perl – 如何遍历目录中的所有文件;如果它有子目录,我也想遍历子目录中的文件

opendir(DIR,"$pwd") or die "CAnnot open $pwd\n";
    my @files = readdir(DIR);
    closedir(DIR);
    foreach my $file (@files) {
        next if ($file !~ /\.txt$/i);
        my $mtime = (stat($filE))[9];
        print $mtime;
        print "\n";
    }

基本上我想要记下目录中所有txt文件的时间戳.如果有一个子目录,我也希望在该子目录中包含文件.

有人可以帮我修改上面的代码,以便它也包含子目录.

如果我在Windows中使用下面的代码我获取文件夹中所有文件的时间戳,甚至在我的文件夹之外

@H_512_2@my @dirs = ("C:\\Users\\Peter\\Desktop\\folder"); my %seen; while (my $pwd = shift @dirs) { opendir(DIR,"$pwd") or die "CAnnot open $pwd\n"; my @files = readdir(DIR); closedir(DIR); #print @files; foreach my $file (@files) { if (-d $file and !$seen{$filE}) { $seen{$filE} = 1; push @dirs,"$pwd/$file"; } next if ($file !~ /\.txt$/i); my $mtime = (stat("$pwd\$file"))[9]; print "$pwd $file $mtime"; print "\n"; } }

use warnings;
use Strict;

my @dirs = (".");
my %seen;
while (my $pwd = shift @dirs) {
        opendir(DIR,"$pwd") or die "CAnnot open $pwd\n";
        my @files = readdir(DIR);
        closedir(DIR);
        foreach my $file (@files) {
                next if $file =~ /^\.\.?$/;
                my $path = "$pwd/$file";
                if (-d $path) {
                        next if $seen{$path};
                        $seen{$path} = 1;
                        push @dirs,$path;
                }
                next if ($path !~ /\.txt$/i);
                my $mtime = (stat($path))[9];
                print "$path $mtime\n";
        }
}
