Linux中，shell脚本调用java程序模板

运行某个shell的时候检测这个shell当前是否运行，如果正在运行，退出，否则，开始运行。

#!/bin/bash

cd /a/b/c/bin

Channel=$1

BatchSize=80000

export HOMEDIR=/a/b/c

export CLASSPATH=$JAVA_HOME/lib/tools.jar:$HOMEDIR/lib/mysql.jar

export JAVA_HOME=/usr/lib/jvm/java-1.6.0

export JAVA_CMD=$JAVA_HOME/bin/java

export LOGDIR=/a/b/logs/

export LOGFILE=$LOGDIR/Process-`date +"%Y%m%d"`.log

mkdir -p $LOGDIR

export JAVA_MAIN=com.test.Test

EXEC_CMD="$JAVA_CMD -Xmx6000m -classpath $CLASSPATH $JAVA_MAIN $Channel"

ps -ef | grep "$EXEC_CMD" > Status_$Channel

num=$(wc -l Status_$Channel | awk '{print $1}')

if [ $num -gt 1 ]

then

        echo "process is running..." >> $LOGFILE

        exit 1

else

        echo "Start to process For "$Channel" at:"`date +%Y-%m-%d-%H:%M:%S` >> $LOGFILE 

        $EXEC_CMD $BatchSize >> $LOGFILE 

        echo "End to process For "$Channel" at:"`date +%Y-%m-%d-%H:%M:%S` >> $LOGFILE

fi

note:jar包的main函数可以接受两个参数，一个是Channel，另一个是BatchSize.
