# echo 命令是在现实器上显示一段文字，下面就是把变量project_name打印出来
echo $project_name
echo $tomcat_home
echo $link_tomcat
# 显示今天，日期格式设置
today=`date +%Y-%m-%d`
# ps -ef 是显示所有进程，通过 grep筛选出您所需要的进程
# ps -ef | grep ${link_tomcat} 则表示显示${link_tomcat}这个变量的进程，当然这个变量我是在jenkins中配置的。
# grep -v grep命令是去掉grep命令自身
# awk '{print $2}' 截取 $2 第二个域的pid号
# kill -9 强杀进程
# xargs 使用上一个操作的结果作为下一个命令的参数使用
ps -ef | grep ${link_tomcat} | grep -v grep | awk '{print $2}'| xargs kill -9
