grep for string "and" string in a file
Hi,
I am trying to look for two different strings in a file using an "AND" operator. For instance...

File 1.txt
woof
meow

File 2.txt
woof
bark

I want to do a search in the directory to give me the name of the file that contains both "woof" and "meow" on different lines. So in this example I would want the command to return "File 1.txt"

I tried..
grep "woof" | grep "meow" -H *.txt

This is doing an OR operation which is not what I want...and returns all the files that contain either "woof" or "meow"..

Any help is appreciated...

Try this:
Code:
grep -l woof *.txt | xargs grep -l meow

All text files are searched for woof and their names passed to xargs which invokes a grep for meow only on files that contain the word woof. The result of the second grep is the list of files that then contain both.
