Thank you Nagarajan G!!
Exec works perfect to redirect from inside!

I try to get the print-out simultaneously and trying to do it with 'tail -f'

And I've get rock-n-roll:
to start 'tail' need and continue - need to run tail background (... & )
to stop 'tail' when it is done - need to know it's PID
but it is bad idea to kill 'tail' on end of screept - it could exit in a midle
so need to run monitoring of the script to stop the tail rigt after t'tail' start

Is this seems doable? Because by now I have some problem to get PID and kill it. (Actually I did it from outside script and get mess with PIDs)

Any oppinion?

NAME
mtail - tail variant designed for web developers monitoring logfiles SYNOPSIS
mtail [options] <file>... DESCRIPTION
MonkeyTail allows a user to tail multiple files on both local and remote hosts and clearly marks inactivity by putting 5 newlines in the output whenever a pause in output over 3 seconds is detected. MonkeyTail is implemented a fairly simple wrapper script around standard tail, ssh, and sudo. OPTIONS
-q Quiet mode --quiet " " -n Output the last N lines of each file before tailing (defaults to 0) <file>... Files to tail. These can specified in the following ways: @<groupname> - expands the group (from .mtailrc) to a list of files to tail <filename> - tails a local file. +<filename> - attempts to sudo and tail a local file (will prompt for pwd if required). <remotehost>:<filename> - attempts to invoke tail via ssh on a remote host. +<remotehost>:<filename> - attempts to invoke sudo tail via ssh on a remote host (will prompt for pwd if required).
