wgetis a great tool to download files or webpages. It is not the first timke that I find that the links of a webpage are not updated or wrong. For instance, a web page which has its pictures/files linked with http://websitehttp//website.file.extension. Is there a way to tell wget that, if no content is found, it has to look in the address http//website.file.extension instead of http://websitehttp//website.file.extension?

EDIT: Following @Tigger's comment, I can get exit status but how to ask wget for that specific file that failed to get it on the right link/address?

wget_output=$(wget –limit-rate=200k –no-clobber –convert-links –random-wait -r -p -E "$URL")
if [ $? -ne 0 ]; then
  • 1
    wget will exit 0 if there are no errors and from 1 to 8 on another kind of error (see exit status in man page). You could use the exit status within a simply shell script to work out when to try a second link. – Tigger Dec 6 '16 at 22:08

Here is a simple script that might help you to get started:


# Make sure a URL is passed first
if [ -z "$1" ]
    echo "
Pass the full URL to be downloaded. For example:

 ${0##*/} \"http://websitehttp/website.file.extension\"

If that URL fails, then \"http://website.file.extension\"
will be tried automatically.
    exit 1

# Attempt download
wget -v "${1}"

# Check for an error and if so, try an alternative download
if [ "$?" != "0" ]
    url2=`echo ${1} | cut -d '/' -f 4-`
    # DEBUG echo "[$url2]"
    wget -v "http://${url2}"

echo "Done"
exit 0

  • thanks again. I have tested the script but please note that I am doing a recursive call to an url and therefore I do not know in advance the complete link address of the different webpages. I only know that some links are wrong because the parent "www.website.com" is duplicated in the link to some files in some webpages. – nopeva Dec 6 '16 at 23:44
  • If you are doing a recursive crawl and the links are wrong then there is very little you can do. My understanding is wget can not guess what the correct link should have been :] One option might be to create a wget log file and then parse the errors in the log file (using a script). – Tigger Dec 7 '16 at 0:13
