Thanks to all. I tried to use the suggested solutions, but it seems I have not well specified what I meant: the words included in @filter must match when they're not embedded in other words... Using the code above, when @filter meets a phrase in @main that contains, for example, "Ethernet", it strips out "the" and it returns "Ernet" , and that's not what I meant... Sorry if I was unclear.. I tried anyway to do : 
for $filter (@filters) { 
     s/\Q\b$filter\b\E//ig for @main; 
}

adding the \b bound delimiter, but still it doesn't work. How should I improve the regex to obtain what I need? Thank you again.
