Hi:

I found a problem of tail –F in centos 6.7. The = kernel version is 2.6.32-642.3.1.el6. I execute “tail -f = --follow=3Dname --max-unchanged-stats=3D50 --sleep-interval=3D1 = ./t” in a terminal and execute echo command to append some content = to file t. then I execute “mv t t1”, the “tail = –f ” show error message of “no such file t” = immediately.

The parameter of “--max-unchanged-stats” seems = to have no effect. But in centos 5.6, things is different. The parameter = of “--max-unchanged-stats” take effect. So I want to know = the reason. Thank you.

Hi, Since the inotify implementation, --max-unchanged-stats is ineffective, and this is indicated in the man page in the description of that option. thanks, Pádraig From debbugs-submit-bounces@debbugs.gnu.org Sun Oct 28 22:40:01 2018 Received: (at control) by debbugs.gnu.org; 29 Oct 2018 02:40:01 +0000 Received: from localhost ([127.0.0.1]:49565 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1gGxTF-00005K-6k for submit@debbugs.gnu.org; Sun, 28 Oct 2018 22:40:01 -0400 Received: from mail-it1-f180.google.com ([209.85.166.180]:36871) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1gGxTD-00004y-6J for control@debbugs.gnu.org; Sun, 28 Oct 2018 22:39:59 -0400 Received: by mail-it1-f180.google.com with SMTP id e74-v6so7754581ita.2 for ; Sun, 28 Oct 2018 19:39:59 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025; h=to:from:message-id:date:user-agent:mime-version:content-language :content-transfer-encoding; bh=7XppfaQKr7szspn22o1ZtxbhUHAQU1yWVZ4MX05qOJI=; b=KxmDYVPWQWKSd7XuMTpmF7BZDBqebM9kS15/KwV67AxuyHdH0UomYh1X3GZEftGqgX tnU3AXWpFGbhteQBb6eEt/4aa46YcNcLKbYWzD0fJ3V1lOtvjUt3Beuc3l7DD7TYEISd N7EsugTE0ZBm/im2z4XCAkzxQ9Qk5RauREOGN8MbE9TNAnEdykGIgQo2N0IjKnvJFQEp +FDZ/GhXAGhHDSDr/mUo4j/D6OMjRlNF73Eu00hGbrCd3PIeuM1MtirwNmV3pUBnFjdU qns+9NUI6r0zGxMRBQtRakWDUMWujvAHzfy5bx0/V0HD+GaChQ4MXQBmAMttafbd1XwV kbFQ== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:to:from:message-id:date:user-agent:mime-version :content-language:content-transfer-encoding; bh=7XppfaQKr7szspn22o1ZtxbhUHAQU1yWVZ4MX05qOJI=; b=HCFg2fDdStOFcHCp+EDqpbHaLfqyUgBAO1p9l+ZsOlApqbsLIabY550EEUhadshRu3 9WZEAVSYoo9+BQarwP+2lnd+R62xnN4fMXmK0gtLuA5+IN2dfiS+3qCGrBM6sWj/lzsP Yh/Vzj2h3OCNBhnAIa9/AiTkFDYhUa6ULrC44JsMYLkOVPmTA9/aMV6l9MJFOJ/0oiYT VVLadmnTd7eBeNFcuHJu/8CcaHYc7tXpUNj3diMXiPgTjzSjWqCthTAET5gccdazB3UP XOmAAO8GLnYdGohAmIbx1aLtJS/I9J87Oy2CANDCHgktrQhWu7m2JLLLTA0ysvGWlKCE HOAQ== X-Gm-Message-State: AGRZ1gLiiHhqsIdg+6gSbXzN39CcLtz8FynfLkNEMTGWhg2PvCrfkaKY 5cX/Cm+Xgii8fnhA+V2K4iYv9FPVADw= X-Google-Smtp-Source: AJdET5fLLFXZeuM7laFPndSQ/QxzLyO8Bmt3HamH4WMzDHZ53HAZG40QR8Rv1hhoNXTh/YGM5kgppA== X-Received: by 2002:a24:c301:: with SMTP id s1-v6mr3915783itg.151.1540780793033; Sun, 28 Oct 2018 19:39:53 -0700 (PDT) Received: from tomato.housegordon.com (moose.housegordon.com.
