I've got a file for which I use 'stat' to acquire its information, but
stat gives you numeric uid and gids. I need to get to the actual
username and groupname. How can this be done?

I am parsing some XML and trying to write the tags to a table. Here is

Column | Type | Modifiers

Nevermind. Got it figured out. Turns out I had a bad environment
variable that was trying to insert into a parallel DB in which the
ref_id field was defined as 'integer' instead of 'text'.

I installed OpenBSD's Apache but the default configuration is that httpd
runs chroot'd to /var/www for security. This is fine, except that for
the life of me, I cannot get my Perl CGI scripts to run. I've tried
linking /usr/bin/perl into /var/www but that doesn't work because of the

This is correct. When you include something the last line has to return
a true value, so people often stick a 1; at the end. Consider it a bit
of plumbing that a module or library just has to have.

OK apparantly I have a scoping problem below. If I add this line:

not visible inside it?

Yes. DBI has support for PostgreSQL. You can perform almost any
transaction through it that you would at the command line.

You'll be waiting a long time. Perl quickly moves into scientific
notation and can handle arbitrarily large values. I wrote a similar
program a while back and got bored with it when the count hit about
10^17. :)

You should always perform all error checking in any language to ensure
that your program, if it fails, declines gracefully. One of the
greatest shortcomings of C is that error checking is entirely manual,
and you simply must, in every real-world application, check the return

strftime is an interface to a C function of the same name. It's a
fairly common function in many applications that have to deal with dates

My Perl libary consists of Learning Perl, Programming Perl, The Perl

Most people probably don't need all those, and I probably wouldn't have

I generally like the O'Reilly Perl books, and I've had good luck with

The quest for an email validation script is becoming ancient and

the short answer is that there's no sure-way to validate email. There's

I.E., given this:

He wants the expression to evaluate true if $var contains the string

I have a subroutine that will receive parameters as follows:

This is perfect. The input is coming from a CPAN module so I'm fairly
confident that the number of entries will be even, but checking is
always a good idea.
You may want to check first that the list has an even number of entries:
die Invalid parameters if @_ % 2;
but after that it's just:
I'm not 100% confident that'll work as written. I *think* that if the
open is successful then the die will never execute and that 'if' will
never get checked. If the 'open' is successful on writing to a
non-existant file, I'm not sure if this solution will correct it.

If not for the need for attachments, I'd suggest using the 'mail' shell
