Can you copy/paste what you're seeing? As long as you run it from the
WordPress docroot, and the plugins/themes folder locations haven't been
customized, it should look something like this but with matches from grep:

'sm_type|is_unique|connect_hash|reqType' wp-content/{plugins,themes}
root at aviator [/home/gog/public_html]#
