Hello all. I am new to programming in Perl and I was wondering if I could get some advice. I would like to create a script that will dynamicly present in HTML and index of my files. These "files" would of course be href links. I am trying to put my family photos on the web and can host at home for I have static IP... so...

I would think that I am going to need to write out a temp file/pipe with the fully qualified filename paths, read it into a loop and create/print the html link.

I am shure there is a relatively easy way to do this! Thanks!

Don't even both with temp files. You can just get the directory contents in perl and create links from them, then print the output to the browser. If you have CGI turned on, something like this would work (find all JPG files in BASEDIR, and print a list with all the links):

Code:
#!/usr/bin/perl

use warnings;
use strict;

my $BASEDIR = "/var/www/htm/images";

sub file_to_link {
  my $file = shift;
  my $link;
   #write some code to change a path listing into a link
  return $link;
}

my @files = split("\n", `find $BAREDIR -type f -name '*.jpg'`);

print "Content-type: text/html\n";
print "\n";

print "<html>\n<body>\n<ul>\n";

foreach my $file (@files) {
  my $link = file_to_link($file);
  print "<li>$link</li>\n";

print "</ul>\n</body>\n</html>\n";


Good luck.

thanks for the great info. What variable will I be using as the full path to the file? I can get teh HTML code to call a file link, just do not know what the var is!!!

I find perl to be very difficult to understand. I am coming from a VMS background where things make sense to me...

In the sample code I wrote, $file is the path to the file, from the place the find started (/var/www/htm/images). So...

"/var/www/html/images/" . $file

would be the absolute path.
