Answer» i can do it with who and last command but i get the details of pseudoterminals which i have opned not the details of my login . i NEED to know the details of my PREVIOUS login's you can run a script that runs each time a user login, grab his name to a file.u can run the script in a PROFILE of users,so when theire PROFILES run, the scrpt also runs,and grab the username,the time and other info of ur interest to a central of NETWORK file,so users who login from any machine can be tracked....
