You haven't mentioned if you want to change the case as well; I'm assuming you do (as per the output).

Code:
$
$ cat splitrem.pl
#!/usr/bin/perl -w
while (<>) {
  $line = $_;
  print "Input  : ",$line;
  $line =~ s/[[:punct:]]//g;
  $line = lc($line);
  @word = split(' ', $line);
  print "Output : ",join(" ",@word);
  print "\n";
}

$
$ echo "Hello, how are you?" | perl splitrem.pl
Input  : Hello, how are you?
Output : hello how are you
$

HTH,

gpiv_fasty

GPIV_FASTY(1)						      General Commands Manual						     GPIV_FASTY(1)

NAME

       gpiv_fasty - Simple data manipulation tool for PIV data.

SYNOPSIS

       gpiv_fasty [-h | --help] [-p | --print] [-v | --version] [filename] < stdin > stdout

DESCRIPTION

       gpiv_fasty  returns fast running y-positions of data that are originally written with fast running x-positions. All other variables (parti-
       cle displacements, snr, peak#) are at the new positions as well.

       The parameters read from the configuration resources (containing the key POST) may be overruled by the command line options,  as  explained
       below.

Options
       -h | --help
	      On-line help.

       -p | --print
	      Prints  parameters, command line options and input and output filenames to stdout. The output is identic of filename.par, in case -f
	      is used.

       -v | --version
	      Print version information on standard output, then exits successfully.

       filename
	      Input Piv data file. Overrides stdin and stdout. Output will be written to  filename.ma.piv.  The  parameters  will  be  written	or
	      appended to filename.par and may be used for future use by including them in ./gpivrc.
