逐字阅读整个文本文件与bash排序的单词

Question

假设我的文件test.txt包含内容：

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam rhoncus dictum eros, eu molestie lectus cursus sit amet. Aliquam lectus erat, ultricies sit amet venenatis et, tincidunt eget magna.

我需要的是，逐字读取整个文件，但是......按字词排序。所以：

Aliquam
Aliquam
consectertur
dictum
...

任何想法？

Answer 1

tr ' ' '\n' < test.txt | sort -u

如果您需要重复项，请删除-u

Answer 2

for w in `cat test.txt`; do echo "$w"; done | sort

删除标点符号：

for w in `cat test.txt`; do echo "$w"; done | sed 's,[^a-zA-Z],,g' | sort

Answer 3

tr "[[:space:]]" "\n" < file| sed 's/[[:punct:]]$//' | sort
