For all intents and purposes, it is impossible to redirect the stdin/stdout
of a running process.

where files in /dev some pseudo-devices designed for.
After doing this you can manage all in/out streams for that command.

install it
run "screen"
start long-running process in the screen session
when you're done, hit ctrl-a followed by d (for detach)
later when you want to come back to it, type screen -r
it's fab.

screen -m -d -S coolname /bin/app
screen -r coolname

1. Suggestions for redirecting stdin/stdout from a running process?
I'm not a Linux/Unix expert so I was hoping someone here might be able to
help me with this. Suppose a process is running which makes use of stdin
and stdout (it has an interactive text-based interface). What I would like
to try and do is to make it possible for a user to login to the system, then
somehow redirect the stdout and stdin of the running process so that the
text-based UI could then be operated under the user's own login shell. Is
this possible? What I'm thinking is that the process could listen for a
certain signal, which would tell it to redirect it's stdout/stdin to a
different tty. The user who logged in and wants to interact with the
process would run a script or small program to send this signal.
Any thoughts?
Thanks!
