Is is possible to monitor output of a terminal session that is already running?

[Jack C. Mahaffey]

Is it possible to do something similar to "tail -f" output being sent to a terminal to watch what's being displayed? All output is text. Better yet, is it possible to redirect standard output of a process while it is already running?

Maybe tail -f /dev/pts/3 will work for the terminal?

I don't need to be interactive with the terminal.

I'm not sure that command will work, but its probably possible for the root user to grab the terminal output.

Its also possible to change it, which is why many admins make sure the terminal files are secure from such chickanery.

It can't hurt to try your command but i think its a differenet, temporary file you need to see.

The output may not be very user friendly.

I don't know if 'tail -f' will work. I kind of doubt it.

There is a third party application that will let you monitor, and even take control of, sessions on your machine. The product is called DoubleVision produced by Tridia. http://www.tridia.com/

I have used the product in the past and it works really well.

I'm trying it now. It looks like it's just hanging. Gonna give it some time.

Thanks Patrick. I'll look into it.
