The old links didn't point to valid locations.
Replace the old links with the new links and test those changes with a
small script: https://github.com/initBasti/markdown_link_check .
______________________________________________________________
In order to find and replace the links, I used the following commands:
grep -rwohP '.' -e "\(https\:\/\/0xax.gitbooks.io\/\S*\)" > links.txt
(Find all links recursivly in the project directories and print out the
only the matches links)
Within links.txt:
Remove the '(' & ')' => :%s/\(//g and :%s/\)//g
Remove duplicates => :sort u
Test if the links work with:
python3 md_link_check.py --pattern 0xax.gitbook --output-file bad.txt
(https://github.com/initBasti/markdown_link_check)
Create replace commands:
:%s/.*/grep -rl & '.' | xargs sed -i 's#&##g'
Enter replacement URL between the 2nd & 3rd '#'
Execute commands: :w !sh
