HI

How do we check if a particular user has logged off. I only know how to check if a user logged in either by using who, w or last but don'thave an idea of how to check if a user has logged off.

Any idea?

you can check doing:

last <username> and that will list all the sessions od that user.

hope that helps

I don't quite see what your problem is...

Code:

who -u | grep "user"

should tell you if a user is logged in or not - if it produces output, then that user is logged in. If there is no output, then that user isn't logged in.

Or am I misunderstanding you?

What i mean is that, the script should detect if a certain user has logged off and also inform me which user logged off.

when using last to check those who logged in, it indicates that by a phrase "still logged in" and I want to know how i can see if one of the users who logged in has logged off/out.

Thanks

who -u |grep -i "user"> /dev/null
if [ $? -eq 0 ];
then
echo "User is Logged In";
else
{
echo "User Logged Off"
}
fi

Also note if user is never logged in then also it will say User logged off
