Viewing And Editing
===================

   To view a list of files that meet certain criteria, simply run your
file viewing program with the file names as arguments.  Shells
substitute a command enclosed in backquotes with its output, so the
whole command looks like this:

     less `find /usr/include -name '*.h' | xargs grep -l mode_t`

You can edit those files by giving an editor name instead of a file
viewing program.
