Q. How do I know which commands were run by my users on my RHEL / Debian / CentOS / Suse / Fedora Linux server?
A. You need to install package called psacct, which contains several utilities for monitoring process
activities, including ac, lastcomm, accton and sa. The ac command displays statistics about how long users have been logged on. The lastcomm command displays information about previous executed
commands. The accton command turns process accounting on or off. The sa command summarizes information about previously executed commands.

For those needing to log parameters of commands;
There is a package called “snoopy” it wraps “exec” calls and logs any command that has been run, it logs user, command and parameters. It does not log shell builtins like cd and ls, as they do not call exec.
