In some situations, we need to check the mysql uptime. The following command will give you the MySQL version along with the uptime of MySQL process.
# mysqladmin versionExample:
# mysqladmin version mysqladmin Ver 8.42 Distrib 5.5.35, for Linux on x86_64 Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved. .... ....
