Search for specific file content

I would like to do a search to  list  all files that have a particular set of words contained in them, i.e., "digital brochures". I do not want it to be case sensitive.  I would like to do the search of all files in the current directory plus all its subdirectories.

Thank you.

grep -R -i -l "digital brochures" .

Note the dot " ." at the end!

The above will list just filenames with matching content, not the content itself. To see the content along with the filename, omit "-l".

Do you want the order specified as well like "digital brochures" or do you want all files that contain both words (anywhere in the file)?

No, I want it in that order for this purpose. For academic purposes, let's say I wanted it the way you suggested. How would the command be modified?

When I enter the command grep -R -i -l "digital brochures",  the cursor just seems to be stuck in one spot. Does this command take a long time to execute?

You forgot to type the dot "." at the end. See the note in my first comment!

To your academic question:

grep -E -R -i -l "digital|brochures" .

"-E" means "Interpret the pattern as an extended regular expression", and
the vertical bar ("pipe") means "or".

Depending on how much files you have, yes it can...

grep -iR -l "digital" . 2>/dev/null | xargs grep -iR -l "brochures" 2>/dev/null
