Is there anyway that i can log all the commands that a certain user or user group has run in an ubuntu CLI. I need to keep a track of all the commands run by a certain group of users say
UsrGrp1:usr1,usr2,usr3
as i'm running a Cluster of machines and all are being controlled by different users. And i need to monitor those through the root user of every machine.
The history command gives me all the command logs. But it can be modified by the user itself. So i need to keep the logs under the root user only.
