1、第一种方式，不管系统资源，如果文件多的话，会是一个相当大的数组 内存可能耗尽。#!/usr/bin/perl -w use strict; use File::Find::Rule; my @files = File::Find::Rule->file()->name("*.pl")->in

splice函数有三个作用。第一个作用是向数组中间的一部分插入内容。例如： @d=(1..9); my @e=("a".."f"); splice(@d,2,2,@e);#目标数组, 插入起始位置, 覆盖长度, 插入数组将会得到12abcdef56789，注意这里是从第二个开始插入，不是从下标为2的元素开始插入的。splice的第二个功能是删除，例如在刚才的代码上面再加上：splice(@
