This quick tutorial will help you to find Apache Tomcat version on any Linux-based operating system.

Check Tomcat Version

1. Use the cd command to switch to the Tomcat installation bin directory. The location of the directory depends on the installation types. The packages installed on the official repository are generally installed under the /etc/tomcat directory. Custom installation is generally done under the /opt or /usr/share directory.

   cd /usr/share/tomcat/bin 
   

   Note: If you still have not found the directory, I have discussed a few methods at the end of this article.

2. You will find a version.sh script under the bin directory. You can execute this script to find the installed Tomcat version along with a few other details.

   ./version.sh

   Using CATALINA_HOME:   /usr/share/tomcat

   Using JRE_HOME:        /usr
   Using CLASSPATH:       /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jar
