-d:不匹配我的文件夹

-d : not matching my folder

我对这段代码有疑问。它匹配目录 ... 但不匹配其他目录。你能解释一下为什么吗?

my $Checked_directory = $Tested_directory . '\Sources';

opendir(Checked_directory, $Checked_directory)
    or print STDOUT "\n 101 - Cant open $Checked_directory: $!\n";

@files = readdir(Checked_directory);    #etablished the list of file in the checked folder

foreach my $fileToTest (@files) {

  print $fileToTest . "\n";    #debug

  if ($fileToTest =~ m/.jpg$/) {
    print 'file...  ' . $fileToTest . "\n";
    $Localisation_file = $Tested_directory . '\Sources\' . $fileToTest;    #file to test
  }
  elsif (-d $fileToTest) {
    print ">>>>" . $fileToTest . "\n";
  }
}

closedir(Checked_directory);

@files中的名称,你似乎知道,没有任何路径信息,这意味着-d在当前工作目录中查找它们,找不到它们, 并报假。 -e(存在)测试也会发生同样的情况。

你应该这样修改你的代码。请注意,以大写字母开头的标识符是为全局标识符保留的。使用裸词文件和目录句柄也是一个坏主意——词法句柄是当前的最佳做法。

my $checked_directory = "$tested_directory\Sources";

opendir $checked_dh, $checked_directory
    or print STDOUT "\n 101 - Cant open $checked_directory: $!\n";

while (my $file_to_test = readdir $checked_dh) {

  print "$file_to_test\n";

  my $localisation_file = "$tested_directory\Sources\$file_to_test";

  if (-d $localisation_file) {
    print ">>>> $file_to_test\n";
  }
  elsif ($file_to_test =~ /\.jpg$/) {
    print "file... $file_to_test\n";
  }
}

closedir $checked_dh;

好的,所以对您的代码进行快速测试 - 我模拟了一个目录结构。看起来你是 'doing it windows style?'

我正在使用这个:

use strict;
use warnings;

my $Tested_directory = 'C:\temp';

my $Checked_directory = $Tested_directory . '\Sources';
opendir( Checked_directory, $Checked_directory )
    or print STDOUT "\n 101 - Cant open $Checked_directory: $!\n";
my @files = readdir(Checked_directory)
    ;    #etablished the list of file in the checked folder
foreach my $fileToTest (@files) {
    print "File: $fileToTest \n";    #debug
    if ( $fileToTest =~ m/.jpg$/ ) {
        print 'file...  ' . $fileToTest . "\n";
        my $Localisation_file =
            $Tested_directory . '\Sources\' . $fileToTest;  #file to test
    }
    else {
        print "\n$fileToTest is not a jpg\n";
    }

    if ( -d $fileToTest ) {
        print ">>>>" . $fileToTest . "\n";
    }
}
closedir(Checked_directory);

我创建了一个如下所示的目录结构:

 Directory of C:\temp\Sources

22/01/2015  13:07    <DIR>          .
22/01/2015  13:07    <DIR>          ..
22/01/2015  13:07                 0 notajpg.jpg
22/01/2015  13:04    <DIR>          SubDir
22/01/2015  13:07                 6 wibble.txt
               2 File(s)              6 bytes

确实 - 我的 'SubDir' 没有在输出中添加 >>>> 前缀。

File: . 
>>>>.
File: .. 
>>>>..
File: notajpg.jpg 
file...  notajpg.jpg
File: SubDir 
File: wibble.txt 

所以您的 .jpg 位工作正常。但是哪里 '。'和 '..' 作为 dirs 拾取,'SubDir' 没有。

原因好像和路径有关。 ... 存在于每个目录中,因此无论脚本路径如何,测试都可以进行。

您需要针对 ( -d "$Checked_directory\$fileToTest" )

进行测试

给予:

use strict;
use warnings;

my $Tested_directory = 'C:\temp';

my $Checked_directory = $Tested_directory . '\Sources';
opendir( Checked_directory, $Checked_directory )
    or print STDOUT "\n 101 - Cant open $Checked_directory: $!\n";
my @files = readdir(Checked_directory)
    ;    #etablished the list of file in the checked folder
foreach my $fileToTest (@files) {
    print "File: $fileToTest \n";    #debug
    if ( $fileToTest =~ m/.jpg$/ ) {
        print 'file...  ' . $fileToTest . "\n";
        my $Localisation_file =
            $Tested_directory . '\Sources\' . $fileToTest;  #file to test
    }
    elsif ( -d "$Checked_directory\$fileToTest" ) {
        print ">>>>" . $fileToTest . "\n";
    }
}
closedir(Checked_directory);
