grep 逻辑与

jazeltq

请问如何用grep实现逻辑与的查找功能？
比如
我想查找  *.xxx  中含有  description   和  value 两个单词的行
我试过
grep -e "description" -e "value" *.xxx  这是个逻辑或
到不到要求哈，
哪位知道， 说一下，谢了

jerryjzm

grep -E "description|value"
or
egrep "description|value"

jazeltq

no, you misunderstand me .
I got the answer in a foreign website
It is
grep -E "patten1.*pattem2" filename

And the answere you give me can implement OR fuction, which is not my want.

jazeltq

for others, may it can help someone in the same trap

grep 'first pattern.*second pattern' foofile

This will not find lines where the 2nd pattern precedes the 1st one.

But this will:

egrep '1st pattern.*2nd pattern|2nd pattern.*1st pattern' foofile

taojie2000

egrep '1st pattern.*2nd pattern|2nd pattern.*1st pattern' foofile
或
grep 1st pattern  file | grep 2nd pattern

sorry，题干都没看清就回答，审题不清
那这个简单，grep是支持正则表达式的

grep "description[空格].*[空格]value"

法一、egrep 'description.*value|value.*description'  *.xxx

法二、grep description *.xxx|grep value
