Hello,

I could repeatedly reproduce an unexpected behaviour on several Linux systems (two installations of Arch Linux [newest state], a Debian [8.7] and a Ubuntu [16.4]).

I ran the following command - when I first ran it, it was accidentially

ps ax | grep -reh

I wanted to grep for processes containing the string "-reh", but forgot the "-e" which was necessary due to the leading dash in the string.

On all systems, grep outputs hundreds of (not even matching) lines from files of my home directory, not at all related to the output of ps, which I piped into grep.

Maybe, the command line is interpreted as:

* r ... search files recursively in directories. Note, that input is read from stdin here.

* e ... use the following pattern

* h ... this is the pattern expected by "e"

It may be that all the lines ouput by grep contain "h".

Although expected to be identical, this command works as expected:

ps ax | grep -reh /dev/stdin
Kind regards,

rexkogitans

That is, 'grep -r PAT' is equivalen to 'grep -r PAT .'. This is for convenience: as it does not make sense to use -r on an input stream, the default input is '.' instead of '-' when -r is used. grep cannot "know" that the user wanted it to read from stdin, for the same reason that it does not "know" that the user wanted it to read from stdin here: ps ax | grep 0:00 xyz This causes 'grep' to read from the file 'xyz', instead of the desired behavior of looking for the pattern '0:00 xyz' in the 'ps ax' output. The 'ps ax' output is ignored. ------------=_1486506723-19943-1 Content-Type: message/rfc822 Content-Disposition: inline Content-Transfer-Encoding: 7bit Received: (at submit) by debbugs.gnu.org; 7 Feb 2017 20:31:10 +0000 Received: from localhost ([127.0.0.1]:59325 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1cbCPt-0002Oh-Vu for submit@debbugs.gnu.org; Tue, 07 Feb 2017 15:31:10 -0500 Received: from eggs.gnu.org ([208.118.235.92]:37892) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1cbCJo-0002EB-KI for submit@debbugs.gnu.org; Tue, 07 Feb 2017 15:24:53 -0500 Received: from Debian-exim by eggs.gnu.org with spam-scanned (Exim 4.71) (envelope-from ) id 1cbCJi-0006kp-9x for submit@debbugs.gnu.org; Tue, 07 Feb 2017 15:24:47 -0500 X-Spam-Checker-Version: SpamAssassin 3.3.2 (2011-06-06) on eggs.gnu.org X-Spam-Level: * X-Spam-Status: No, score=1.3 required=5.0 tests=BAYES_50,FREEMAIL_FROM, HTML_MESSAGE,RCVD_IN_SORBS_SPAM autolearn=disabled version=3.3.2 Received: from lists.gnu.org ([2001:4830:134:3::11]:33307) by eggs.gnu.org with esmtps (TLS1.0:RSA_AES_256_CBC_SHA1:32) (Exim 4.71) (envelope-from ) id 1cbCJi-0006ki-76 for submit@debbugs.gnu.org; Tue, 07 Feb 2017 15:24:46 -0500 Received: from eggs.gnu.org ([2001:4830:134:3::10]:57080) by lists.gnu.org with esmtp (Exim 4.71) (envelope-from ) id 1cbCJg-0003fM-SS for bug-grep@gnu.org; Tue, 07 Feb 2017 15:24:46 -0500 Received: from Debian-exim by eggs.gnu.org with spam-scanned (Exim 4.71) (envelope-from ) id 1cbCJc-0006bq-2Z for bug-grep@gnu.org; Tue, 07 Feb 2017 15:24:44 -0500 Received: from mout.gmx.net ([212.227.17.22]:56925) by eggs.gnu.org with esmtps (TLS1.0:DHE_RSA_AES_256_CBC_SHA1:32) (Exim 4.71) (envelope-from ) id 1cbCJb-0006ZN-Mj for bug-grep@gnu.org; Tue, 07 Feb 2017 15:24:40 -0500 Received: from [141.201.229.148] ([141.201.229.148]) by mail.gmx.com (mrgmx103 [212.227.17.168]) with ESMTPSA (Nemesis) id 0LpsmR-1byZqY3RDT-00fgKQ for ; Tue, 07 Feb 2017 21:24:34 +0100 To: bug-grep@gnu.org From: "rexkogitans@gmx.at" Subject: Weird output of random files Message-ID: <5feb1e32-16f9-f9a4-b8ee-329958682622@gmx.at> Date: Tue, 7 Feb 2017 21:24:32 +0100 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Thunderbird/45.6.0 MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="------------F515E85000731D8AE6D81DED" X-Provags-ID: V03:K0:IiPbn2ZLDHZdntT2x/4TGq/zWhwVSgSogkhgmS8NFWtkesAmJX4 mBX1z3Au3e/5eLfujVRbujZTWAEiMl35ROS3Cn8qkNny+PKZ4EdhQrY4XgikLgxVfayoX9+ GEs6jHxMQYDGjuxxuxZPEDvRQ9Eerxs44TSQKCmtGsrlKFvYSkoA5lc2E42o4rWAeFmwsR9 ZRLhFdf8r5t76y1nzp3HA== X-UI-Out-Filterresults: notjunk:1;V01:K0:9/Ut4HlpZjU=:p31zrX/7Et9gl8S0Mowek1 eZWx8IFb8M5FgB4ktxgNxV5Ku3ryd81YoOYx03rqbLak8IebGiFMDRTr5OeMxDZ6z8lEpHbT0 nEiJJHCY+8053cJ5FswJkbWaffXBvZSGZ2xd1v6cY7AqhwBulm1yx2pPIPjN1Aks4jR32vwP8 +Vrs0dWfUCydBdZbl5aNH9PFiwkjdGB4kmCoZidA/tKpup+WiuHEixhenfnDh70YA2wVcd9j3 5ds854vNqiR1MHIOsRoZJWm7RJd4aO7huA/gC+CNrz+Zd/bf+s5oGa8Di/9rhS7wVdNi64uTO 7GgBlQhQxz/+S2k040Jozgyk5RmTe7ozpyOZPsMkOJqtgofjDV6ejoUpdBB7jPEScIlVwVxPI tsGaM4THvmicxKozDL+/mHw7+am4wFtS3KsRgZFGNeD7excoasds3t64d/az8ECSFl7THYXjQ 82waJvAjVmHCRgRWfOb+is7v3s+w9WVp9d8swAEBsD9z6dKbvVcTbKHcYngw8HLgppX7/lanD ivS7VTeG4gTHvyfTSszxSdYBGBwdEKDSb3popyGiDIAf4Em5lcKepRMfgs/qQVvTrl6MSavFQ bUDdNoSCH5pt47wiJXhZHPEOZA6pCd7yH5Jhsfpuuy99DCxEyxnrQy5ym8iOaCcAwbsY/mwdd KqJEv94TP0E+E1DnwYM7sk80GFaw91rMqCYA0twqSi8jBvcCtwOMJfZDYzk4vciKV2RxmrxvE b6jMKw7MvGAP3pcV+hBeeiTMiEh0zu861BxBnK9c1NRHmaktsJj6R26CZyOINrMKNQ/NmjNFL uDifrZ6w+BdDEPwMhQOhXrzP+T4Oa2tDtxSPu5LcCMqr0jlIdjgSHe4LkOjcbMbfPmCkT7g+w 1jllf2teU0rQzpHAQluWvU9DZRyEo2ZohchmXX3bba+0FIeDNbft+XipIcYAOKWYU4HLT+fb5 q05U9+Iuk+J524vQPhE0KmYbzX1Nqbu2NEA/hph2krdVdubyneuqbnagT6x7+roUKQkXSndOO 1CkjWOVAFaLv5aXHLiX0uY4= X-detected-operating-system: by eggs.gnu.org: GNU/Linux 2.2.x-3.x [generic] [fuzzy] X-detected-operating-system: by eggs.gnu.org: GNU/Linux 2.6.x X-Received-From: 2001:4830:134:3::11 X-Spam-Score: -3.6 (---) X-Debbugs-Envelope-To: submit X-Mailman-Approved-At: Tue, 07 Feb 2017 15:31:08 -0500 X-BeenThere: debbugs-submit@debbugs.gnu.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: debbugs-submit-bounces@debbugs.gnu.org Sender: "Debbugs-submit" X-Spam-Score: -3.6 (---) This is a multi-part message in MIME format. --------------F515E85000731D8AE6D81DED Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hello, I could repeatedly reproduce an unexpected behaviour on several Linux systems (two installations of Arch Linux [newest state], a Debian [8.7] and a Ubuntu [16.4]).

Hello,

I could repeatedly reproduce an unexpected behaviour on several Linux systems (two installations of Arch Linux [newest state], a Debian [8.7] and a Ubuntu [16.4]).

I ran the following command - when I first ran it, it was accidentially

ps ax | grep -reh

I wanted to grep for processes containing the string "-reh", but forgot the "-e" which was necessary due to the leading dash in the string.

On all systems, grep outputs hundreds of (not even matching) lines from files of my home directory, not at all related to the output of ps, which I piped into grep.

Maybe, the command line is interpreted as:

* r ... search files recursively in directories. Note, that input is read from stdin here.

* e ... use the following pattern

* h ... this is the pattern expected by "e"

It may be that all the lines ouput by grep contain "h".

Although expected to be identical, this command works as expected:

ps ax | grep -reh /dev/stdin
Kind regards,

rexkogitans

Hello, Paul,

this is= correct, it is mentioned in grep --help. However, I always expect the man = pages to be more exhaustive. But here, it only says

grep searches the named input FILEs for lines containing a match to the g= iven PATTERN.  If no files are specified, or if the file =E2=80= =9C-=E2=80=9D is given, grep  searches  standard &= nbsp;input.   By
default, grep prints the matching= lines.

Well, of course, in the description of --r= ecursive, it is mentioned:

    = ;  -r, --recursive
      =         Read  all files u= nder each directory, recursively, following symbolic links only if
            &= nbsp; they are on the command line.  Note that if no file op= erand is given, grep searches
      = ;        the working directory.&nbs= p; This is equivalent to the -d recurse option.

This could be made a bit more consistent.

= grep searches the named input FILEs for lines containing a match to the giv= en PATTERN.  If no files are specified, or if the file =E2=80=9C-= =E2=80=9D is given, grep  searches  standard  = ;input or, by using the --recursive switch, the current directory. =   By default, grep prints the matching lines.

If I am the first in the world to fall for this,= then please consider this discussion as useless. This bug report is closed= , anyway.

Kind regards,
