Confused with grep for multiple words
Hi guys and gals,

I have many files that contains many lines of data. I am trying to find a needle in a haystack in that I'm looking only for files that contain word1 AND word2.

I'm using ...

Quote:
egrep -l 'word1|word2'
...

but this is finding files that contains word1 OR word2. No good for me. How can I grep to find both words in a single file?

Thanks in advance.

Code:
 awk '{if(f!=FILENAME){f=FILENAME;d=1}}/word1/&&d{p=1}/word2/&&d{q=1}p&&q&&d{print f;d=p=q=0}' input_files

So, this will print the file names once if word1 and word2 is found in any order.

Here is an alternate way:
Code:
grep -l word1 files.* > file_list
grep -l word2 files.* >> file_list
sort file_list | uniq -c | grep " 2 "

Nice one. Smilie That's a little more complicated than I was expecting. Will give it a go.

Thanks.

What does the " 2 " do in this?

file_list will have file names which contain both word1 and word2 . i.e. if the file has both word1 and word2, then that file name will be present 2 times in the file_list.
uniq will give the count. So if the count is 2 or more, then it means both the words are present.

Code:
grep -w word1 files* > out1

-w option for searching the word
