How to download multiple files using wget?

Question

Guys, I need to download all images from a folder on a server!

I mean, there’s a website www.tarararara.com/images

And there are 50 images! How do I download these images and put them in a folder of my server using the command wget?

And I need to download all the images from the site, to put in the folder images localhost!

Any way to create a loop? Or something like?

Answer 1

wget -nd -r -P /onde.vc.quer.salvar -A jpeg,jpg,bmp,gif,png http://odominio/imagem

• The -np prevents recursiveness from being used toward the directory Father, if you don’t put that he’ll try to do download of all the images that are on the website.
• The -r allows recursiveness to the children directory.
• The -P will create a directory where will be placed all images.
• The -A indicates all type of file you want.

The possibilities are great and the manual explains very well everything he can do:

Answer 2

The syntax to do this with the wget the Marcos Célio already answered, how the question is marked with the tag php, the answer is based on that language, you can try the following:

1. Download the contents of the com page file_get_contents or cURL, or other way you know.
2. Extract the links page, you can use the function preg_match or parse HTML with DOMDocument.
3. Download the file from a URL, you can use the file_put_contents or cURL together with the function fopen to open the file for writing.

Do the following:

1. To download the content of the page, with cURL:

   function obterPagina($url) {
       $curl = curl_init();
       curl_setopt($curl, CURLOPT_URL, $url);
       curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
   
       return curl_exec($curl);
   }
   

   _{Note: You can include more options depending on the need. More information.}

2. To extract the links of the page, with DOMDocument:

   function obterLinks($url, $pagina, $extensoes = ['gif', 'jpg']) { // Extensões aceitas
       $dom = new DOMDocument;
       $links = [];
   
       if ($dom->loadHTML($pagina) !== false) {
           foreach ($dom->getElementsByTagName('a') as $link) { // Percorre todos os elementos com a tag "a"
               $href = $link->getAttribute('href');
               $extensao = pathinfo($href, PATHINFO_EXTENSION);
   
               if (in_array($extensao, $extensoes)) {
                   $links[] = $url . $href;
               }
           }
           return $links;
       }
       return false;
   }
   

3. To download the file, also with cURL:

   function baixarArquivo($url, $salvarComo, $timeout = 3600) {
       $curl = curl_init(); 
       $fp = fopen($salvarComo, 'w'); // Abre o arquivo para escrita
   
       if (!$fp)
           return false;
   
       $opts = array(CURLOPT_URL     => $url,
                     CURLOPT_FILE    => $fp,
                     CURLOPT_TIMEOUT => $timeout); // Define o timeout, o padrão é 1 hora
   
       curl_setopt_array($curl, $opts);
   
       $ret = curl_exec($curl);
       curl_close($curl);
       fclose($fp);
   
       return $ret !== false;
   }
   

To use, do so:

$url = "http://www.tarararara.com/images/";
$pagina = obterPagina($url);

if ($pagina) {
    $links  = obterLinks($url, $pagina);

    if ($links) {
        foreach ($links as $link) {
            var_dump( baixarArquivo($link, basename($link)) ); // Salva na mesma pasta do script
        }
    }
}
