UNIX for Dummies Questions & Answers

when users ask for certain information about their systems. from my knowledge, I know that I'm supposed to go into the /var/adm file system of that user. now, can someone tell me what information exactly is contained in the /var/adm filesystems. I mean I want to know what information it is exactly in the /var/adm that users will possibly want to know. Please, if you have any idea, please, state them for me

thanks in advance

var/adm is a folder that contains log files such as wtmp , sulog etc., .... user reports and profiles cud be found in their respective logins ... for ex. if user abc exists ... the path wud be /usr/abc .
The history of the user is in a hidden file ._history or something , the group they belong and profile is in a .profile file ... look around ..
