Yes, of course, that's what I'm doing now, but I wanted to do it
internally, control the file name, perhaps rotate it, etc :-)
Actually:
myprog | tee mytuil path/to/log
It has the effect that text to screen is written in chunks, may stop at
the middle of a line. So at the end each cycle, I issue a "flush(output);"
