用80行的bash编写一个RSS阅读器

在这个信息爆炸的时代，RSS阅读器成为了许多人获取信息的重要途径。而今天，我将教你如何使用80行的bash代码编写一个简单而强大的RSS阅读器。

首先，我们需要准备一个bash环境和一个简洁的RSS阅读器。我推荐使用YR（https://yobibyte.github.io/yr.html），一个优雅而高效的RSS阅读器。接着，我们就可以开始编写我们的80行bash代码了。

打开一个新的bash文件，开始编写以下代码：

“`bash

#!/bin/bash

FEED_URL=”YOUR_RSS_FEED_URL”

curl -s $FEED_URL | grep -E “|<link>” | sed ‘s/<title>/\n/g’ | grep “<link>” | sed ‘s/<link>/\n/g’ | sed ‘/^$/d’ | sed ‘s/[^>]*>//g’ | sed ‘/^$/d’ | sed ‘s/\</\n/g' | grep "^http" > rss_feed.txt</p> <p>while read line; do</p> <p>echo “$line”</p> <p>read -p “Press enter to continue”</p> <p>xdg-open “$line”</p> <p>done < rss_feed.txt</p> <p>“`</p> <p>在上面的代码中，`FEED_URL`是你想要订阅的RSS源的URL。通过使用`curl`命令获取RSS源的内容，并使用一系列的`grep`、`sed`和`xdg-open`命令，我们可以将RSS源中的标题和链接提取出来，并逐个展示给用户。</p> <p>通过这个简短的80行bash代码，你可以快速地搭建一个强大的RSS阅读器，为自己打造一个个性化的信息获取工具。尽情享受这个DIY的乐趣吧！</p> <p><a href="https://yobibyte.github.io/yr.html">详情参考</a> </p> <p>了解更多有趣的事情：<a target="_blank"
