Linux - Delete lines with duplicate data

If for example you dont want the same email address to be in your .csv files you would run the following command to
awk '!x[$2]++' FS="," FILENAME.csv > newname.csv

FILENAME.csv needs to be replaced with your .csv file and [$2] needs to be edited to represent the line you want to check for duplicate content.
