使用Shell命令从网站抓取/下载mp3文件

Question

首先，这不是任务，这是一个帮助我了解Shell知识的侧切线项目。我正在尝试制作一个简单的shell脚本，当给定一个命令文本文件时，依次运行每个脚本，直到执行完为止。

到目前为止，我已经提出：

#!/bin/bash
input="/home/gome/Downloads/darknetdiaries.txt"
while IFS= read -r line
do
  echo "$line"
  $line
done < "$input"

在单独的文本文件中，我有：

目前没有任何错误，但似乎只是打印出所有行而没有做。这是一张图片：

我非常感谢您的帮助！

编辑：

以上脚本按其应有的方式工作。一个文件是您要运行的所有命令的文本文件，另一个文件是Shell脚本。

在文本文档中，我用指向Dark Net Diaries播客的所有当前剧集的链接填充了这些链接：为了获得所有链接，我首先必须使用Owasp Zap扫描网站并整理出URL。之后，只需将其弹出到文本文件中，然后在前面添加wget。

Answer 1

只需在echo "$line"之后添加命令：

#!/bin/bash
input="PATH_TO_TEXT_FILE"
while IFS= read -r line
do
  echo "$line"
  $line
done < "$input"

或从第二个while循环中删除COMMAND_on。
