背景

前端时间在喜马拉雅上偶然听到牛大宝说的有声小说神通板砖，说的很是幽默，听的正起劲的时候开始收费了，于是我就在网上找了下看看有没有免费版，一搜果然有，但该网站上广告太多了，于是我就写了个小脚本可以批量下载的，供大家学习，如果您使用该脚本用于任何非法用途，均与本站无关。

思路

  1. 找到可以免费下载资源网站
  2. 针对该网站html进行分析并编写下载脚本
  3. linux命令行自动顺序播放

实施

找到可以免费下载资源网站

自动播放脚本

下载好的音频文件都是以数字编号的，所以可以播放完一个自动进行下一个，并且记录当前播放记录，方便下次继续播放 将下面的脚本保存为play.sh

#!/usr/bin/env bash

basepath=$(cd `dirname $0`;pwd)
cd $basepath
echo "workspace [$basepath]"

posfile="stbz.pos"

if [ ! -f "$posfile" ]; then
    echo '1.m4a' > ${posfile}
fi

pos=$(cat ${posfile})
state="start"

for name in `cat ./stbz.lst`;do
    if [ $state = "start" ]; then
        if [ $pos = $name ]; then
            echo "begin play ${pos}"
            mplayer $name 1>> /dev/null 2>>err.txt || exit 1
            state="play"
            echo "${name}" > ${posfile}
        fi
    else
        echo "begin play ${name}"
        echo "${name}" > ${posfile}
        mplayer $name 1>> /dev/null 2>>err.txt || exit 1
    fi
done
