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
MAINCLASS="com.yyyy.app.RCNew"
JAVA="$JAVA_HOME/bin/java"
JAVA_OPTS="-server -Xms1024m -Xmx1024m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:MaxPermSize=128m "
JARS1=`find -L "${bin}/dependency" -name "*.jar" -printf '%p:'`
JARS2=$(ls -rt *jar|tail -1)
JARS=${JARS1}${JARS2}
echo -e "JARS2: [ ${JARS2} ]\nmainClass: [ ${MAINCLASS} ]"
# echo -e "JARS1: [ ${JARS1} ]\nJARS2: [ ${JARS2} ]\nmainClass: [ ${MAINCLASS} ]"
# echo -e "JARS: [ ${JARS} ]"

### 执行程序
nohup ${JAVA} ${JAVA_OPTS} -cp ${JARS} ${MAINCLASS} 1>/dev/null 2>&1 &
if [ $? -eq 0 ]
then
    echo "${process} run successful"
else
    echo "${process} run fail"
