Catalina.bat是tomcat所有脚本中最重要的脚本，完成几乎所有的tomcat操作。如启动，关闭等等,都是由catalina.bat脚本来完成的。接下来，我将对Tomcat catalina.bat脚本进行分析。

　　echo   run -security     Start in the current window with security manager
echo   start             Start Catalina in a separate window
echo   start -security   Start in a separate window with security manager
echo   stop              Stop Catalina
echo   version           What version of tomcat are you running?
goto end

:doDebug
shift                    将%2里的值转到%1
set _EXECJAVA=%_RUNJDB%  将变量 _EXECJAVA设为_RUNJDB变量的值
set DEBUG_OPTS=-sourcepath "%CATALINA_HOME%\..\..\jakarta-tomcat-catalina\catalina\src\share"
设定DEBUG_OPTS变量

if not ""%1"" == ""-security"" goto execCmd
如果%1不为-security，转到execCmd位置

shift       将%2里的值转到%1
echo Using Security Manager       输出该行
set SECURITY_POLICY_FILE=%CATALINA_BASE%\conf\catalina.policy
设定SECURITY_POLICY_FILE变量的值

goto execCmd     转到execCmd位置

:doRun
shift        将%2里的值转到%1
if not ""%1"" == ""-security"" goto execCmd   如果%1不为-security，转到execCmd位置
shift        将%2里的值转到%1
echo Using Security Manager   输出该行
set SECURITY_POLICY_FILE=%CATALINA_BASE%\conf\catalina.policy
设定SECURITY_POLICY_FILE变量的值

goto execCmd  转到execCmd位置

:doStart
shift        将%2里的值转到%1
if not "%OS%" == "Windows_NT" goto noTitle  如果OS变量不为Windows_NT，转到noTitle
set _EXECJAVA=start "Tomcat" %_RUNJAVA%       设定_EXECJAVA变量的值
goto gotTitle      转到gotTitle位置
:noTitle
set _EXECJAVA=start %_RUNJAVA%    设定 _EXECJAVA 变量的值
:gotTitle
if not ""%1"" == ""-security"" goto execCmd   如果%1不为-security，转到execCmd位置
shift                    将%2里的值转到%1
echo Using Security Manager        输出该行
set SECURITY_POLICY_FILE=%CATALINA_BASE%\conf\catalina.policy
设定SECURITY_POLICY_FILE变量的值

goto execCmd       转到execCmd位置

:doStop
shift                 将%2里的值转到%1
set ACTION=stop       将ACTION的变量设为stop
