[ale] perl, *nix, or user error

[John Wells]

Your output is most likely being buffered.

Setting $| = 1 should do it....

> Ok, I have tried this on FreeBSD, Linux, and HP-UX.  A very simple script
that I can not seem to make work the way I want.

********************* BEGINING OF SCRIPT ************************

#!/usr/bin/perl -w

print &quot;Hello World &quot;;

$counter = 0;
while ($counter &lt; 10)
{
print &quot;$counter &quot;;
$counter++;
sleep 1;
}

******************* END OF SCRIPT **********************

OK, I expect it to print Hello World, then 0-9 at 1 second intervals, all
on the same line, instead it prints it all out at once, 10 seconds after
starting the program.

It will print things out one at a time if I put a 'n' at the end of any
'print' lines, but I want the count on one line.

Can anyone help? Do I need to flush the buffer or something?
