K 8h18m 5800K .......... .......... .......... .......... .......... 0% 104K 8h18m 5850K .......... .......... .......... .......... .......... 0% 105K 8h18m 5900K .......... .......... .......... .......... .......... 0% 103K 8h18m 5950K .......... .......... .......... .......... .......... 0% 105K 8h18m 6000K .......... .......... .......... .......... .......... 0% 69.0K 8h20m 6050K .......... .......... .......... .......... .......... 0% 106K 8h19m 6100K .......... .......... .......... .......... .......... 0% 98.5K 8h20m 6150K .......... .......... .......... .......... .......... 0% 110K 8h19m 6200K .......... .......... .......... .......... .......... 0% 104K 8h19m 6250K .......... .......... .......... .......... .......... 0% 104K 8h19m ...

To download a file from a password-protected HTTP server, you can use the options --http-user=username and --http-password=password as shown.
$ wget --http-user=narad --http-password=password http://http.example.com/filename.tar.gz
10. Wget Ignore SSL Certificate Check
To ignore the SSL certificate check while downloading files over HTTPS, you can use the --no-check-certificate option:
$ wget --no-check-certificate https://mirrors.edge.kernel.org/pub/linux/kernel/v5.x/linux-5.1.1.tar.gz --2021-12-10 06:21:21-- https://mirrors.edge.kernel.org/pub/linux/kernel/v5.x/linux-5.1.1.tar.gz Resolving mirrors.edge.kernel.org (mirrors.edge.kernel.org)... 147.75.95.133, 2604:1380:3000:1500::1 Connecting to mirrors.edge.kernel.org (mirrors.edge.kernel.org)|147.75.95.133|:443... connected.
