By default, the ps command displays a process's arguments and the ps e command 
displays a process's environmental variables. You can prevent users from seeing 
the arguments and environmental variables of other users by enabling variables 
in the /etc/rc.config file as follows:
 
   # rcmgr set TBL_ARGUMENTS_DISABLE 1
   # rcmgr set TBL_ENVIRONMENT_DISABLE 1
 
Root is always able to see other users' arguments and environment variables.
