I am busy changing the world

I would use the  wp-cli  command line tool to reset timezone of all sites in my WordPress Multisite. For example to GMT+7 wp site list --field=url --allow-root | xargs -n1 -I {} sh -c 'wp --url={} option update gmt_offset 7 --allow-root'

This is the only solution that works for me in reducing the pdf file size: Usage: 1. In the  command line: $ ./compresspdf.sh mypdf.pdf 2. The command opens a GUI interface, select Screen-view only (72dpi) and click OK  3. Beautiful

Quite easy: for filename in /path/to/*.pdf; do convert -density 300 "$filename" "$filename.jpg";done
