Takes download links from a txt file, makes a folder same as directory name, puts all the downloads in the dir and upon completion put all the files inside zip and save the structure with file size inside a tree.txt. Does this for all txt present in path.

wget.sh

for file in ./* ; do
  dir=$(basename $file .txt)
  mkdir $dir
  cd $dir
  wget -i "../${file}"
  tree -h -D -o "${dir}_tree.txt" .
  zip -r "${dir}.zip" .
  rm *.pdf
  cd ..
  dir=""
done
