[
    {
        "id":"1"
    },
    {
        "data":"231566"
    },
    {
        "id":"2"
    },
    {
        "data":"12345515"
    },
    {
        "id":"3"
    },
    {
        "data":"4124412512"
    }
    {
        "id":"4"

    {
        "data":"4231aaa24412512"

    },
    {
        "data":"4124423zsds12512"
    }

#过滤命令如下：

cat test.txt |grep -vE ‘({|}|\[|\])‘|cut -d: -f 2| cat test2.txt |grep -vE ‘({|}|\[|\])‘|cut -d: -f 2|sed ‘:a;N;$!ba;s/\n/ /g‘|awk ‘BEGIN{print"\n设置计数 器t=1";t=1}{for(i=1;i<NF;i++)if((i%2)!=0){t++;print "key:"$i,"valuse:"$(i+1)} else continue}END{print "循环次数:"t}‘
