Lab run tomcat issue

I am having trouble running the tomcat in my terminal. It says no command found. I have attached the screenshot of my terminal below. Please let me know what I did wrong. Thank you in advance.

It is fine

Do you have any ideas why its not running on my PC

In that lab, run these commands exactly in order

sudo curl -OL https://downloads.apache.org/tomcat/tomcat-8/v8.5.97/bin/apache-tomcat-8.5.97.tar.gz
sudo tar -xf apache-tomcat-8.5.97.tar.gz
sudo mv apache-tomcat-8.5.97 /opt/apache-tomcat-8
sudo /opt/apache-tomcat-8/bin/startup.sh
