You can find this out by reading the perlrun man page (from the command
line, do 'perldoc perlrun'. But briefly:
-w means to turn on warnings about certain runtime problems.
-p means to execute the Perl code once for each line of input.
-i means to modify the files "in place", but...
-i.bak means to back up the files (with the extension .bak) first.
These are incomplete descriptions; again, perlrun has the full details.
