i have a logfile which is continuously being updated. I have built a script to check for a specific content and if it is found, it sends a string into a file. Here's the current script:
As you can see i am continuously reading from the "server.log" file and while reading each entry, if the "grep" command find the matched string it echoes to file, else it echos to the same file but with a different string (YES or NO).
However i noticed that when the end of the day is reached, i.e @ 23:59, the file "/home/nms/Disconnection_oldstack.txt" stops updating. I noticed that the "server.log" file closes and a new one is reopened at that time, here below:
i tried to add
in the beginning of the script so it sleeps if file is does not exist (since i thought that at the time of the file rotation it stops since the file is not found), but the same thing happened.
Am i missing something?
Note: The output redirection to file is necessary in this case so i need to stick to that!

atf-sh
ATF-SH(1) BSD General Commands Manual ATF-SH(1)NAME
atf-sh [-s shell] -- interpreter for shell-based test programs
SYNOPSIS
atf-sh script
DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.
atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter-
preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not
use any non-standard extensions.
The following options are available:
-s shell Specifies the shell to use instead of the value provided by ATF_SHELL.
ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes.
ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes.
ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a
specific interpreter.
EXAMPLES
Scripts using atf-sh(3) should start with:
#! /usr/bin/env atf-sh
Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode
the path to atf-sh in the script and then use the -s option afterwards as a single parameter:
#! /path/to/bin/atf-sh -s/bin/bash
ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts.
