Download database pdf files:
wget -F -np -r -l 2 -nd -nv -nc nH -i a.html
Since the pdf files downloaded are not with .pdf suffix,
have to find the pattern and rename to pdf.
In this case it is with the pattern
"ste=5&docNum=A12345678$"

for i in $(grep 'ste=5&docNum=.[0-9]\{7,\}$' ./files)
do
a=`echo $i | cut -d= -f5`
echo $a
cp $i $a.pdf
done
