我的业务是，根据关键字和日志级别以及日志时间分页过滤并返回查询到的日志，我使用下面两个查询，结果差异很大（不加关键字根本查询不出来）
第一个（有关键字、日志日期、日志级别INFO，能查询出来）：

awk 'BEGIN{i=1;j=i+99}
{
    isFirst = -1;
    longDate= ""; 
    paramDate="";
    if(match($1, /[0-9]{4}-[0-9]{2}-[0-9]{2}/)>0)
    {
        isFirst = 1;
        split($2, arr, ".");
        ymd=$1;
        hms=arr[1];
        gsub("-", " ", ymd);
        gsub(":", " ",hms);
        newDate = (ymd" "hms);
        longDate =  mktime(newDate);
        paramDate=mktime(/2020 07 22 13 03 34/);
    } else if(match($2, /[0-9]{4}-[0-9]{2}-[0-9]{2}/)>0)
    {
        isFirst = 0;
        split($3, arr, ".");
        ymd=$2;
        hms=arr[1];
        gsub("-", " ", ymd);
        gsub(":", " ",hms);
        newDate = (ymd" "hms);
        longDate =  mktime(newDate);
        paramDate=mktime(1);
    }
    if(longDate >= paramDate && $0  ~ /mrcp_client.c/ && i<=j && isFirst != -1)
    {
        if(isFirst == 1)
        {
            if($3 ~ /INFO/)
                print $0 
            }else
            {
                if($4 ~ /INFO/)
                {
                    $1=""; 
                    print $0
                }
            }
            i=i+1;
        }
    }' /usr/local/freeswitch/log/freeswitch.log

第二个（无查询的关键字，仅仅根据日志级别INFO、日志时间去查询，直接查询不到）：

awk 'BEGIN{i=1;j=i+99}
{
    isFirst = -1;
    longDate= ""; 
    paramDate="";
    if(match($1, /[0-9]{4}-[0-9]{2}-[0-9]{2}/)>0)
    {
        isFirst = 1;
        split($2, arr, ".");
        ymd=$1;hms=arr[1];
        gsub("-", " ", ymd);
        gsub(":", " ",hms);
        newDate = (ymd" "hms);
        longDate =  mktime(newDate);
        paramDate=mktime(/2020 07 22 13 03 34/);
    } else if(match($2, /[0-9]{4}-[0-9]{2}-[0-9]{2}/)>0)
    {
        isFirst = 0;
        split($3, arr, ".");
        ymd=$2;hms=arr[1];
        gsub("-", " ", ymd);
        gsub(":", " ",hms);newDate = (ymd" "hms);
        longDate =  mktime(newDate);
        paramDate=mktime(1);
    }if(longDate >= paramDate && i<=j && isFirst != -1)
    {
        if(isFirst == 1)
        {
            if($3 ~ /INFO/)
            {
                print $0 
            }else
            {
                if($4 ~ /INFO/)
                {
                    $1=""; 
                    print $0
                }
            }
            i=i+1;
        }
    }' /usr/local/freeswitch/log/freeswitch.log

这两个查询只有一个地方有差异，那就是在

if(longDate >= paramDate && $0 ~ /mrcp_client.c/ && i<=j && isFirst != -1)

一直搞不明白，为什么一个能查出来，一个就查不出来呢，是我的语法不标准吗？还请大佬们指点下。
