如何在文本文件中找出行尾? [英] How to find out line-endings in a text file?

问题描述

我正在尝试在bash中使用某些东西来显示打印而不是解释的文件中的行尾.该文件是SSIS/SQL Server的转储文件，正在被Linux机器读取以进行处理.

I'm trying to use something in bash to show me the line endings in a file printed rather than interpreted. The file is a dump from SSIS/SQL Server being read in by a Linux machine for processing.

• vi，less，more等内是否有任何开关?

• Are there any switches within vi, less, more, etc?

除了查看行尾，我还需要知道它是什么类型的行尾(CRLF或LF).我如何找到答案?

In addition to seeing the line-endings, I need to know what type of line end it is (CRLF or LF). How do I find that out?

推荐答案

您可以使用file实用工具来指示行尾的类型.

You can use the file utility to give you an indication of the type of line endings.

Unix:

$ file testfile1.txt
testfile.txt: ASCII text

"DOS":

$ file testfile2.txt
testfile2.txt: ASCII text, with CRLF line terminators

要从"DOS"转换为Unix:

To convert from "DOS" to Unix:

$ dos2unix testfile2.txt

要从Unix转换为"DOS":

To convert from Unix to "DOS":

$ unix2dos testfile1.txt

转换已转换的文件没有任何效果，因此尽管一如既往地适用通常的免责声明，但盲目运行(即不先测试格式)是安全的.

Converting an already converted file has no effect so it's safe to run blindly (i.e. without testing the format first) although the usual disclaimers apply, as always.
