Actually logins on any date for the same user will overwrite
since you're assigning a hash reference to the hash element each
time. I don't think grouping by login date was a requirement so a
structure more like this might make better sense:
$VAR1 = {
$username => [
{
'Login Date' => $logindate,
'DBServer' => $dbserver,
'Hostname' => $hostname,
'Login Status' => $status
},
{ ... },
{ ... },
{ ... },
]
};
Then you could iterate over it like so:
my @fields = (
'Login Date',
'DBServer',
'Hostname',
'Login Status',
);
for my $user (sort keys %info) {
print "$user\n";
print join("\t", @fields), "\n";
my $logins = $info{$user};
for my $login (@$logins) {
print join("\t", @{$login}{@fields}), "\n";
}
print "\n\n";
}
You'll want to read the standard perldocs to learn about data
types, slices, loops, etc. See `perldoc perl' for a list of core
perldocs that you may be interested in and begin reading. It's
really very important that you read through the core documents
when you begin. Until you do you won't be able to think of
solutions yourself.
Note that there are various ways to make the output more precise,
etc., depending on who or what will be reading it, etc. This is
just an example. You can RTFM to figure out how to make it
better. :) `perldoc -f sprintf' might be a good choice.

Recommendations for emacs customizations for editing Perl
I'd like to hear some recommendations from this list for customizations to emacs for coding Perl.One seemingly respected site, http://emacswiki.org/emacs/PerlLanguage, has a lot of links but unfortunately some are pretty dated. For example, the Perl Develop Environment, http://search.cpan.org/dist/Emacs-PDE/, last updated in 2008, wouldn't install because my version of Perl (5.16.1) was "too far out of date." So of course the question is, how up-to-date is emacswiki.org?As I say, I'm running Perl 5.16.1, and emacs 24.something. I do have cperl-mode.el, but there are also a lot of goodies out there like variable-name completion and templates that look very useful. I mostly don't want to be installing and troubleshooting stuff that hasn't been updated in five years and/or isn't "generally regarded" to be top quality.Thanks for any pointers or even advice about what to avoid :)Vic

Re: Recommendations for emacs customizations for editing Perl
Have been coding perl with VIM always. I'd like to hear some recommendations from this list for customizations to emacs for coding Perl. One seemingly respected site, http://emacswiki.org/emacs/PerlLanguage, has a lot of links but unfortunately some are pretty dated. For example, the Perl Develop Environment, http://search.cpan.org/dist/Emacs-PDE/, last updated in 2008, wouldn't install because my version of Perl (5.16.1) was "too far out of date." So of course the question is, how up-to-date is emacswiki.org?

You should be able to just copy and paste stuff from my config into there and restart Emacs. Some of the config is dependent on packages, which you can install from MELPA or ELPA. We're sort of skating on the edge of on-topic for Perl beginners here, so if what I'm saying doesn't make sense, you may want to look for basic resources on Emacs customization and start there. chrs, john.
