perl使用print输入数据到文件

#!usr/bin/perl

use utf8;

#引入utf8模块 脚本内的字符串使用utf8作为编码格式

binmode(STDOUT,":encoding(gbk)");

#标准输出使用gbk作为编码格式，也可以把gbk改为gb2312

binmode(STDIN,":encoding(gbk)");

#如果涉及到输入流，例如读文件，不加这条读中文文件会出现乱码

binmode(STDERR,":encoding(gbk)");

#如果异常错误中的字符串有中文，请加上STDERR，否则也会出现乱码

open( DATA, "> Error.txt" )

  || die "Unable to open error for write! - $!\n";

%IOLIST=('李白',{'age','18','height','185','weight','60kg'},

'李4',{'age','21','height','182','weight','60kg'},

);

dumplist(\%IOLIST);

sub dumplist

{

    my $LIST = shift;

    my $legend = 0;

    foreach $item (sort keys %$LIST)

    {

        my @attributes = ();

        my @legen = ();

        print "$item:\n";

        foreach $attr (sort keys %{$$LIST{$item}})

        {

            push(@legen, $attr);

            push(@attributes, $LIST->{$item}{$attr})

        }

        print @legen , "\n" if $legend == 0;#打印数组,ageheightweight

        $legend++, print DATA "item:", join(',', @legen), "\n\n" if $legend == 0;

        print DATA "$item:\t", join(',    ',@attributes),"\n\n";

    }

}

输出结果：
