I have a bunch of files in a directory
 eg. Filename120398101203.doc
     Filename121098150934.doc
     Filenamemmddyyhhmmss.doc
     ....etc

I need to write a program that can automatically grab the a filename and parse it into the correct format.

eg.   #      DATE           TIME
      1      12/03/98       10:12:03
      2      12/10/98       15:09:34
      3      mm/dd/yy       hh:mm:ss

Then spit this information onto an HTML page.

I assume you want to use the filename, rather than it's time stamp.. This should show you how....

#!/usr/bin/perl -w

use strict;

$| = 1;
$base = "/home/asdf"; # or wherever the files are


print "Content-type: text/html\n\n";
print "<HTML>\n";
opendir(DIR,$base) || die "Unable to open dir $base: $!\n";

my(@Files) = grep {-f "$base/$_"} readdir(DIR);
my($i) = 1;
my($date, $time);

print <<EOText;
<br>
<P ALIGN = "CENTER"><CENTER>
<TABLE BORDER CELLSPACING=1 BORDERCOLOR="#000000">
<TR>
<TD BGCOLOR="#000000"><P ALIGN="CENTER"><B>#</B></TD>
<TD BGCOLOR="#000000"><P ALIGN="CENTER"><B>Date</B></TD>
<TD BGCOLOR="#000000"><P ALIGN="CENTER"><B>Time</B></TD>
</TR>
EOText

foreach (@files) {
    m/^(.{2})(.{2})(.{2})(.{2})(.{2})(.{2})/;
   $date = "$1/$2/$3";
   $time = "$4:$5:$6";
   print <<EOText;
<TR>
<TD><P ALIGN="CENTER">$i</TD>
<TD><P ALIGN="CENTER">$date</TD>
<TD><P ALIGN="CENTER">$time</TD>
</TR>

EOText;
}

print "</TABLE></CENTER></P></HTML>";
