# only works for links pointing to files with the ".pdf" extension
#
# USAGE: pdflinkextractor "www.website.com"
WEBSITE="$1"
echo "Getting link list..."
lynx -cache=0 -dump -listonly "$WEBSITE" | grep ".*\.pdf$" | awk '{print $2}' | tee pdflinks.txt

Монтаж
Вам нужно будет иметь wget
и lynx
установить:
sudo apt-get install wget lynx
использование
Сценарий получит список всех .pdf
файлов на веб-сайте и выведет его на выход командной строки и в текстовый файл в рабочем каталоге. Если вы закомментируете «необязательную» wget
команду, скрипт продолжит загрузку всех файлов в новый каталог.
