在linux下重启tomcat的脚本

第一种脚本： 

#/bin/sh
java=$(ps -aux |grep java |sed -n  '1p' |awk '{print $2}');
kill -9 $java;
rm /usr/local/tomcat-5.0.28/logs/catalina.* -rf
rm /usr/local/tomcat-5.0.28/work/Catalina/ -rf
sh /usr/local/tomcat-5.0.28/bin/startup.sh
tail -f /usr/local/tomcat-5.0.28/logs/catalina.*

第二种脚本（这种功能比较厉害一点，不是很懂这种启动）： 
#!/bin/sh 
# ----------------------------------------------------------------------------- 
# Start Script for the CATALINA Server
