To find out the Tomcat version, find this file – version.sh for *nix or version.bat for Windows. This version.sh file is normally located in the Tomcat bin folder.
For example :
mkyong@hcompass:/usr/share/tomcat7/bin$ ./version.sh
Using CATALINA_BASE: /usr/share/tomcat7
Using CATALINA_HOME: /usr/share/tomcat7
Using CATALINA_TMPDIR: /usr/share/tomcat7/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/share/tomcat7/bin/bootstrap.jar:/usr/share/tomcat7/bin/tomcat-juli.jar
Server version: Apache Tomcat/7.0.28
Server built: Apr 8 2014 08:47:08
Server number: 7.0.28.0
OS Name: Linux
OS Version: 3.15.4-x86_64-linode45
Architecture: amd64
JVM Version: 1.7.0_55-b14

In this example, Tomcat version is 7.0.28
Note
If you are not sure where is the version.sh file, try this command :
sudo find / -name "version.sh"
Find out everything about Tomcat.
sudo find / -name "tomcat7"

Hi,
Is there a tool available to identify the version we are using. I am upgrading the application to the latest TOMCAT version but just want to know if any of the older files are used or not. Can you provide some pointers to this?
try writing a python/bash script to find all the tomcat version installed in your host
Thanks for the information. This is helpful.
MK Yong, your tomcat and hibernate tutorials have been invaluable to me. Thanks man!
Thanks Mkyong,
How about in Windows envirunment? what is the command to know the TOMCAT version?
Thanks in advance

Try parsing or executing the Tomcat_home/bin directory and look for a script named “version.sh” OR “version.bat” depending on your operating system.For windows its “version.bat”..
