How do you remove duplicates in source flat files?

Answer 1

To remove duplicates in source flat files, you can use command-line tools like sort and uniq in Unix/Linux environments. First, sort the file using sort filename.txt and then pipe the output to uniq with sort filename.txt | uniq > output.txt, which will create a new file without duplicates. Alternatively, you can use programming languages like Python with libraries like Pandas to read the file, drop duplicates using DataFrame.drop_duplicates(), and then save the cleaned data back to a flat file.
