How to find files with missing text

[bizshop]

Need to make sure a security line is added in to every webpage on a site, trying to find out how to list only the filenames of the pages that are missing the text.

awk or grep?

So what I want is to list all files NOT containing the word 'securemasthead'

use grep. -L is the option you want to use:

$ echo 'test1' > test1.txt
$ echo 'test2 securemasthead' > test2.txt
$ grep -L securemasthead *
test1.txt
$ grep -l securemasthead *
test2.txt

if you need to grep in a directory structure, also add -R option
