Recursive wget ignoring robots

wget

$ wget -c -m -np -k -p -E -e robots=off 'http://example.com/folder/'
  • -c Continue getting a partially-downloaded file
  • -m This option turns on recursion and time-stamping, sets infinite recursion depth and keeps FTP directory listings. It is currently equivalent to ‘-r -N -l inf --no-remove-listing’
  • -k --convert-links After the download is complete, convert the links in the document to make them suitable for local viewing
  • -p This option causes Wget to download all the files that are necessary to properly display a given HTML page
  • -E cause the suffix ‘.html’ to be appended to the local filename
  • -e robots=off causes it to ignore robots.txt for that domain
  • -r makes it recursive
