10 Wget (Linux File Downloader) Command Examples in Linux

In this article, we are going to 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.

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 in 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

2. Wget Download File with Different Name

Using -O (uppercase) option, downloads files with the 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

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 at once.

$ 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

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

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

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 download in the background immediately after download start and logs are written in 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

$ wget --ftp-user=narad --ftp-password=password ftp://ftp.example.com/filename.tar.gz

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

  2. We are facing slowness when we are sending traffic using wget in linux machines through TCL .
    Traffic passing gets struck in the middle when the file size is more than 100MB.
    Hence we are unable to meassure the bandwidth during download.
    Please suggest any way to address this issue.

  3. Hi…

    I want to make a script to check a website and download the latest available version of a deb file and install it.

    The problem I have is that on the website, each time the version changes, so the file name is changed, so I can not know the exact name to give the order to wget.

    I wonder if there is any way to include wildcards in wget, or similar option.

    As an example, suppose you want to download each x time the latest “Dukto” in 64 bits.

    Their website is:
    http://download.opensuse.org/repositories/home:/colomboem/xUbuntu_12.04/amd64/dukto_6.0-1_amd64.deb

    How i can tell wget to look in that directory and download the dukto*.deb?

    Thanks in advance.

    • That means it will go through all the links on the website. So, for example, if you have a website with links to more websites then it will download each of those and any other links that are in that website. You can set the number of layers, etc (reference http://www.gnu.org/software/wget/manual/html_node/Recursive-Retrieval-Options.html ). This is actually how google works but for the whole internet, it goes through ever link on every website to every other one. Also, if you use some more commands you can actually download a whole site and make it suitable for local browsing so if you have a multipage site that you use often, you could set it recursive and then open it up even without an internet connection. I hope that makes sense(the tl;dr version is that it follows every link on that website to more links and more files in a ‘tree’)
