I have two dozen .csv files, each about a thousand lines long, they've been created with Tie::Array::CSV. Now I want to append a line or two to each of them every day, what's the most efficient way to do that?

I suppose I could read each file into an array, add my data, and write array back to csv again but this means I risk losing all data if something goes wrong during overwrite, and if I create new files I need to figure out some system to automatically manage all those copies of copies that keep piling up every day.

If there's no module to append lines, how to do it manually with all the conventions and escape characters needed for proper csv so that they can be read back into perl without problems?
