perl -f检查无法识别文件

我有一个perl脚本，通过一个包含几千个文件的文件夹 .

当我开始编写脚本时，我不知道perl File :: Find函数，所以为了列出结构中的所有文件，我使用了以下内容：

open (FILES, "$FIND $FOLDER -type f |");
while (my $line = <FILES>) {...}

然而，现在我想我会尝试从perl执行此操作，而不是启动外部程序 . （除了想要学习使用File :: Find之外，没有其他理由做这个改变 . ）

试图学习File :: Find find函数的语义我在命令行上尝试了一些东西，并将输出与find的输出进行了比较 .

奇怪的是，程序找到的文件有1个，但perl函数会跳过 .

找工作：

machine:~# find /search/path -type f | grep UNIQ
/search/path/folder/folder/UNIQ/movie_file_015.MOV
/search/path/folder/folder/UNIQ/movie_file_145.MOV
/search/path/folder/folder/UNIQ/Thumbs.db

machine:~# find /search/path -type f | wc -l
    6439

Perl失败了：

machine:~# perl -e 'use File::Find; find(sub { print $File::Find::name . "\n" if -f }, "/search/path");' | grep  UNIQ
/search/path/folder/folder/UNIQ/movie_file_145.MOV
/search/path/folder/folder/UNIQ/Thumbs.db

machine:~# perl -e 'use File::Find; find(sub { print $File::Find::name . "\n" if -f }, "/search/path");' | wc -l
    6438

更改为排除文件夹而不是包含文件有效：

machine:~# perl -e 'use File::Find; find(sub { print $File::Find::name . "\n" unless -d }, "/search/path");' | grep  UNIQ
/search/path/folder/folder/UNIQ/movie_file_015.MOV
/search/path/folder/folder/UNIQ/movie_file_145.MOV
/search/path/folder/folder/UNIQ/Thumbs.db

只有文件之间的区别是大小：

machine:~# ls -l /search/path/folder/folder/UNIQ/
total 4213008
-rw-rw-r--    1 user users    4171336632 May 27  2012 movie_file_015.MOV
-rw-rw-r--    1 user users    141610616 May 27  2012 movie_file_145.MOV
-rw-rw-r--    1 user users       20992 May 27  2012 Thumbs.db

有问题的机器上的Perl很旧但不古老：

machine:~# perl -version

This is perl, v5.8.8 built for sparc-linux

这是一个已知的bug还是什么？

或者我是否达到'-f'的大小限制？该文件几乎是4GB，是选择中最大的 .

或者我的测试（如果-f）选择不当？

EDIT [尝试统计文件]：

大文件失败

machine:~# perl -e 'use Data::Dumper; print Dumper(stat("/search/path/folder/folder/UNIQ/movie_file_015.MOV"));'

小文件有效

machine:~# perl -e 'use Data::Dumper; print Dumper(stat("/search/path/folder/folder/UNIQ/movie_file_145.MOV"));'
$VAR1 = 65024;
$VAR2 = 19989500;
$VAR3 = 33204;
$VAR4 = 1;
$VAR5 = 1004;
$VAR6 = 100;
$VAR7 = 0;
$VAR8 = 141610616;
$VAR9 = 1349281585;
$VAR10 = 1338096718;
$VAR11 = 1352403842;
$VAR12 = 16384;
$VAR13 = 276736;

二进制'stat'适用于这两个文件

machine:~# stat /search/path/folder/folder/UNIQ/movie_file_015.MOV
  File: "/search/path/folder/folder/UNIQ/movie_file_015.MOV"

也：

machine:~# perl -e 'stat("/search/path/folder/folder/UNIQ/movie_file_145.MOV"); print $! . "\n";'
Bad file descriptor

machine:~# perl -e 'stat("/search/path/folder/folder/UNIQ/movie_file_015.MOV"); print $! . "\n";'
Value too large for defined data type

EDIT2 ：

问题解决了”：

machine:~# perl -e 'stat("/search/path/folder/folder/UNIQ/movie_file_015.MOV"); print $!{EOVERFLOW} . "\n";'
92
machine:~# perl -e 'stat("/search/path/folder/folder/UNIQ/movie_file_145.MOV"); print $!{EOVERFLOW} . "\n";'
0

作品：

# perl -e 'use File::Find; find(sub { print $File::Find::name . "\n" if -f or ( $!{EOVERFLOW} > 0 and not -d) }, "/search/path");' | grep UNIQ
/search/path/folder/folder/UNIQ/movie_file_015.MOV 
/search/path/folder/folder/UNIQ/movie_file_145.MOV 
/search/path/folder/folder/UNIQ/Thumbs.db
