When I user “tail –f FILENAME” to follow a file, which is continually growing, the output sometimes stops. When I press ctrl-c to quit and right immediately follow the same file, output would continue. And I found the file is growing while the output stops.

(BTW, it’s a log file with timestamp, so I am sure the file is growing. And while writing this mail, the file in another window stops, again.)

Maybe it is a bug, or not. Please explain this for me.

In private mails, the user confirmed that the file is being renamed, and thus -F is required. cheers, Pádraig. ------------=_1326102602-6744-1 Content-Type: message/rfc822 Content-Disposition: inline Content-Transfer-Encoding: 7bit Received: (at submit) by debbugs.gnu.org; 6 Jan 2012 07:43:17 +0000 Received: from localhost ([127.0.0.1] helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.69) (envelope-from ) id 1Rj4SL-0004MI-BB for submit@debbugs.gnu.org; Fri, 06 Jan 2012 02:43:17 -0500 Received: from eggs.gnu.org ([140.186.70.92]) by debbugs.gnu.org with esmtp (Exim 4.69) (envelope-from ) id 1Rj4JZ-00047b-Mu for submit@debbugs.gnu.org; Fri, 06 Jan 2012 02:34:15 -0500 Received: from Debian-exim by eggs.gnu.org with spam-scanned (Exim 4.71) (envelope-from ) id 1Rj4G5-0002hA-Db for submit@debbugs.gnu.org; Fri, 06 Jan 2012 02:30:38 -0500 X-Spam-Checker-Version: SpamAssassin 3.3.2 (2011-06-06) on eggs.gnu.org X-Spam-Level: X-Spam-Status: No, score=-4.2 required=5.0 tests=BAYES_00,HTML_MESSAGE, RCVD_IN_DNSWL_MED, T_RP_MATCHES_RCVD autolearn=unavailable version=3.3.2 Received: from lists.gnu.org ([140.186.70.17]:53130) by eggs.gnu.org with esmtp (Exim 4.71) (envelope-from ) id 1Rj4G5-0002h6-C6 for submit@debbugs.gnu.org; Fri, 06 Jan 2012 02:30:37 -0500 Received: from eggs.gnu.org ([140.186.70.92]:41343) by lists.gnu.org with esmtp (Exim 4.71) (envelope-from ) id 1Rj4G4-00022k-2W for bug-coreutils@gnu.org; Fri, 06 Jan 2012 02:30:37 -0500 Received: from Debian-exim by eggs.gnu.org with spam-scanned (Exim 4.71) (envelope-from ) id 1Rj4G2-0002eZ-OY for bug-coreutils@gnu.org; Fri, 06 Jan 2012 02:30:36 -0500 Received: from szxga04-in.huawei.com ([119.145.14.67]:35981) by eggs.gnu.org with esmtp (Exim 4.71) (envelope-from ) id 1Rj4G2-0002VS-AM for bug-coreutils@gnu.org; Fri, 06 Jan 2012 02:30:34 -0500 Received: from huawei.com (szxga04-in [172.24.2.12]) by szxga04-in.huawei.com (iPlanet Messaging Server 5.2 HotFix 2.14 (built Aug 8 2006)) with ESMTP id <0LXD004428S3RN@szxga04-in.huawei.com> for bug-coreutils@gnu.org; Fri, 06 Jan 2012 15:28:51 +0800 (CST) Received: from szxrg01-dlp.huawei.com ([172.24.2.119]) by szxga04-in.huawei.com (iPlanet Messaging Server 5.2 HotFix 2.14 (built Aug 8 2006)) with ESMTP id <0LXD007758S36K@szxga04-in.huawei.com> for bug-coreutils@gnu.org; Fri, 06 Jan 2012 15:28:51 +0800 (CST) Received: from szxeml206-edg.china.huawei.com ([172.24.2.119]) by szxrg01-dlp.huawei.com (MOS 4.1.9-GA) with ESMTP id AGG35428; Fri, 06 Jan 2012 15:27:51 +0800 Received: from SZXEML409-HUB.china.huawei.com (10.82.67.136) by szxeml206-edg.china.huawei.com (172.24.2.58) with Microsoft SMTP Server (TLS) id 14.1.323.3; Fri, 06 Jan 2012 15:27:48 +0800 Received: from SZXEML519-MBS.china.huawei.com ([169.254.7.136]) by szxeml409-hub.china.huawei.com ([10.82.67.136]) with mapi id 14.01.0323.003; Fri, 06 Jan 2012 15:27:43 +0800 Date: Fri, 06 Jan 2012 07:27:42 +0000 From: yukuan Subject: maybe a bug for "tail" X-Originating-IP: [10.138.12.174] To: "bug-coreutils@gnu.org" Message-id: <3ECE7663C0562F4FA7C918B9A030A10928D1A62B@SZXEML519-MBS.china.huawei.com> MIME-version: 1.0 Content-type: multipart/alternative; boundary="Boundary_(ID_UfZL6du6DIohE6Vjz5wF1Q)" Content-language: zh-CN Accept-Language: zh-CN, en-US Thread-topic: maybe a bug for "tail" Thread-index: AczMRKvXOG/kCOY2SLesNnZBUzmFEA== X-MS-Has-Attach: X-MS-TNEF-Correlator: X-CFilter-Loop: Reflected X-detected-operating-system: by eggs.gnu.org: Solaris 9 X-detected-operating-system: by eggs.gnu.org: GNU/Linux 2.6 (newer, 3) X-Received-From: 140.186.70.17 X-Spam-Score: -6.0 (------) X-Debbugs-Envelope-To: submit X-Mailman-Approved-At: Fri, 06 Jan 2012 02:43:16 -0500 X-BeenThere: debbugs-submit@debbugs.gnu.org X-Mailman-Version: 2.1.11 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: debbugs-submit-bounces@debbugs.gnu.org Errors-To: debbugs-submit-bounces@debbugs.gnu.org X-Spam-Score: -6.0 (------) --Boundary_(ID_UfZL6du6DIohE6Vjz5wF1Q) Content-type: text/plain; charset=us-ascii Content-transfer-encoding: 7BIT When I user "tail -f FILENAME" to follow a file, which is continually growing, the output sometimes stops.

When I user “tail –f FILENAME” to follow a file, which is continually growing, the output sometimes stops. When I press ctrl-c to quit and right immediately follow the same file, output would continue. And I found the file is growing while the output stops.

(BTW, it’s a log file with timestamp, so I am sure the file is growing. And while writing this mail, the file in another window stops, again.)

Maybe it is a bug, or not. Please explain this for me.

Thanks!
