Help summing a file using awk
I'm trying to sum a text file using AWK. Here is an example of the file:

Code:
600|3H68|        46
600|3H69|        46
600|3H6F|       290
600|3H6G|        24
600|3HDY|         1
600|3HDY|         3
600|3HE0|         1
600|3HE0|         3

I would like to sum the third field if the first two fields are the same.

For example, the last 2 lines, I would like them to sum up and have
600|3HE0| 4

Is this possible using AWK?

I tried something like this, but it gave strange results:
Code:
awk 'BEGIN { FS = "|" } ; '{ arr[$1 "|" $2] += $3 } END {for (i in arr) {print i "|" arr[i] } }' count_all.txt

I appreciate any help you can provide.

Remove the quote after semicolon
Code:
$ awk 'BEGIN { FS = "|" } ; { arr[$1 "|" $2] += $3 } END {for (i in arr) {print i "|" arr[i] } }' file
600|3H68|46
600|3H6F|290
600|3H69|46
600|3H6G|24
600|3HE0|4
600|3HDY|4

Thanks for your reply.

When I try your code, I get the following:

Code:
awk: syntax error near line 1
awk: bailing out near line 1

Here is my exact code that I tried:

Code:
awk 'BEGIN { FS = "|" } ; { arr[$1 "|" $2] += $3 } END {for (i in arr) {print i "|" arr[i] } }' count_sort.txt

Can't seem to find the syntax error.

Thanks again

Use nawk on solaris.

Ok, new twist. The input file format has changed and no longer has delimiters in it. Here is an example.

Code:
9652013010129KM         1
9652013010129KM         4
9652013010129KN         4
9652013010129KO         1
9652013010129KO         4
9652013010129KP         1
9652013010129KP         4

I tried to use the FIELDWIDTHS parameter in nawk to specifiy my columns, but it isn't working quite right. Here is what I tried:

Code:
nawk 'BEGIN { FIELDWIDTHS = "3 8 4 10" } ; { arr[$1 $2 $3] += $4 } END {for (i in arr) {print i arr[i] } }' count_sort.txt > count_sum.txt

It doesn't seem to be adding up the 4th column. based on the first 3 being equal. Also, is there a way to keep the leading spaces in the 4th column on the output?

Thanks again for all your help.

Use printf formatting. Here is an example:
Code:
awk '
{
        A[$1] += $2
} END {
        for (i in A)
                printf "%s%11s%8s%10s\n", substr(i, 1, 3), substr(i, 4, 8), substr(i, 12, 4), A[i]
}' file

Change the spacing as per your requirement.
