Hi, i am new in perl.
I am trying to write a simple script to show an index.html.
however it works only 40%! only one item is shown in the index.html... can u please guide me step-by step? thanks in advance!
Code: 
#!/usr/bin/perl

$httrackpath = "/usr/local/bin";
$websites="/data/websites";


opendir(DIR, $websites);
@files=readdir(DIR);
closedir(DIR);

for $file(@files) {
        ## List all files and directories from /data/websites ##
        next if ($file =~ /^\./); # Ignore anything start with dot "."
        next if (!-d "$websites/$file");  # Ignore if it is not a directory
        next if ($file =~ /hts-cache/); # Ignore if it is hts-cache dir
        print "[$file]\n";

        open(HTML, ">/root/index.html");



    print HTML "<html>\n<head>\n<title>$base$i</title>\n</head>\n<body>\n";
    print HTML "<a href=\"$base$next.html\"><img src=\"$base$i.jpg\"></a>\n";
    print HTML "</body>\n</html>\n";

    print HTML "<&middot; <A HREF=\"$file/index.html\">$file</A>";
    close(HTML);



        ## proceed with the next function ##

        ## End, next website ##
}

Hi

You are creating the /root/index.html again and again, each time the loop is executed. So each time the previous file will be overwritten and finally you will have the last created one.

Just move the [tt]open[/tt] and [tt]close[/tt] together with the [tt]print[/tt]ing of common parts out from the loop :
Code: 
[gray]#!/usr/bin/perl[/gray]

[navy]$websites[/navy][teal]=[/teal][green][i]"/data/websites"[/i][/green][teal];[/teal]

[b]opendir[/b][teal]([/teal]DIR[teal],[/teal] [navy]$websites[/navy][teal]);[/teal]
[navy]@files[/navy][teal]=[/teal][b]readdir[/b][teal]([/teal]DIR[teal]);[/teal]
[b]closedir[/b][teal]([/teal]DIR[teal]);[/teal]

[highlight][b]open[/b][teal]([/teal]HTML[teal],[/teal] [green][i]">/root/index.html"[/i][/green][teal]);[/teal][/highlight]

[highlight][b]print[/b] HTML [green][i]"<html>\n<head>\n<title>$base$i</title>\n</head>\n<body>\n"[/i][/green][teal];[/teal][/highlight]

[b]for[/b] [navy]$file[/navy][teal]([/teal][navy]@files[/navy][teal])[/teal] [teal]{[/teal]
    [gray][tt] List all files and directories from /data/websites [/tt][/gray]
    [b]next[/b] [b]if[/b] [teal]([/teal][navy]$file[/navy] [teal]=~[/teal] [green][i]/^\./[/i][/green][teal]);[/teal] [gray]# Ignore anything start with dot "."[/gray]
    [b]next[/b] [b]if[/b] [teal](!-[/teal]d [green][i]"$websites/$file"[/i][/green][teal]);[/teal]  [gray]# Ignore if it is not a directory[/gray]
    [b]next[/b] [b]if[/b] [teal]([/teal][navy]$file[/navy] [teal]=~[/teal] [green][i]/hts-cache/[/i][/green][teal]);[/teal] [gray]# Ignore if it is hts-cache dir[/gray]
    [b]print[/b] [green][i]"[$file]\n"[/i][/green][teal];[/teal]

    [b]print[/b] HTML [green][i]"<a href=\"$base$next.html\"><img src=\"$base$i.jpg\"></a>\n"[/i][/green][teal];[/teal]

    [gray][tt] proceed with the next function [/tt][/gray]

    [gray][tt] End, next website [/tt][/gray]
[teal]}[/teal]

[highlight][b]print[/b] HTML [green][i]"</body>\n</html>\n"[/i][/green][teal];[/teal][/highlight]
[highlight][b]print[/b] HTML [green][i]"<&middot; <A HREF=\"$file/index.html\">$file</A>"[/i][/green][teal];[/teal][/highlight]

[highlight][b]close[/b][teal]([/teal]HTML[teal]);[/teal][/highlight]

I have to wonder why you want to create the file "index.html" when you could just have your script as CGI dynamically generate it every time the page is requested.

Good question, but I can imagine some reasons :
[ul]
[li]Exactly for that : to generate it once, instead of every time.[/li]
[li]To have a static file available during scheduled maintenance of the site.[/li]
[li]To include it in documentation shipped on CD/together with an application.[/li]
[li]To use it as input for an application which does not handle HTTP itself.[/li]
[/ul]
I skipped the obvious reasons.

Hi

I would not put it in the generated index.html. Better put that CSS ( without the HTML tags and comments ) into a separate file, let us say, style.css, then in the script :
Code: 
[b]print[/b] HTML [green][i]"<html>\n<head>\n<title>List of available projects - HTTrack Website Copier</title>\n[highlight]<link rel=\"stylesheet\" type=\"text/css\" href=\"style.css\">\n[/highlight]</head>\n"[/i][/green][teal];[/teal]

Assuming the perl script is in the cgi-bin, and the style-sheet is in the web root ( if it isn't you may have to move it there), you should make the path to the style sheet relative to the cgi-bin using ../ in the URI:

Code: 
<link rel=\"stylesheet\" type=\"text/css\" href=\"../style.css\">\n

the cgi-bin may block a request for something like a style sheet document because most cgi-bins are setup to only respond to requests for scripts and not any other type of document.
