The thing you are going to learn today can be risky. Please use this method with your own website. Without taking permission downloading content can be illegal. Today you are going to learnr the You can copy any website easily. To copy a website, you need to have some knowledge of Linux related things. No, any issue I was taught by someone today, I'll share that with you. This would be the quick tutorial with the List of Commands.
All you need is the Internet and 2 android application or a Linux terminal with the internet. To know about Termux and Termux API you can click here.

pkg install termux -y

sudo apt install wget -y

sudo yum install wget

Now run a simple command to copy the entire website. It can take some time depends on the number of posts on that website.

wget -r websitelink.com

For example, if I wish to download my website, I would do certain things.
First Install Termux and Termux API (to do that please click on the above link).
Install wget using the command above.
Then I would run a command in the terminal listed below:

wget -r uk2blogger.blogspot.com
or
wget --mirror --convert-links --page-requisites  https://listofcommands.blogspot.com/
or
wget --mirror -p --convert-links -P ./Local-Folder website.com
or
wget -m -k -p webSite.com 
or
wget ‐‐limit-rate=20k ‐‐wait=60 ‐‐random-wait ‐‐mirror site-download.com
or
wget -m -r -linf -k -p -q -E -e robots=off site.com

It will automatically start to download each link one by one. That is enough to know about downloading a website. I'd suggest you try this command only for a known website. If you try it with some unknown websites that may be illegal and I'm not responsible for that.
