    |   |   |-- rev1
    |   |   |-- rev2

What I have tried:

my @logs = glob "task.*";
for (@logs) {
    next if $_ eq "task.*";

Use my solution to your question How do I remove the subdirectories from the directory struture using Perl?[^] as starting point (~~untested~~ EDIT: tested and fixed errors):

PERL

sub DelTaskFiles{
    my ($workdir) = shift;
    #print "Processing '$workdir'\n";
    my $mask = $workdir . '/*';
    # glob: Return list of filename expansions for search mask
    my @files = glob $mask;
    foreach $f (@files)
    {
        # Process sub directories
        if (-d $f)
        {
            DelTaskFiles($f);
        }
        else
        {
            my $filename = basename($f);
            if ($filename =~ /^task/)
            {
                #print "Removing $f\n";
                unlink $f;
            }
        }
    }
}

DelTaskFiles('/home/rpasa/demo_checklist');

}
General rule:
If you need to process subdirectories use a recursive function that processes the directories. In each directory iterate over the files and perform the required action for matching files.
