Re: Date in Filename

Provided that your script name does not contain the percent sign :

use strict;
use POSIX;

my $filename = strftime "$0.%Y%m%d-%H%M%S.log", localtime();

strftime is a really cool function for timestamps, but documentation is scarce. The DateTime module has more/better documentation on the format strings than the stock Perl/POSIX documentation.

perl -MHTTP::Daemon -MHTTP::Response -MLWP::Simple -e ' ;    # The  
$d = new HTTP::Daemon and fork and getprint $d->url and exit;#spider
($c = $d->accept())->get_request(); $c->send_response( new   #in the
HTTP::Response(200,$_,$_,qq(Just another Perl hacker\n))); ' #  web

Tsk, passing unchecked data (`$0`) to `strftime` ... shame! What if somebody creates a symlink to the script, and that symlink's name contains a "%"; or what if there's a "%" in the path leading to the script? Then `strftime` is gonna get Really Mad, that's what. -- Chip Salzenberg, Free-Floating Agent of Chaos	[reply] [d/l] [select]
