Along with the other explinations, consider an example:
[EMAIL PROTECTED] trwww]$ perl
use warnings;
use strict;
foreach my $i ( 1 .. 5 ) {
print($i, '...');
sleep( 1 );
}
print( "\n" );
$| = 1;
sleep( 1 );
foreach my $i ( 1 .. 5 ) {
print($i, '...');
sleep( 1 );
}
print( "\n" );
^D
1...2...3...4...5...
1...2...3...4...5...
The first line is all printed out at once. The second line prints '1...'
then waits a second then prints '2...' and so on.
