Mass change timezone of all sites in WordPress Multisite

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'

A great moment


Compress PDF file

This is the only solution that works for me in reducing the pdf file size:


1. In the  command line:

$ ./ mypdf.pdf

2. The command opens a GUI interface, select Screen-view only (72dpi) and click OK

3. Beautiful

Convert multiple PDF files to JPG in Ubuntu

Quite easy:

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