shell脚本启动java程序

#!/bin/bash

### 切换到工作目录
bin=$(cd `dirname ${0}`;pwd)
cd ${bin}
echo "bin [${bin}] .."

### 参数设置
process="RCrNew"
LOGPATH="/web/logs"
day=$(date +%Y%m%d)
#instance=$(echo ${bin}|awk -F'/' '{print $NF}')

### 如果程序已存在，先退出再执行
#if [ $(ps -ef|grep -v grep|grep ${process}|grep ${instance}|grep -Ewv "less|tail|tailf"|wc -l) -ne 0 ]
if [ $(ps -ef|grep -v grep|grep ${process}|grep -Ewv "less|tail|tailf"|wc -l) -ne 0 ]
then
    ps -ef|grep -v grep|grep ${process}|grep -Ewv "less|tail|tailf"
    echo "${process} instance: ${instance} is exists,Please kill it and run agin"
    exit
fi

### JAVA相关参数设置

echo -e "jar_lib: [ ${jar_lib} ]\njar_program: [ ${jar_program} ]\nmainClass: [ ${MAINCLASS} ]"

### 执行程序
echo "${JAVA} ${JAVA_OPTS} -cp ${JARS} ${MAINCLASS}"
