Dear Monks,

Please could somebody explain in detail what the following does? It seems to be a peculiar structure with regard to use of space (or not). What is the xx.pm for? What is -pi.bak? What is xx.pm? I really don't understand any of it. 


Tmp>perl -pi.bak -we"s{Text::CSV}{Text::CSV_XS}g" xx.pm
