从行显示整个单词

Question

我想只显示唯一的单词作为输出。如何定义grep表达式？

strings file.txt |grep (filter to display only whole words) | unique

Answer 1

cat file.txt | sed -e 's/\s\+/\n/g' | sort -u

Answer 2

听起来你需要翻译＆＃34;空白＆＃34;进入换行：

strings file.txt | tr '[:blank:]' '\n' | sort -u

Answer 3

这应该有效：

s="sample word sample word samples"
echo "$s" |grep -oE "\b\w+\b"|sort -u

输出：

sample
samples
word
