How to Download an HTML Manual or Book Using wget
I wanted a local copy of the R-Spatial Book to read while I was up at camp. I was going to write an R script to do this but I realize I simple wget with the right parameters, inspired by this StackOverflow answer will do the trick.
wget --recursive ${comment# self-explanatory} \
--no-parent ${comment# will not crawl links in folders above the base of the URL} \
--convert-links ${comment# convert links with the domain name to relative and uncrawled to absolute} \
--random-wait --wait 3 --no-http-keep-alive ${comment# do not get banned} \
--no-host-directories ${comment# do not create folders with the domain name} \
--execute robots=off --user-agent=Mozilla/5.0 ${comment# I AM A HUMAN!!!} \
--level=inf --accept '*' ${comment# do not limit to 5 levels or common file formats} \
--reject="index.html*" ${comment# use this option if you need an exact mirror} \
--cut-dirs=0 ${comment# replace 0 with the number of folders in the path, 0 for the whole domain} \
