update each wordpress plugin with wp-cli and commit each update with plugin name and version in commit message

update-plugins.sh

#!/usr/bin/env bash

wp () {
    command /usr/local/bin/php7.2.11-cli ~/wp-cli/wp-cli.phar "$@"
}

for plugins in $(wp plugin list --path='../html/' --update=available --fields=name,version,update_version --format=csv);
do
    IFS=', ' read -r -a plugin <<< "$plugins"

    if [ ${plugin[0]} = "name" ]; then
        continue
    fi
    wp plugin update ${plugin[0]} --path='../html/' &&
    git add -A ../html/wp-content/plugins/${plugin[0]} &&
    git commit -m "Plugin update - ${plugin[0]} - ${plugin[1]} to ${plugin[2]}"
done;

The script is located in a scripts folder next to the Wordpress installation. That's why the --path option is used.
