Re: Sort an array which contains date formatted elements

in reply to Sort an array which contains date formatted elements

Late to the game I see, but for the sake of TIMTOWTDI here is my suggestion.
Use a Schwartzian Transform.

use Time::Local;

my %months;
@months{('jan','feb','mar','apr','may','jun','jul','aug','sep','oct','
+nov','dec')} = 0..11;
my @lines = 
    map{ $_->[1] }
    sort{
        $a->[0] <=> $b->[0]
    }
    map{
        chomp;
        my $val = $_;
        $val =~ s#webadmin_([^\.]+)\.log#my @t=split(/_/,$1);timelocal
+(0,0,0,$t[1],$months{$t[0]},($t[2]-1900))#e;
        [$val,$_];
    }<DATA>;
print "$_\n" for(@lines);
__DATA__
