如何让猫开始一个新行 [英] How to make cat start a new line

问题描述

我有四个文件：

one_file.txt

one_file.txt

abc | def

two_file.txt

two_file.txt

ghi | jkl

three_file.txt

three_file.txt

mno | pqr

four_WORD.txt

four_WORD.txt

xyz| xyz

我想连接所有文件file.txt（即所有除four_WORD.txt）结尾的文件中，以获得：

I want to concatenate all of the files ending with "file.txt" (i.e. all except four_WORD.txt) in order to get:

abc | def
ghi | jkl
mno | pqr

要做到这一点，我运行：

To accomplish this, I run:

猫* file.txt的> full_set.txt

cat *file.txt > full_set.txt

不过，full_set.txt出来的：

However, full_set.txt comes out as:

abc | defmno | pqrghi | jkl

任何想法如何正确有效地做到这一点，使每一个在其自己的行结束了？在现实中，我需要做的上面有很多非常大的文件。预先感谢您的帮助。

Any ideas how to do this correctly and efficiently so that each ends up on its own line? In reality, I need to do the above for a lot of very large files. Thank you in advance for your help.

推荐答案

尝试：

awk 1 *file.txt > full_set.txt

这是低效率的，一个的裸的猫，但会增加一个额外的 \\ n 如果在每个文件的结尾缺失

This is less efficient that an bare cat but will add an extra \n if missing at the end of each file
