Example 2: Downloading a Single File with a Different Name

Using the wget command with the -O (Upper Case)  option, you can download a single file under a different name from your terminal. To do so you may run the wget command with the below syntax:

Wget -O <URL>

For instance, I will again download the homepage of the linuxsimply website. However, this time, I will save it as “homepage.html” using the below command:

wget -O homepage.html https://linuxsimply.com/

In this image, you can see that I have downloaded the desired homepage using the wget command. It has been saved in my current directory as “homepage.html”.

Example 3: Downloading Multiple Files

Using the wget command, you can download multiple files at once. You will be able to download from both HTTP and FTP protocols in a single command. The typical syntax is:

wget <URL1> <URL2>

In this example, I will download both the homepage and commands page of the linuxsimply website. To do the same, run the command in the following:

wget https://linuxsimply.com/ https://linuxsimply.com/commands/

In this image, you can see that I have downloaded both the homepage and command page using the wget command. The homepage has been saved in my current directory as “index.html” and the command page has been saved as “index.html.1”.

Example 4: Download Multiple Files from Another File

You can use a particular file to download single or multiple files using the -i option with the wget command. The links found in this file will be downloaded directly to your system. You may use a TEXT or HTML file. In this example, I will download 3 pdf files from the URLs provided in the “text.txt” file. In this case, the URLs must be written in separate lines.  To do so you can follow the given syntactical format:

wget -i  <File>

You may type the following command and press ENTER to achieve a similar result like mine:

wget -i text.txt

In this image, you can see that I have downloaded 3 pdf files using the wget command. The files were downloaded on my machine serially one after another.

Example 5: Downloading Files to a Specific Directory

You can download files in your desired location using - P (Upper Case) option with the wget command. In this example, I will download the “50 Most Used Linux Commands pdf.pdf” file from the linuxsimply website to my Documents directory. To do so, follow the given syntax employing wget:

wget -P <path> <File>

Similarly, you may execute this command to download the above-mentioned .pdf file in the “Documents” directory using wget:

wget -P Documents https://linuxsimply.com/wp-content/uploads/2022/11/50-Most-Used-Linux-Commands-pdf.pdf

In this image, you can see that I have downloaded the file to my desired location using the wget command. Then, I listed the contents of the Documents directory using the ls command to see the downloaded file.

Example 6: Downloading Files in the Background

Using the wget command with the option -b you can download files in the background. You can be disconnected while the download occurs. The output will be saved in a different file in the current directory along with the file. You can open the specific log file to see the downloading details. In this example, I will download the “Bash Terminal Keyboard Shortcuts for Editing.pdf” file from the linuxsimply website. To do so you can go through the following syntax:

wget -P <path> <File>

Let’s see the below command to see how it works:

wget -b https://linuxsimply.com/wp-content/uploads/2022/11/Bash-Terminal-Keyboard-Shortcuts-for-Editing.pdf

In this image, you can see that I am downloading the mentioned file in the background using the wget command. The output for my command was saved in the “wget-log.1” file in my current directory.

Example 7: Limiting File Download Speed

Using the wget command with the option -- limit-rate you can limit the downloading speed. To do so you can go through the following syntax:

wget --limit-rate=[value] <File>

Now, as an example, I will download the Emacs Editor Keybindings or Shortcuts.pdf file from the linuxsimply with a limited bandwidth of 50KBs running the following command on the prompt:

wget --limit-rate=50k https://linuxsimply.com/wp-content/uploads/2022/12/Emacs-Keybindings-or-Shortcuts-in-Linux.pdf

So, in this image, you can see that I am downloading the mentioned file with a bandwidth of almost 50KB/s using the wget command.

Example 8: Resuming Unfinished Downloads

You can resume your unfinished downloads with option -c of the wget command. In this example, I retrieved the partially downloaded homepage of the linuxsimply website. At first, I interrupted my ongoing download by pressing CTRL+Z. Then, I resumed downloading using the -c option. To do so you can go through the following syntax:

wget -c <File>

You can run the following command to achieve similar results using the wget command:

wget -c https://linuxsimply.com/

In this image, you can see that the first downloading attempt was interrupted. Then I retrieved the partially downloaded file using the wget command.

Example 9: Downloading files recursively

You can download files recursively with option -r of the wget command. In this example, I want to download all the files from the Free downloads page of the linuxsimply website recursively. You may do so by following the given syntax:

wget -r <URL>

Now, You may follow the given example to execute this command:

wget -r https://linuxsimply.com/free-downloads/

In this image, you can see that at first without any option the wget command downloaded only the Free downloads page and saved it as “index.html.1”. I used the -r option to download all the files recursively. Since the downloads will take a lot of time I am doing it in the background with option -b and saving the output in the “wget-log” file. You can see the latest download output by typing the command tail before your log file. My output shows that the downloads are still occurring recursively with the wget command in Linux.

Example 10: Selecting Certain File Types While Downloading

You can select certain types of files while downloading with the option -A/--Accept of the wget command. In this example, I want to download only the .pdf files from the Free downloads page of the Linuxsimply website. The full syntax is:

wget -A”.FileType” <URL>

Let’s see an example of running wget command to download the pdf files from Linuxsimply website:

wget -A”*.pdf”  https://linuxsimply.com/free-downloads/

In this image, you can see that I used the -A option along with the -r option. This is because the command needs to look recursively for the .pdf files. The wget command with the -A option saves each file. If the file does not match .pdf extension, it removes that file immediately. In this way, I am downloading only the .pdf files from the Free downloads page.

Example 11: Rejecting a Certain File Type While Downloading

You can reject certain types of files while downloading with the option -R/--Reject of the wget command. In this example, I want to reject downloading files with .tmp, .html, .css, and .js extensions from the Free downloads page of the Linuxsimply website. You can follow the syntax below to do so:

wget -R FileType/s  <URL>

Here’s the example of rejecting downloading the files I mentioned earlier using wget -R:

wget -R tmp,html,css,js  https://linuxsimply.com/free-downloads/

In this image, you can see that I used the -R option along with the -r option. This is because the command needs to look recursively for the .tmp, .html, .css, and .js extensions. The wget command with the -R option saves each file. If the file matches with any of the .tmp, .html, .css, and .js extensions, it removes that file immediately. In this way, I am not downloading .tmp, .html, .css, and .js files from the Free downloads page.

Example 12: Setting Numbers of Retrying Attempts to Download

Using the wget command with the -t/--tries option, you can set the number of retrying attempts for interrupted downloads. In this example, I set the number of attempts to 2. The wget command will try to download the file twice if it faces any interruptions.

wget --tries=[number] <File> 

You may run the given command and set the number of retrying attempts to 2:

wget -tries=2 --limit-rate=50k  https://linuxsimply.com/wp-content/uploads/2022/12/Untitled-design.gif

In this image, you can see that I have fixed the retry attempts for download to 2. I also limited the bandwidth to 50KB/s. The desired file got interrupted after downloading 60%. The wget command tried to retrieve the file twice. After 2 failed attempts the downloading process stopped.

Example 13: Mirroring an Entire Website

Using the wget command with the -m/--mirror option, you can download a full website on your local machine. This is called mirroring a website. You will be able to browse the mirrored website remotely even when you are offline. In this example, I will mirror the Linuxsimply website. To do so you can follow the syntax below:

wget --mirror -p --convert-links <website_URL> 

So, to mirror the entire website named, Linuxsimply, run the following command:

wget --mirror -p --convert-links -P Downloads  https://linuxsimply.com/

So, in the first image, you can see that I have downloaded the desired website in my Downloads directory using the wget command. It mirrored all the hierarchy and files for local browsing in my system. In this image, you can see the local version of the downloaded website.

Example 14: Ignoring SSL Certification Check While Downloading

Using the wget command with the option --no-check-certificate ,you can avoid the SSL certification check of HTML websites. In this example, I will download the homepage of the SOFTEKO website without checking the certificate. The complete syntax is:

wget --no-check-certificate  <URL>

Now, run the following command and ignore the SSL certification check like the example I mentioned above:

wget --no-check-certificate https://www.softeko.co/

In this image, you can see that I am downloading the mentioned website ignoring its SSL certification check using the wget command. The webpage was saved as “index.html.1” in my current directory.

Conclusion

In this article, I have tried to show you the frequent uses of the wget command in Linux. You can always combine one or more options demonstrated here to get a full experience. I hope these practical examples will help you through your journey with the command line and make you a power user of LINUX.
