Sometimes a multi-liner is easier to understand+expand
The ( ) is referred as $1. $_ is the input line. /string/ is short for $_ =~ m/string/
The .= appends the string to $_. It's short for $_ = $_ . string
The perl -p option loops and prints at the end of each cycle. (While the -n option only loops.)
In loop mode the next statement jumps to the next cycle. (Like in awk, that is always in loop mode.)
