【Linux查看tomcat版本】
一、不同的tomcat查看版本可能不同，例如有的直接执行./就可以，其他就没有；一般来说，在tomcat启动时就会有版本信息，如：
信息: Initializing Coyote HTTP/1.1 on http-8023
2009-5-6 16:38:09 load
信息: Initialization processed in 1673 ms
2009-5-6 16:38:10 start
信息: Starting service Catalina
2009-5-6 16:38:10 start
信息: Starting Servlet Engine: Apache Tomcat/6.0.16
另外还可以在以下文件中找到，但据tomcat版本不一样，文件位置稍有差异：
Tomcat5：tomcat_home\server\lib\ org\apache\catalina\util\
Tomcat6：tomcat_home \lib\ org\apache\catalina\util\ (这里的两个jar包可以下载下来用rar打开然后再查看。)
