Thank you for the link. But what’s your question? Did you have a problem with the lab?
yes sir . How to install tomcat and also what is the difference between curl and wget command
If you follow the “Tomcat” link (it’s in the right upper side of the screen) you’ll find this page, which has instructions. You’ll need to:
- Make sure you have a compatible version of java installed.
- Down load the file https://downloads.apache.org/tomcat/tomcat-11/v11.0.8/bin/apache-tomcat-11.0.8.tar.gz
- Untar the file and copy the resulting directory to /opt/apache-tomcat-11.
You can use wget or curl to download the tar ball to the lab’s system. wget is a little easier to do this with, since less arguments are needed. If you click on the 
icon, you’ll get more details on the solution.
