Add Total of an Multidimensional Array

Question

Question

I have the following array:

scansum[key,key2]++

key = multiple 6 digit numbers eg. 123456, 234567, 345678 etc.

key2 = a hour eg. 00, 01, 02 etc.

Sample Code

#!/bin/sh

awk '
BEGIN {
        printf ("---------------------------------------\n-----CTS_DR Read Report By Scanner-----\n---------------------------------------\n")
        }
                {
                key = substr ($16,3,6) #Scanner
                key2 = substr ($2,1,3) #Hour
                scanner[key]++
                if ($21 ~ /SR1/) scansum[key,key2]++
                }
END {
                for (scan in scanner) {
                        printf ("\nScanner: MS%6s\tTotal Reads:%8s\n",scan,scanner[scan])
                        for (i = 0; i <= 23; i++) {
                                        if (i < 10)
                                        h = "0" i
                                        else
                                        h = i
                                print "Hour: "h " Count Test: "scansum[scan,h]
                                }
                        }
}'

I know that for a normal array you can just do:

for (alias in arrayname) {
print arrayname[alias]
}

and this will do a count of the array split by the key but for a multidimensional array the following doesn't seem to work:

for (alias in arrayname) {
  print alias
  for (i = 0; i <= 23; i++) {
      if (i <10)
      h = "0" i
      else
      h = i
  print h"\t"arraynamecount[alias,h]
  }
}

Note

I know that this is missing the setting of the array

I know I am missing something but I can't for the life of me see what it is. Any hints/ help for this would be greatly appreciated.

如this link中所述，您可以使用split()函数为awk多维数组的每个索引获取一个数组，因为表单的每个索引都是

key1,key2,···,keyN

存储为字符串

key1[SUBSEP]key2[SUBSEP]···[SUBSEP]keyN

其中[SUBSEP]代表 SUBSEP 变量中的ASCII字符保留，默认情况下为\034。实际上，您可以使用该字符串访问任何多维数组元素：

x=myarray[key1 SUBSEP key2]

基本上END块看起来应与此类似

END {
      for (scan in scansum) {
        split(scan,ind,SUBSEP)
        print "Scanner: " ind[1] "\tHour: " ind[2] "\tCount Test: " scansum[ind[1],ind[2]]
      }
}
