嗨，我正在尝试制作一个脚本，该脚本将为我提供新闻组活动的摘要。到目前为止，除了我尝试使用匹配运算符来查看这个 $6 字段是否与表达式匹配时，它的大部分都可以工作。我想把所有的戒指都放在一个部分下。这是我的脚本的样子：

新闻阅读.awk：

BEGIN{
print "\t\t\tNews Reader Summary\n\n"
printf("               %-15s%-15s%-15s%-15s\n\n","lonestar","runner","ringer","rings"); 
articles[4];
groups[4];
times[4];
cs2413[4];cs2413d[4];
}

NR == 1 {date1 = $1 " " $2 " " $3}

$6 == "lonestar.jpl.utsa.edu"{
    if ($7=="group"){
        articles[1]+=$9;
        if ($8=="utsa.cs.2413"){
            cs2413[1]+=$9;
        }
        if ($8=="utsa.cs.2413.d"){
            cs2413d[1]+=$9;
        }
    }else if ($7 == "exit"){
        articles[1]+=$9;
        groups[1]+=$11;
    }else {
        times[1]+=$13;
    }
}

$6 == "runner.jpl.utsa.edu"{
    if ($7=="group"){
                articles[2]+=$9;
         if ($8=="utsa.cs.2413"){
                        cs2413[2]+=$9;
                }
                if ($8=="utsa.cs.2413.d"){ 
                        cs2413d[2]+=$9;
                }

        }else if ($7 == "exit"){
                articles[2]+=$9;
                groups[2]+=$11;
        }else {
                times[2]+=$13;
        }

}

$6 == "ringer.cs.utsa.edu"{
    if ($7=="group"){
                articles[3]+=$9;
         if ($8=="utsa.cs.2413"){
                        cs2413[3]+=$9;
                }
                if ($8=="utsa.cs.2413.d"){ 
                        cs2413d[3]+=$9;
                }

        }else if ($7 == "exit"){
                articles[3]+=$9;
                groups[3]+=$11;
        }else {
                times[3]+=$13;
        }

}

$6 ~ "/ring??.cs.utsa.edu/"{
    if ($7=="group"){
                articles[4]+=$9;
         if ($8=="utsa.cs.2413"){
                        cs2413[4]+=$9;
                }
                if ($8=="utsa.cs.2413.d"){ 
                        cs2413d[4]+=$9;
                }

        }else if ($7 == "exit"){
                articles[4]+=$9;
                groups[4]+=$11;
        }else {
                times[4]+=$13;
        }

}
END{
    date2 = $1 " " $2 " " $3
    printf("Articles:      %-15d%-15d%-15d%-15d\n",articles[1],articles[2],articles[3],articles[4]); 
    printf("Groups:        %-15d%-15d%-15d%-15d\n",groups[1],groups[2],groups[3],groups[4]); 
    printf("Cs2413:        %-15d%-15d%-15d%-15d\n",cs2413[1],cs2413[2],cs2413[3],cs2413[4]); 
    printf("Cs2413.d:      %-15d%-15d%-15d%-15d\n",cs2413d[1],cs2413d[2],cs2413d[3],cs2413d[4]); 
    printf("User Time:     %-15d%-15d%-15d%-15d\n",times[1],times[2],times[3],times[4]);  
    printf("\nStart Time = %s\tEnd Time = %s\n",date1,date2); 

}

这是 news.notice 的一个片段：

我正在使用这个命令：

awk -f newsread.awk news.notice > newsread.summary

这里是 newsread.summary：

            News Reader Summary


               lonestar       runner         ringer         rings

Start Time = Feb 13 21:27:14    End Time = Feb 14 20:56:49

它必须是一个 awk 脚本。

首先摆脱引号，即不是这个：

$6 ~ "/ring??.cs.utsa.edu/"

但是这个：

$6 ~ /ring??.cs.utsa.edu/

引号分隔字符串，斜线分隔常量 RE。

现在，我怀疑您的 RE 是错误的，因为??它表示前面字符的 0 次或 1 次重复，然后再次相同或文字问号（不确定哪个 - 两种方式都没有意义）并且.表示“任何单个字符”。这是一个正则表达式，而不是 shell globbing - 具有不同含义的不同元字符。

你可能想要这个：

$6 ~ /^ring..\.cs\.utsa\.edu$/

去掉双引号。

$6 ~ /regex/

不是

$6 ~ "/regex/"
