you mean something like "who -u"?

[Steven E. Protter]

Shalom,

who -u will work to provide a best guess of who is currently logged in. Its based on data in the /var/adm/wtmp file and is not always accurate.

I don't know what you mean by the statement "i can close the shell which work on it?"

You can kill any process on the machine as root, which has these priviledges.

If you don't trust who(1), you can look at all non-root processes:
$ ps -fe | grep -v "^root"

Hi
the output of who -u command it is not out all user, if i am root the output only about the root user not another, if oracle and sql users using my server and i am root user how to see all these users and traking (last -oracle) and Expulsion from use the server
only.
thanks

>if oracle and sql users using my server and i am root user how to see all these users

If you are looking for the users "sql" and "oracle", you can find them with:
$ ps -fu sql -u oracle

If you want to find ALL users that are using sql or an Oracle database, that is much harder.

Hi
but remained how expulsion fro using the server.
namely only root user using the server.
thanks and best regards

(There are some words missing above.)
Are you asking how to exclude everyone but root from using the machine?

I assume you don't want to go to single user mode?

You could use wall(1m) to ask them to logout.
Or you could kill them and then /etc/profile prevent them from logging in. You would also have to stop networking so rlogin, remsh, ssh don't work.
