I'm helping a serverdude with a logfile summarization script. Since the script will run daily, he'd like the output file to be named for the date in format yyyymmdd
(with month and day leading-zero padded as needed).
The following snippet with localtime() and printf() are a start. But there's clearly something I'm overlooking or misunderstand. Suggestions for a Better Way To Do It?
thanks,

#!/usr/bin/perl -w
use strict;
my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(t
+ime);
printf ("%04d%02d%02d",$year+1900,$mon+1,$mday);
print "\n\n";
# result is 20010807
# good; exactly what was expected
my $ymd = printf("%04d%02d%02d",$year+1900,$mon+1,$mday);
print "$ymd";
print "\n\n";
# result is 200108071
# why the appended 1 ??
my $outfile = "$ymd.summary";
print "$outfile";
print "\n\n";
# result is 1.summary
# ????

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
