在bash文件的每一行中添加一個數字

Question

我在Linux中有一些帶有某些行的文件，例如：

2013/08/16,name1,,5000,8761,09:00,09:30
2013/08/16,name1,,5000,9763,10:00,10:30
2013/08/16,name1,,5000,8866,11:00,11:30
2013/08/16,name1,,5000,5768,12:00,12:30
2013/08/16,name1,,5000,11764,13:00,13:30
2013/08/16,name2,,5000,2765,14:00,14:30
2013/08/16,name2,,5000,4765,15:00,15:30
2013/08/16,name2,,5000,6765,16:00,16:30
2013/08/16,name2,,5000,12765,17:00,17:30
2013/08/16,name2,,5000,25665,18:00,18:30
2013/08/16,name2,,5000,45765,09:00,10:30
2013/08/17,name1,,5000,33765,10:00,11:30
2013/08/17,name1,,5000,1765,11:00,12:30
2013/08/17,name1,,5000,34765,12:00,13:30
2013/08/17,name1,,5000,12765,13:00,14:30
2013/08/17,name2,,5000,1765,14:00,15:30
2013/08/17,name2,,5000,3765,15:00,16:30
2013/08/17,name2,,5000,7765,16:00,17:30

我列分隔符為“ ”並且在第三列（目前, ,, ），我需要在同一天內的條目號。 例如，日期為2013/08/16的我有11行，日期為2013/08/17的我有7行，因此我需要添加數字，例如：

2013/08/16,name1,1,5000,8761,09:00,09:30
2013/08/16,name1,2,5000,9763,10:00,10:30
2013/08/16,name1,3,5000,8866,11:00,11:30
2013/08/16,name1,4,5000,5768,12:00,12:30
2013/08/16,name1,5,5000,11764,13:00,13:30
2013/08/16,name2,6,5000,2765,14:00,14:30
2013/08/16,name2,7,5000,4765,15:00,15:30
2013/08/16,name2,8,5000,6765,16:00,16:30
2013/08/16,name2,9,5000,12765,17:00,17:30
2013/08/16,name2,10,5000,25665,18:00,18:30
2013/08/16,name2,11,5000,45765,09:00,10:30
2013/08/17,name1,1,5000,33765,10:00,11:30
2013/08/17,name1,2,5000,1765,11:00,12:30
2013/08/17,name1,3,5000,34765,12:00,13:30
2013/08/17,name1,4,5000,12765,13:00,14:30
2013/08/17,name2,5,5000,1765,14:00,15:30
2013/08/17,name2,6,5000,3765,15:00,16:30
2013/08/17,name2,7,5000,7765,16:00,17:30

我需要用bash來做。 我該怎么做？

Answer 1

這也很好：

awk -F, 'sub(/,,/, ","++a[$1]",")1' file

輸出：

2013/08/16,name1,1,5000,8761,09:00,09:30
2013/08/16,name1,2,5000,9763,10:00,10:30
2013/08/16,name1,3,5000,8866,11:00,11:30

2013/08/16,name1,5,5000,11764,13:00,13:30
