Here's my script to download IBM javadocs:
(
rm -rf wget-test
mkdir wget-test
cd wget-test
starturl="http://www-01.ibm.com/support/knowledgecenter/api/content/SSZLC2_7.0.0/com.ibm.commerce.api.doc/allclasses-noframe.html"
wget -d -r -R robots.txt --page-requisites -nH --cut-dirs=5 --no-parent
"$starturl" 2>&1 | tee wget.log
)
regardless of '-R' option, wget downloads robots.txt and refuses to
follow links starting with "/support/knowledgecenter/api/".
Workaround:
touch robots.txt
chmod 400 robots.txt
GNU Wget 1.15 built on linux-gnu
