I have a bunch of directories. Inside these directories is a cover letter and a zip archive of work. I wanted to run a quick and easy query to open up all the cover letters so I can decide if it's worth looking at the work folder.find . | grep cover\.pdf | xargs open    #OS X has open linked to open the fileThis doesn't work. I've also muddied around with various print0, xargs -0 variations with little success. What's the proper way to do this? 
Help with a find command
osx;grep;find
