Shell commands in HTML?

Spooky · 12-15-2003, 08:25 AM

I need to create a HTML site with some kind of way to execute a normal shell command ... so that i can create another .html file...

Basicaly i need something that reads and creates a HREF link to the files that are present in a dir when i like to have acess to them... i already do this but i have to enter into my shell acount and execute this command :
------------------------------------------------------------------------------------------------
echo "<HTML><BODY>" > index.html; for i in `ls`; do echo "<a HREF="$i">$i</a><br>">> index.html; done; echo "</BODY></HTML>" >> index.html
------------------------------------------------------------------------------------------------

it creates a index.html with all the files in a given dir .

Is it possible? how?

btw: can some one show me some links about HOWTO PHP or something like that ... PHP tutorials... etc.

Thanks
Spooky

You wouldn't be able to do this with HTML alone. You will need some sort of server-side scripting language, such as PHP, or a CGI app. Take a look at http://www.php.net for some good PHP references.

The best way to learn PHP is reading a book. You will find there all basics and some advanced topics and many examples, which will certainly help you.

And about my "index" problem how can i do it in php?

Here's a PHP script I use to show a list of all JPG files in a directory. It assumes that directories have no "." in them, and that anything w/o a "." in it is a directory, (I was too lazy to lookup how to check for the file attributes in PHP at the time I wrote this. ) but it should serve as an example:

Code:

<?
$dir = opendir("./");
$filelist = array();
$dirlist = array();

while ($file = readdir($dir))
{
        if (strchr($file, ".jpg") !== false ||
                strchr($file, ".JPG") !== false)
        {
                array_push($filelist, $file);
        }
        else if (strchr($file, ".") === false)
        {
                array_push($dirlist, $file);
        }
}

sort($filelist);
reset($filelist);

sort($dirlist);


?>

<table border=0; cellspacing=0;cellpadding=0>
<?
while(list($index, $dir) = each($dirlist))
{
        $link = "$dir/";
        ?>
        <tr><td><a href="<?=$link?>"><?=$dir?></a></td></tr>
        <?
}

while(list($index, $file) = each($filelist))
{
        $link = "$file";
        ?>
        <tr><td><a href="<?=$link?>"><?=$file?></a></td></tr>
        <?
}
?>
</table>

Nice... but for example... how does that example work?... where do i place it to work?... and can i make it work in a dinamic button or something like that... can't i make for example this command work " ln -s ... " and then make it show the dir?

I have to learn more of PHP and how it works to start doing stuff like that on my own... but i guess it's a start...

thanks for the help

When you want to run it from web you need Apache and PHP to be installed.
Then you place your myscript.php file into "DocumentRoot" directory. Then you can call it: http://localhost/myscript.php in your browser.

Yes, you need to have a PHP module installed. My example code is saved into a file called index.php. And when you view it, it gives you a list of the files. It was something I put together quickly because I wanted to show some people a bunch of digital photos I had taken, but I didn't want to allow directory browsing under Apache. I keep meaning to expand it somewhat and make it check/display various file attributes, but I've been too lazy to do that.

i change it to show ALL the files in this dir...

$dir = opendir("../temp");
$filelist = array();
$dirlist = array();

while ($file = readdir($dir))
{
if (strchr($file, ".") !== false)
{
array_push($filelist, $file);
}
else array_push($dirlist, $file);
}

ok... this is about showing what we have in a given dir but for instance can we execute the command like ... " ln -s ../dir/* ./ " to create the symbolic links and let's say chmod commands? or we realy have to enter the shell and execute them?
