I need help in extracting specific data from log files. The log file has 51 fields I only need 11 fields from that file. I need to "open" to a new file output with only the data from the 11 fields. The new file will be specific to the customers. I have 10-20 customers in each log file I need to create a new log file per customer with only the pertinent data. Here is what I have so for, any suggestions or help with this is thoroughly appreciated. Jeff Stout
