I am looking for a global variable found_flag to be set a value that can be accessed outside the loop anywhere in the bash shell script.
Output: bash -x test.sh
In the RED BOLD output above I am expecting the found_flag to have the value=1 instead of zero.
Can you please suggest a quick way how I can set the value globally so it reflects outside the loop as well ?
Using sub-shells would be my last priority.

We run an RS/6000 SP Frame. One of the nodes running (AIX 5), in the frame, seems to run fine for a few weeks and then will no longer communicate with the outside world. I can not telnet to the server or ping the server.
This is true for both the ethernet and serial connection.

Hi Guys,
i have learned today that when you ftp a file with full write permissions (777) to another destination it loses the w options. so a file that was once -rwxrwxrwx(before FTP) is now -rw-r--r-- (after FTP). why does this happen? and is it configurable?

Simple enough problem I think, I just can't seem to get it right.
The below doesn't work as intended, it's just a function defined in a much larger script:
CheckValues() {
for field in \
Group_ID \
Group_Title \
Rule_ID \
Rule_Severity \

I have a simple script to log network connectivity to a set of systems.
However, as expected the date appended to the log never changes because the new variable is lost when the loop starts again. Can someone clue me in on how to get around this issue?

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.
