Perl实现遍历目录例子（perl数组push）学到了

#!/usr/bin/perl

 use strict;

 use warnings;

 use Encode qw/from_to/;

 my $path=”e:/CSS Design”;

 my $filecount=0;

 sub parse_env {   

     my $path=$_[0]; #或者使用 my($path)=@_; @_类似javascript中的arguments

     my $subpath;

     my $handle;

     if (-d $path) {#当前路径是否为一个目录

         if (opendir($handle, $path)) {

             while ($subpath=readdir($handle)) {

                 if (!($subpath=~ m/^\.$/) and !($subpath=~ m/^(\.\.)$/)) {

                     my $p=$path.”/$subpath”;

                     if (-d $p) {

                         parse_env($p);

                     } else {

                         ++$filecount;

                         print $p.”\n”;

                     }

                 }               

             }

             closedir($handle);           

         }

     }

     return $filecount;

 }

 my $count=parse_env $path;

 my $str=”文件总数：”.$count;

 from_to($str, “utf8”, “gbk”);

 print $str;
