Hi, i'm new on perl language and i need some help about this: I have a lot of files .csv in differents directories. I need going to each directory and filter each .csv file to a new csv file, what i mean is: for each filter csv file, create a new csv file with the filtered data. And i need it for all the directories. I have to clear that for each directory, the filter string will be different, but I guess that 'll have to change for each directory. I have to use grep command in the perl script. If anybody can help me, i will be very thankfull PD: sorry for my english, but im southamerican :P
