是否有一个命令行程序可以获取包含英文文本的文件，分析该文本并输出其可读性分数？
例如，如果向程序输入文本，程序应该输出 Flesch-Kincaid 等级、McLaughlin 的 SMOG 等级等。
我相信官方存储库中存在这样的程序，但我记不住它的名字。也有可能我记错了。

这diction 
软件包中包含一个工具，名为style：
Style分析文档写作风格的表面特征。它打印出各种可读性等级、单词、句子和段落的长度。它可以进一步定位具有某些特征的句子。
例如，如果我评估您的问题主体（保存在文件中flux_question）以打印可读性指数（ARI）超过 10 的句子：
$ style -r 10 flux_question
flux_question:1: Is there a command line program that takes a file containing English text, analyzes the text, and outputs its readability scores?
flux_question:2: For example, if one feeds the program a text, the program should output the Flesch-Kincaid grade level, McLaughlin's SMOG grading, etc.
readability grades:
Kincaid: 10.2
ARI: 10.8
Coleman-Liau: 12.5
Flesch Index: 51.1/100
Fog Index: 12.0
Lix: 48.6 = school year 9
SMOG-Grading: 11.2

为了过滤输出，您可以使用例如tail -n8仅获取等级或grep 'Flesch\|SMOG'仅打印 Flesch 指数和 SMOG 等级：
$ style flux_question | grep 'Flesch\|SMOG'
Flesch Index: 51.7/100
SMOG-Grading: 11.2
