It needs if you don't want to waste time to enable Shell Access for specific user to run some command from his shell
sudo -H -u someuser bash -c 'uptime'
Example of using:
cd ~someuser/www
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar chmod +x wp-cli.phar mv wp-cli.phar wp
sudo -H -u someuser bash -c './wp plugin status'
or
sudo -H -u `pwd |cut -d/ -f3` bash -c './wp plugin status'
It will show a status of installed WP plugins for this user using wp-cli tool
