perl读写文件

1，从命令行读取文件或者文件夹
2，支持无限多个文件或者文件夹参数，不分顺序
3，可以识别非法文件和文件夹，退出并提示

组合一：

FileDirHelper.pm

#!/usr/local/bin/perl
#Ljl
package FileDirHelper;

my ($size,$dircnt,$filecnt) = (0,0);
my @files;
my @AllDirs;

sub getAllFiles{
	my $dir=shift;
	lsr_s($dir);
	print "Load $filecnt files,$dircnt directory. $size bytes.n";
	return @files;
}

sub getAllDirs{
	my $dir=shift;
	lsr_s($dir);
	return @AllDirs;
}

sub getDirDetail{
	my $dir=shift;
	lsr_s($dir);
	return ($size,$filecnt);
}

sub lsr_s($) {
    my $cwd = shift;
    my @dirs = ($cwd.'/');

    my ($dir,$file);
    while ($dir = pop(@dirs)) {
        local *DH;
        if (!opendir(DH,$dir)) {
            warn "Cannot opendir $dir: $! $^E";
            next;
        }
        foreach (readdir(DH)) {
            if ($_ eq '.' || $_ eq '..') {
                next;
            }
            $file = $dir.$_;         
            if (!-l $file && -d _) {
                $file .= '/';
                push(@dirs,$file);
            }
            process($file,$dir);
        }
        closedir(DH);
    }
}



sub process($$) {
    my $file = shift;    
    if(-f $file){
    	#print $file,"n";
    	push @files,$file;
    }else{
      push @AllDirs,$file;
    }
    if (substr($file,length($file)-1,1) eq '/') {
        $dircnt++;
    }
    else {
        $filecnt++;
        $size += -s $file;
    }
}
