# for i in /usr/local/tomcat/目录下的每个Tomcat的名字，例：tomcat-mune 即 for i in mune，配合下面的$i取值
# 多个Tomcat时，则：for i in mune mune2 mune3，即在/usr/local/tomcat/目录下拥有tomcat-mune，tomcat-mune2，tomcat-mune3三个Tomcat服务
# 单个Tomcat时可直接替换为Tomcat所在的绝对路径

for i in mune
do
cat /usr/local/tomcat/tomcat-$i/logs/catalina.out > /usr/local/tomcat/tomcat-$i/logs/catalina.out.$YESTERDAY.back
> /usr/local/tomcat/tomcat-$i/logs/catalina.out
