Hi Santiago, That is the expected/documented behavior. It was changed upstream 2.5 years ago (as seen in the NEWS file): * Noteworthy changes in release 2.11 (2012-03-02) [stable] ** Bug fixes ... ** New features If no file operand is given, and a command-line -r or equivalent option is given, grep now searches the working directory. Formerly grep ignored the -r and searched standard input nonrecursively. An -r found in GREP_OPTIONS does not have this new effect. -------------------- Note that GREP_OPTIONS has recently been deprecated, so this functionality will disappear. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
