One way:
Code:
#!/usr/bin/perl
use warnings;
use strict;

my $str1 = "41148,,,,,,,,,,,,,,,,,,,,,,,,";
my $date = "TUE 08-28-2012";

print "Before : $str1\n";
my @temp = split /,/, $str1, -1;
shift @temp;
$str1 = join ",", $date, @temp;
print "After  : $str1\n";

producing
Code:
Before : 41148,,,,,,,,,,,,,,,,,,,,,,,,
After  : TUE 08-28-2012,,,,,,,,,,,,,,,,,,,,,,,,

--------

And with a regexp:
Code:
#!/usr/bin/perl
use warnings;
use strict;

my $str1 = "41148,,,,,,,,,,,,,,,,,,,,,,,,";
my $date = "TUE 08-28-2012";

print "Before : $str1\n";
$str1 =~ s/\A.*?,/$date,/;
print "After  : $str1\n";
