Hello. I am not asking about redirecting.
I am finding a way to remap stdin/stdout in program executing. like
screen... It can make virtual windows and emulate executing program in
For another example, think of changing password by a user program. A
user can change his own password with passwd, the setuided program. We
are to run passwd program and change password without any typing. I
think it is possible. I can make program which does almost same with
TCP/IP connection(to automatically login, and run password, and change)
but I am not saying about that...
Sorry for my poor english. And Thank you
