Sybase BCP date formatter

When using Sybase's "bcp out" to a delimited file, fix the default date format to be something more portable (and sortable). This assumes a pipe delimited file, adding options to change that is left as an exercise. This is a function instead of a standalone script so that it can be included within another program.
BEGIN { my $pgm = <<'EOT'; my @mon = qw( Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec ); my %mons; my $i; $mons{$_} = ++$i for @mon; my $mon_str = join("|", @mon); my $mon_re = qr/$mon_str/; 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("%04d-%02d-%02d %02d:%02d:%02d.%03d", $4, $mons{$2}, $3, ( $9 eq "P" && $5 < 12) ? $5 + 12 : ( $9 eq 'A' && $5 == 12 ) ? 0 +: $5, $6, $7, $8). $10 /eg; EOT sub fix_bcp_file { my ($file) = @_; system($^X, "-pi", "-e", $pgm, $file); } }

    OK, but why run that through system when you can just run it directly in perl:

    { 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 ) = ( '', $file ); while ( <> ) { s/(^|\|)($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( '%04d-%02d-%02d %02d:%02d:%02d.%03d', $4, $mons{ $2 }, $3, ( $9 eq 'P' && $5 < 12) ? $5 + 12 : ( $9 eq 'A' && $5 +== 12 ) ? 0 : $5, $6, $7, $8 ) . $10 /eg; print; # UPDATED thanks runrig } } }
      Being very new to Perl, How is a bcp file called to this script?
        It's not a full script, it's just a function to put into other programs. Call the function with the name of the file to "fix".
