Automating WordPress updates with cron and the wp-cli

Ain’t nobody got time to worry about updates. I’d rather have it break while updating than have it hacked by a script kiddie because I’ve neglected to login for a while. We will see if this ever breaks anything.

Install WordPress-CLI if you have not already.

Add all your sites to the update_wp.sh script:

#!/bin/bash
declare -a arr=(
  "anthonypenner.com" 
  "trekcamp.org"
  "etc"
)

for i in "${arr[@]}"
do
  echo $i
  cd /usr/share/nginx/html/$i
  sudo -u nobody wp core update
done

NOTE: Substitute /usr/share/nginx/html for the directory that holds your WordPress sites. Change user nobody to the user that owns the aforementioned directories. Check with ls -al, it might be the user that apache/nginx runs as, check that with top, htop, or ps -aux

Make sure it’s executable:

chmod +x update_wp.sh

Run the script daily and live dangerously!
