Question

请原谅我的无知。我是Unix的新手。这可能听起来很傻。我在包含一些日志详细信息的文件上运行以下命令。

cat ./Logfile | uniq -c

现在，当文件包含超出屏幕宽度的超长行时，它会在文本查看器上为用户创建一个水平滚动条。

有没有我可以将文本包装到下一行，以便结果看起来清晰易读并且对用户滚动友好？看起来像下面的东西。

23  This is just a sample result text that has come up to be very long but was 
    WRAPPED to the next line so that the results are displayed in a scroll fri
    endly format. Is that really possible?

Answer 1

您可以使用fold实用程序，例如：

$ cat text
This is just a sample result text that has come up to be very long but was WRAPPED to the next line so that the results are displayed in a scroll friendly format. Is that really possible?

$ fold -s -w 80 text
This is just a sample result text that has come up to be very long but was
WRAPPED to the next line so that the results are displayed in a scroll friendly
format. Is that really possible?

Answer 2

您使用的终端是什么？你在哪里看到这些滚动条？

通常输出应该按预期包装，除了换行从行的开头开始而不是对齐，所以我希望你从命令中得到以下输出：

 23  This is just a sample result text that has come up to be very long but was 
WRAPPED to the next line so that the results are displayed in a scroll fri
endly format. Is that really possible?

编辑：谢谢你的澄清，现在我了解你的情况。我认为你可以像其他人在这里建议的那样使用这个折叠，但是在uniq之后管道它：

cat ./Logfile | uniq -c | fold -s -w 80 > result.txt

如何从grep中包装长结果
