Detalhes
refreshLinks.php file is a maintenance script to [re]fill the pagelinks, categorylinks, and imagelinks tables. You should run it if you found that categories are empty or don't show all relevant pages, if "What links here?" doesn't work well, or some other link-related trouble. Additionally this script purges links that point to non-existing pages from the following tables: pagelinks, categorylinks, imagelinks, templatelinks, externallinks, iwlinks, langlinks, redirect, page_props
Usage
php maintenance/scriptName.php instead of php maintenance/run.php scriptName.Basic
php maintenance/run.php refreshLinks [starting_article]
for example, if you want the script to start with the page with id 8 000:
php maintenance/run.php refreshLinks 8000

Como evitar problemas de memória
This script may run into memory issues. To avoid this you may like to set a last page_id to refresh.
php maintenance/run.php refreshLinks --e 1500
To do the next set of page_ids you enter
php maintenance/run.php refreshLinks --e 3000 -- 1500
Just continue until all page ids in your wiki were refreshed.
If you forgot to set a last page_id to refresh and the script runs out of memory simply rerun it with the last output page_id as the article to start at, e.g.
php maintenance/run.php refreshLinks -- 1600
Chunking refreshLinks.php to refresh all links without memory leak
Below is an example script to run refreshLinks.php against all pages but without having memory issues.
num_pages=$(php /path/to/mediawiki/maintenance/showSiteStats.php | grep "Total pages" | sed 's/[^0-9]*//g')
end_id=0
delta=2000
echo "Beginning refreshLinks.php script"
echo " Total pages = $num_pages"
echo " Doing it in $delta-page chunks to avoid memory leak"
while [ "$end_id" -lt "$num_pages" ]; do
start_id=$(($end_id + 1))
end_id=$(($end_id + $delta))
echo "Running refreshLinks.php from $start_id to $end_id"
php /path/to/mediawiki/maintenance/run.php refreshLinks --e "$end_id" -- "$start_id"
done
# Just in case there are more IDs beyond the guess we made with showSiteStats, run
# one more unbounded refreshLinks.php starting at the last ID previously done
start_id=$(($end_id + 1))
echo "Running final refreshLinks.php in case there are more pages beyond $num_pages"
php /path/to/mediawiki/maintenance/run.php refreshLinks "$start_id"
