grep multiple patterns - find files containing multiple patterns

Linux grep FAQ: How can I use the grep command to search for multiple patterns with one command?

A little while ago I needed to search for all files in a CVS repository that contain multiple character patterns. That is, I wanted to be able to grep multiple patterns in multiple files. In my case the patterns I was looking for were the strings "prevayl" and "jtable".

grep multiple string patterns in many files

I couldn't find a way to do this with a simple combination of the find and grep commands, but a friend suggested this grep/find command combination:

grep -li "jtable" $(find . -name "*.java,v" -exec grep -li "prevayl" {} \;)

This find/grep command begins inside the parentheses by first finding all files whose name ends with the characters "*.java,v" and also contains the string "prevayl". Once it finds those files the find command prints the file names, and then the grep command at the beginning of the expression kicks in to find the string "jtable".

There may be better ways of doing this, but for today it worked as an okay solution to grep multiple patterns on many files, in many directories.

I just updated my Linux grep command examples, and it shows many other grep command examples that may also be helpful.
