disabling " who " command
 

how can i disable "who" command so that the users connected to my PC couldnt see who else is connected.
i am newbie to linux ..
is there any other command by which users can see details of other users .. how do i disable that if any ?


where are the logs stored for user login's

One way is to change the file permissions of who so they are not executable by users other than root. Other commands that show a list of who is logged in are: w and finger.

how do i change the permission of users ?

you should change the permissions of the program, the command is chmod and the numbers will change depending on what you want to do. I think would only let root run that program.:study:

i was asking about changing permission for users.

Like i dont want my users to use the command who, finger or w

how do i set that ?
