How to delete lines containing a string in specific column

Question

I have a big CSV file, and I need to delete all rows that contain a certain string ( "linux" ) in the fourth column. Could you advise me how to do it?

试试下面的代码

csv_lines = CSV.read('path/to/file.csv',headers:true).reject{|row| row[3].to_s.include?('linux') }
