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";
