杀掉tomcat进程后仍然端口占用的脚本

	#!/bin/bash

	getPid
	echo 'pid: ' $pid
	if [ $pid ];then
		$tomcat_home/shutdown.sh

	sleep 1

		kill -9 $pid
	fi
	echo ' gateway restart...'
	netstat_status=true
	client_num=`netstat -anp |grep $port|wc -l`

在指定目录下jar包内搜索文件

	#!/bin/bash
	# sh class_file [path] file_name 
	file_name=''
	if [ $# -gt 1 ];then
		 cd $1
		 file_name=$2
	else
		 file_name=$1
	fi
	find $path -name "*.jar" -type f > /tmp/jar.txt
	for item in $(cat /tmp/jar.txt)
	do 
	    jar -tvf $item |grep  $file_name
	    if [ $? -eq 0 ]; then
	       echo "the jar file is $item"
	    fi
	done
