请告知如何使用 awk 创建枢轴以形成所需的输出。

【问题讨论】：

欢迎来到 Stack Overflow，请使用代码标签 {} 为您的示例提供不清楚的地方。
无法将问题与 o/p 联系起来。
如果您希望有人帮助您，最好让他们轻松完成。在没有解释的情况下呈现一团难以理解的胡言乱语并不能解决问题。请简化您的示例以使用简短、易于区分的字符串并解释需要什么处理。谢谢。
在这个网站上问了很多次，回答了很多次，随便搜一下就行了。

【解决方案1】：

如果顺序无关紧要，那么

这里是单行：

awk '{k=$1 FS $2; if(!(k in t)){a[$1]=($1 in a? a[$1] RS sprintf("%*s",length($1)+1,"") :"")$2; t[k]}}END{s=sprintf("%0*s\n", length(k),""); gsub(/0/,"-",s); for(i in a)print s i,a[i] }' file

如果你添加 GNU awk，你会得到正确的顺序，

You may try here by pasting given data, in stdin tab

BEGIN{
    PROCINFO["sorted_in"]="@ind_str_asc"
}

更好的可读性：

awk 'BEGIN{
           PROCINFO["sorted_in"]="@ind_str_asc"
     }
     {
        k=$1 FS $2; 
        if(!(k in t))
        {
           a[$1]=($1 in a? a[$1] RS sprintf("%*s",length($1)+1,"") :"")$2; 
           t[k]
        }
     }
  END{
         s=sprintf("%0*s\n", length(k),""); 
         gsub(/0/,"-",s); 
         for(i in a)print s i,a[i] 
     }
    ' file

输入：

$ cat file
