while read line # 消耗stdin
do
        echo "$line"
        if [ "$loop" -gt 999999 ];then
                exit 0;
        fi

        let "loop +=1"
        `echo "line $line " >> /var/log/apache2/log.log`
done

 

主要是红色行.

将得到echo的字符

root@test# echo "dkdkkd" | /var/test/test.sh "dkjfjfj"

绿字可以使用s*或是$数字来获取
