  65 Usage: vifiles [-R] [FILES]
  66 Options:
  67  -R, -r, --recursive    open all files within the directories specified in parameters
  68  -f, --force            don't ask confirmation to save changes (provided that the editor exited without error code)
  69
  70 vifiles opens up your text editor (search list: \$EDITOR, \$VISUAL, vi) to edit a file with the content of all of the files specified in parameters, each line prefixed with the file name from which it's coming from. Save changes back to the original files."
