Hi, vinoth.ree, soonix, thank you for pointing out the perl buffer. While this issue might not apply. I execute this script on various machines and it always goes ok. Only on this IBM machine with TTY console configured this problem shows up. So I am confused a lot. What is more, the script resumes when I login console and hit "return" next day.
