[Classiccity-pm] substitutions

[Stephen Howard]

well, since this is a perl list and not a sed list I can't give you any 
sed tips, but you might try something like (untested):

open my $file, '<', $ARGV[0] or die $!;

while( my $line = <$file> ) {
     $line =~ s/\s+/\n/g;
     print $line;
}

and then call it as

perl myscript.pl fileA > fileB

Since there is a space between all email addresses, I thought I could do a simple substitute of the space with a new line.
