in thread Sybase BCP date formatter

Read perlre and perlop about s/// and the /e switch. This will give you the information you need to find out where the variables $1 to $9 get loaded. Also, you might be interested in the strftime function of the POSIX module, which has convenient functions to create date/time strings. Even moreso, I recommend staying with the given format YYYY-mm-dd HH:MM:SS instead of using something else.

        Ok... I've muddled along here and am getting a bit closer to what I need. 
        #!/usr/bin/perl

use strict;
use warnings;

{   my %mons = qw( Jan 1 Feb 2 Mar 3 Apr 4 May 5 Jun 6 Jul 7 Aug 8 Sep
+ 9 Oct 10 Nov 11 Dec 12 );
    my $mon_str = join '|', keys %mons;
    my $mon_re = qr/$mon_str/;

    sub fix_bcp_file {
        my ( $file ) = @_;
        local ( $^I, @ARGV ) = ( '.bak', $file );
        while ( <> ) {
            s/(^|\,)($mon_re)\s{1,2}(\d{1,2})\s(\d{4})\s\s?(\d\d?):(\d
+\d):(\d\d):(\d{3})([AP])M(\,|$)/
              $1 .
              sprintf( '%02d %02d %04d %02d:%02d%sM',
                $mons{ $2 },
                $3,
                $4,
                $5,
                $6,
                $9 ) .
             $10
            /eg;
            print;  # UPDATED thanks runrig
        }
    }
}
for my $file (@ARGV) {
   fix_bcp_file($file);
}

        So from my test data which is:
        0960280645060099800,1,0,1,03/01/200003240685/0960280645060099800_1,,,,52688,Jan 28 1997 9:53:22:610AM,200003240685
        My script will now convert to:
        0960280645060099800,1,0,1,03/01/200003240685/0960280645060099800_1,,,,52688,01 28 1997 09:53AM,200003240685

        Can someone suggest how I can get rid of leading zero's without creating a space?

          You probably don't even want to use sprintf if you don't want leading zeroes. Just use double quotes. Try this:
          my $x = 1;
my $y = 2;
my $str1 = sprintf "%02d %02d\n", $x, $y;
print "$str1\n";
my $str2 = "$x $y";
print "$str2\n";

          I agree with Corion though, that the date format ought to be YYYY-mm-dd if at all possible. I guess it depends on what you're using the date for...
