感谢大家抽出时间并提出建议。现在我已经到达了我需要获取报告的地方，该报告将在每小时内计算每个文档的每个消费者。

我想出了这个逻辑，首先在 awk 数组中获取小时、文档、消费者，然后每小时获取文档，然后为该文档获取消费者和同一消费者的计数，然后是 avg_rtime。

这是我的输入日志文件。

document| consumer| hour| rtime|    
cust_CreateDocument OLS 23 670
cust_GetDocumentContentStream LDS 14 685
cust_CreateDocument OLS 17 767
cust_GetDocumentContentStream LDS 15 1186
cust_DumpDocumentProperties OLS 15 928
cust_GetDocumentContentStream CPI  0 462
cust_GetDocumentContentStream CPI 0 1338
cust_GetDocument LDS 11 413
cust_GetDocumentContentStream LDS  0 1527  
cust_GetDocumentContentStream LDS  0  473

以下格式的必需输出。 

Hour | document| consumer |count| avg_of_rtime|  
0 cust_GetDocumentContentStream LDS 2 1000=(1525+473)/2#How to compute avg_rtime   
0 cust_GetDocumentContentStream CPI 2  900=(462+1338)/2   
14 cust_GetDocumentContentStream LDS 1 685=(685/1)

这应该有效：

awk '
NR>1 {
    a[$3" "$1" "$2]+=$4
    b[$3" "$1" "$2]++
}
END {
    print "Hour | document| consumer |count| avg_of_rtime";
    for (x in a) {
        print x,b[x], a[x]/b[x] | "sort -nk1"
    }
}' input.log

测试：

$ cat input.log 
document| consumer| hour| rtime|    
cust_CreateDocument OLS 23 670
cust_GetDocumentContentStream LDS 14 685
cust_CreateDocument OLS 17 767
cust_GetDocumentContentStream LDS 15 1186
cust_DumpDocumentProperties OLS 15 928
cust_GetDocumentContentStream CPI  0 462
cust_GetDocumentContentStream CPI 0 1338
cust_GetDocument LDS 11 413
cust_GetDocumentContentStream LDS  0 1527  
cust_GetDocumentContentStream LDS  0  473

$ awk '
    NR>1 {
        a[$3" "$1" "$2]+=$4
        b[$3" "$1" "$2]++
    }
    END {
        print "Hour | document| consumer |count| avg_of_rtime";
        for (x in a) {
            print x,b[x], a[x]/b[x] | "sort -nk1"
        }
    }' input.log
Hour | document| consumer |count| avg_of_rtime
0 cust_GetDocumentContentStream CPI 2 900
0 cust_GetDocumentContentStream LDS 2 1000
11 cust_GetDocument LDS 1 413
14 cust_GetDocumentContentStream LDS 1 685
15 cust_DumpDocumentProperties OLS 1 928
15 cust_GetDocumentContentStream LDS 1 1186
17 cust_CreateDocument OLS 1 767
23 cust_CreateDocument OLS 1 670
