I want to count how many users accessing our unix server.
The unix command should do the following :
i. list all users logged in to the server
ii. list of all users that their id , letsay any user id that has trailing id with "gues2008"
iii. simply count total users in (ii), but no duplication, ie, if there are more than one session user A had accessed, thenit shold considered as one.
iv. if possible , from the list (ii) can differentiate local access or remote access.
