ngos

(EXPERIMENTAL, there are still many bugs)

Tool for comparing two CSV files, and create the output of the difference. Ngos can compare millions of lines of csv file just in second.

TODO:

• Implement Concurrency

Usage

• Build binary from source

$ go get github.com/Bhinneka/ngos

$ go install github.com/Bhinneka/ngos/cmd/ngos

$ ngos -v

$ ngos -old old_file.csv -new new_file.csv -o output.csv

Which is

• old_file.csv

Los Angeles,34°03′N,118°15′W
New York City,40°42′46″N,74°00′21″W
Paris,48°51′24″N,2°21′03″E

• new_file.csv
