get info on installed tomcat

If you don't know where catalina.sh is (or it never gets called), you can usually find it via ps:

ps aux | grep catalina

From the ps output, you can see both catalina.home and catalina.base

catalina.home is where the Tomcat base files are installed, and catalina.base is where the running configuration of Tomcat exists.

run:

/usr/share/tomcat8/bin/version.sh
