Linux计算文件内某个字段的和
有以下文件 Prepaid.log
"20200705","極光","974.10","4","1","10990778","23","0","","72"
"20200705","極光","1064.10","4","1","10990780","24","0","","72"
"20200705","★慕瑤★""57928.20","11","1","10990785","108","0","","72"
想要统计第3个字段的和：974.10+1064.10+57928.20 ，可以使用以下命令，多个文件可以使用通配符
cat */*/Prepaid.log | awk -F '","' '{sum += $3};END {print sum}'
-F '","' 表示以 "," 为分割符
“20200705”,“極光”,“974.10”,“4”,“1”,“10990778”,“23”,“0”,"",“72”
会分为以下数组
- "20200705
- 極光
- 974.10
- 4
- 1
- 10990778
- 23
- 72"
然后求和输出即可
