'service mysql status' returns different values
I have a simple bash script running the following command:
service mysql status | mail -s "MySQL service" firstname.lastname@example.org
I have added it to the crontab of the root user:
sudo crontab -e
Using the following command:
*/1 * * * * bash /home/myname/cron/mysql.sh
And the resulting email contains this:
* /usr/bin/mysqladmin Ver 8.42 Distrib 5.5.37, for debian-linux-gnu on x86_64

UNIX socket /var/run/mysqld/mysqld.sock

These complicated statistics are are not expected value from the 'service mysql status' command.
When I run the batch file manually as root:
sudo bash mysql.sh
The resulting email contains the expected result:
mysql start/running, process 11928
So why is the 'service mysql status' command returning an unexpected value when run from a batch file inside the root cron job?
