   Thanks, your post led me to...   
      
   How can I search a file to see if it contains multiple patterns anywhere   
   in the file?

   It can be done using multiple grep commands. Read man grep xargs, and do   
   something like   
      
   grep -l 'pattern1' -f filelist | \   
        xargs grep -l 'pattern2` | \   
        xargs grep -l 'pattern3'   
      
   The first grep produces a list of files containing the first pattern.   
   The second (xargs grep) searches for the second pattern in the files   
   containing the first pattern.
