How can I keep .csv line data that only contains the words
cat and only check for them on the second column, if the word "dog" appears on any other column but not the 2nd then it should be ignored.
For example if I had:
email1.com dog email2dog.com steve email3.com cat
email1.com dog email3.com cat
There maybe a long list of words to keep so if possible load them from another file.
