上面一个文件 1.txt

Fan   0 0 1
Gong  0 1 0
Tian  0 1 1
Long  1 0 0
Zhang 1 0 1
Dai   1 1 0
Jin   1 1 1

下面是脚本

BEGIN {
#     RS = ";"
#     FS = ")"
      printf (" Generated at --- ")
      system("date")
      printf (" ");
      max = 0
      date = 2;
}

{#get date and initial total
      if ($0 ~ /Name/)
            for(x=2; x<=NF; x++) {
                  total[x, 2] = "They are: "
                  total[x, 1] = 0 #number of ava members
                  total[x, 0] = $x #invitation date
           }
}

{     if($0 ~ /Jin/) next } #ignore host Mr.Jin

{
      for ( x = 2; x <= NF; x++)
            if($x == 1) {
                  total[x, 1] = total[x, 1] + 1
                  total[x, 2] = sprintf("%s %s",total[x, 2], $1)
                  #printf ("total[%d] = %d ",x,total[x,1])
                  if(total[x, 1] > max) {
                        date = x;
                        max = total[x, 1]
                  }
                  else if ((total[x, 1] == max) && (date > x))
                        date = x
           }
}

END {
      #print max, date
      if(max == 0)
            print "Disappointed result: I am afraid that King's second invitation is to be canceled again! "
      else {
            print "The earliest day of  June,18th is your choice to invite the most classmates in Shanhai!"
            print total[date, 2]
      }
}

运行时，用

awk -f 1.awk 1.txt
