在Linux没找到合适的壁纸软件，于是估摸着自己简单实现了一个。功能由三部分实现:bgwall 软件主体,由 ruby 编写的脚本。调度图片获取脚本，以及壁纸更换。./fethch_script/ 存放获取图片的脚本。./post_script/ 存放对获取后的图片进行后期加工的脚本。效果源码如下 (相当之简陋 勉强能用)#!/usr/bin/env ruby# encoding:utf-8# -*- coding: UTF-8 -*-require 'fileutils'# 壁纸更换间隔DURA = 30 * 60IMGS = 2# 图片脚本调用方式 INDEX 顺序; RANDOM 随机FETCH = 'INDEX'VALS = { :INDEX_FETCH => 0, :COUNT_FETCH => 0 }# 图片临时存放路径IMG = '/tmp/bgwall/'FSC = './fetch_script/'PSC = './post_script/'CBG = "#{IMG}/bgwall_current.png"NBG = "#{IMG}/bgwall_next.png"def call_bg_script(script, img_dir, count)return nil if script.nil?file = `#{script[0]} #{img_dir}/#{script[1]}_#{count} #{count}`.chompputs ">>> bg [#{file}] fetch by #{script[1]}"return fileenddef call_post_script(img_path)Dir::open(PSC).filter{|f| f.start_with? /\d+/ and File.executable?
