Hi,

I wrote some unix command line scripts for piwigo. It enables you to log in and log out, update a piwigo site, update category permissions and generate missing derivatives from command line. Additionally, I wrote scripts that rename all picture files in a folder to a specific pattern, convert videos to MP4 format and create video posters. Hope it helps someone at some time.

For details see https://github.com/pommes-frites/piwigo-scripts

Thanks

Timo
