The idea is to read until the end-of-file is reached, pause for awhile, then try reading again. However, reaching EOF sets a flag in the file handle and subsequent reads will fail. The trick is to reset the EOF flag with a seek command, either seek($fh,0,1) or $curpos = tell($fh); seek($fh,$curpos,0); -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
