I use our university's NextCloud instance to host my remote teaching videos. But manually generating all those share links that I need is no fun.

Open the folder with all the videos you want to generate share links for. And execute the script. The script will go through the list and click the share button, then click the generate share link button, the resulting share link is than stored in an array and returned in the end.

The script has a filter to check for specifc extensions only.

NextCloud can be a bit slow at times (at least out instance, so you might need to modify the timeout variable.

You need to scroll once to the end of the page, to load all the data.
