$\      The output record separator for the print  operator.
             Ordinarily  the print operator simply prints out the
             comma separated fields you specify, with no trailing
             newline  or  record  separator assumed.  In order to
             get behavior more like awk, set this variable as you
             would  set  awk's  ORS  variable  to specify what is
             printed at the end of the print.  (Mnemonic: you set
             $\  instead  of  adding  \n at the end of the print.
             Also, it's just like /, but it's what you get "back"
             from perl.)
