In "Effective Perl Programming" (i read this from back to front now because I have read it so many times and keep hitting the same thing) Randal Schwartz offered the above as a way to take a file and join lines together in pairs. perl -pe 's/\n/" " . <>/e' data I have 2 questions about this: 1: what does /e do in a regexp? 2: if data is a filehande and this is a one-liner, how does data get input from a file with "\n"=separated values?
