How do I run a command on multiple files
This is pretty basic, I have a folder with several subfolders of JS files and i want to run Google’s Clojure compiler on all of the files in those folders. The command to process a single file is as follows:
command-line
grep: input file ‘X’ is also the output

Initialize WordPress environment to use in a real cron script
I have to run a PHP script through real cron (WP cron being too unreliable). Within that script, I need $wpdb to insert data into WordPress table.
