To find out the Tomcat version, we need to find the file – version.sh (unix) or version.bat (windows). The file is usually found in the Tomcat bin folder.

To find the version.sh file: sudo find / -name "version.sh"

Find out everything about Tomcat (where name = server name): sudo find / -name "apache-tomcat8"
