问题描述
我正在尝试使用AWK将文本文档中的每个单词放在新行上.我真的不知道如何使用AWK，但是我在网上找到了一些可以解决我问题的命令.我尝试了以下命令:
I'm trying to use AWK to place every word within a text document on a new line. I don't really know how to use AWK but I've found some commands online which should solve my problem. I've tried the following commands:
$ awk '{ for (i = 1; i <= NF; i++) print $i }' input.txt > output.txt
和
$ awk '{c=split($0, s); for(n=1; n<=c; ++n) print s[n] }' input.txt > output.txt
但是，这两个命令都具有相同的效果，即删除了所有空格.
However, both of these commands have the same effect, which is that all spaces are removed.
为清楚起见，可以说input.txt包含以下文本:
For clarity, lets say that input.txt contains the text:
The fox jumped over the dog
output.txt应包含:
output.txt should contain:
The
fox
jumped
over
the
dog
但是output.txt包含:
However output.txt contains:
Thefoxjumpedoverthedog
我正在Windows 7上使用Cygwin来使用这些命令.命令中是否缺少某些内容?
I'm using Cygwin on Windows 7 to use these commands. Is there something I'm missing within the commands?
推荐答案
根据联机帮助页，awk中的print打印其参数:
According to the manpage, print in awk prints its arguments:
因此您的第一个命令是可以的，但是您需要确保输出记录分隔符是新行.默认的输出记录分隔符是换行符，但请尝试确保:
So your first command is ok, but you need to make sure your output record separator is a new line. The default output record separator is a newline, but try making sure:
awk -v ORS='\n' '{ for (i = 1; i <= NF; i++) print $i }' input.txt > output.txt
仅在Cygwin上，您可能会遇到Windows/DOS行尾的问题.也尝试ORS='\r\n'.或者，将输出通过unix2dos传递给管道.
On Cygwin only, you might be running into issue with Windows/DOS line endings. Try also ORS='\r\n'. Alternatively, pipe the output through unix2dos.
