Attach to a processes output for viewing

Question

How would I \'attach\' a console/terminal-view to an applications output so I can see what it may be saying?

How would I detach from an applications output without k

Answer 1

I was looking for this exact same thing and found that you can do:

strace -ewrite -p $PID

It's not exactly what you needed, but it's quite close.

I tried the redirecting output, but that didn't work for me. Maybe because the process was writing to a socket, I don't know.
