challenge accepted:
grep -f delete -v data.csv > filtered.csv
rm data.csv
mv filtered.csv data.csv
`delete` is the file with the names to delete from the data, and `data.csv` is
just your data to operate on. `filtered.csv` is a temporary file. It can also
be done without a temporary file by using sed instead of grep, but then it
would not be grep anymore.
I don't want to criticise the SQL solution, though.
