清理内容脚本

话说写一个脚本也真是不容易，语法什么的，参数什么的，标点符号什么的都要用的恰到好处才能准确执行呀。真是不容易。

path2="/opt/jboss/jboss-5.1.0.GA/server/sesb2mgmt/log"

for path in ${path1} ${path2} ${path3}

do

    Time=`date '+%Y%m%d_%H%M'`

    echo "==================${Time}_start_cleanlog=================="

    ls -ltr ${path}

    if [ `du -sm ${path} | awk '{print $1}'` -ge 900 ]

    then

        cd ${path}

        if [ `ls -l ${path} | wc -l` -ge 5 ]

        then

            rm -rf `ls -rt ${path}|head -n2`

        fi

        for i in `find ${path} -type f`

        do

        cat /dev/null > ${i};

        done

    exit 0
