z naszego manuala:

    Grep   understands  two   different   versions  of   regular
    expression  syntax: "basic"  and  "extended."  In GNU  grep,
    there  is no  difference  in  available functionality  using
    either  syntax.  In  other  implementations,  basic  regular
    expressions are  less power­ ful. The  following description
    applies to  extended regular expressions; differ­  ences for
    basic regular expressions are summarized afterwards.
