Download a file

Download a file: wget https://0xfab1.net/CNAME -O CNAME Download a list of files wget -i urls.txt -N -e robots=off --user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:86.0) Gecko/20100101 Firefox/86.0"

Download all files from website

Generally, the following can be blocked but works in most cases. There are a few things that can be done to avoid getting blocked:

  • Ignore robots.txt blocking the download by using-e robots=off
  • Add user-agent; either one that guarantees a math e.g.--user-agent="Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36" or just the one you are using atm e.g.--user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:86.0) Gecko/20100101 Firefox/86.0" (Firefox: about:config → devtools.responsive.userAgent)
  • Random service blocks: Try removing some options as they may the reason access is blocked e.g.-N blocked by AWS S3.
  • Adding a referrer may help. Figure out what you need by checking why it works in the browser e.g.wget --referer='http://example.net' http://example.com/
  • Checking the details of the HTTP status code you get as an error may help resolve the issue too: https://en.wikipedia.org/wiki/List_of_HTTP_status_codes
  • A required cookie or missing authorization can be further reasons why the download doesn't work or run though fully.

Example:

wget -e robots=off -r -np --page-requisites --convert-links --user-agent="Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36" http://example.com/dir/

Alternative:

wget -e robots=off --verbose --debug --adjust-extension --backup-converted --base=http://example.com/dir/ --no-http-keep-alive --no-parent --mirror http://example.com/dir/

Download specific files types

wget -e robots=off -r -A ogg,mp3 http://example.com/dir/ # Specific audio files
wget -e robots=off -r -A png,jpeg,jpg,gif http://example.com/dir/ # Specific Image Files
wget -e robots=off -r -l 3 -np -p  http://example.com/dir/ # All pictures

Download features

In case you are downloading clear text files it may come in handy to preview the download:

wget http://0xfab1.net/todo.txt --output-document - | head -n4

Continue a partially downloaded file where the download was interrupted with -c for continue:

wget -c https://0xfab1.net/best-distro2.iso

You can copy an entire web page with --mirror which is the same as adding parameters --recursive --level inf --timestamping --no-remove-listing. When using mirror consider using --no-cookies --page-requisites --convert-links as additional parameters:

wget --mirror --no-cookies --page-requisites --convert-links http://0xfab1.net

Use --debug to view HTTP header information of your download request.

wget --debug https://0xfab1.net

If you want to deal with redirects as error set --max-redirect 0. This is also handy if you don't want to follow URL-shorter links:

wget --max-redirect 0 "https://bit.ly/0xfab1"
