Ok, so I have some sub routines similar to what you see below, my issue is that the print function is not printing out until the actual command is complete, I want it to pri
Thanks! Can you show me an example of how to use $| I am unfamiliar, this place never fails lol –
Will this do?
$| = 1;
print "This is now unbuffered printing. "
sleep 3;
print "You no longer have to wait for the NL character. ";
sleep 3;
print "\n";
STDOUT is usually line-buffered, so you won't see your output until you print a newline. You can set $| before printing to force your output to be printed.
To turn on autoflushing after each print, set $|
to 1:
$| = 1;
print "Enter a number between 3 and 5: ";
chomp( my $answer = <STDIN> );
(Note that $| isn't actually a single value, it is tracked separately for each filehandle. When you set it, it affects the setting for the currently selected filehandle (see select).
