I need to sort the keys in a hash. The keys are the question number
and the values are the student's answer. A numeric sort with = won't
work since retaking a missed question (say, 2) produces the new key,
2h with its new answer. A representative hash might look like this
1 = b
2h = c
3 =

I have written a Perl script which I have used for years to decrypt at the

Hi,
I did the best book purchase in years: The Perl Cookbook. They have an
example that seems to come right from Larry Wall himself. And I don't
get it. I can use it but I don't understand why it works with wildcards.
$op = shift or die Usage: rename expr [files]\n;
chomp (@ARGV = STDIN)

Hi all,
Although I've read the docs and have been practising with it, I'm a bit
confused on the use of eval().
For some reason, it took a few swings of the hammer to get past wanting
to look for array elements within $@ :P
I think I now understand the dangers of using eval() to trap errors,
I'm using the Daemon::Easy module to write a basic Perl daemon, but I'm
wondering if there is a way to stop the daemon from within the script (as
opposed to running ./script.pl stop)? Currently I have a subroutine to do
this, but it doesn't seem to cleanly erase the pid file.
