logging stdout
Hello

I run a program that creates number of processes.
Is there a way of viewing their standard output on terminal and logging it to a log file simultaneously?

yes, look into 'man tee'

I mean, that i don't want to do it permanently , but from some point of execution. For example, the program and all its processes run, and when some error occures, i decide to switch to debugging mode and both view output on screen and save to log. May be durung this time new processes were created and i want to duplicate its output two. And after logging all needed data i switch back and only view output on screen.

screen may be able to do what you want. I don't know of anything else that can hide output then suddenly grab it back later.
