为什么这种排除不适用于长句？
Why this exclusion not working for long sentences?
命令
perl -ne 'print unless /.[240,]/' input.txt > output.txt
其中包括一些长度超过 240 个字母的句子。为什么？

您使用了错误的语法：[] 用于匹配字符 class，而此处您试图匹配 . 的多次出现，这可以使用 {}:
来完成
perl -ne 'print unless /.{240,}/' input.txt > output.txt
此外，正如 salva 在评论中所建议的，模式可以缩短为 .{240}:
perl -ne 'print unless /.{240}/' input.txt > output.txt
