I'm surprised this hasn't been answered already. STDOUT in perl is buffered by default. To make sure STDOUT is autoflushed, set $| to a true value early in your program. STDOUT is not buffered by default.

If another file handle has been selected, you may need to select STDOUT before setting $|.

See perldoc perlfun and perldoc perlvar fore more information on flushing and $|.
