I'm trying to use grep to find a specific piece of text in a bunch of files on my web server. No problem, except that it returns way more information than I want! Ideally it would just return a list of files, and if the text exists in more than one place in the file it would only list the file name once. Currently I'm using something like this:grep -ir essay_ mysiteto do a case-insensitive recursive search for the word essay_ in all directories of my site. What it returns is something like this:mysite/dot/contest_declaration.php:$questions = $db->get_results(SELECT * FROM dot_essay WHERE active = 1 order by display_order asc);mysite/dot/contest_declaration.php:     $db->query(DELETE FROM dot_essay_xref WHERE entry_id = $svar_entry_id);mysite/dot/contest_declaration.php:     $id = $question->essay_id;mysite/dot/contest_declaration.php:     $answer = ${essay_$id};shoppermarketexpo/dot/print_declaration.php:        $questions = $db->get_results(SELECT * FROM dot_essay WHERE active = 1);What I'd like to get back is:mysite/dot/contest_declaration.phpmysite/dot/print_declaration.php
What params do I pass to grep to return only file names?
