This isn\'t working. Can this be done in find? Or do I need to xargs?
find -name \'file_*\' -follow -type f -exec zcat {} \\| agrep -dEOE \'grep\' \\;
I found that running a string shell command (sh -c) works best, for example:
find -name 'file_*' -follow -type f -exec bash -c "zcat \"{}\" | agrep -dEOE 'grep'" \;
