Hi Motashims,

I've tried this on a couple of systems and get the following - for Solaris;

Code:

-bash-3.2$ cat arrtest.sh
IFS=' ' read -ra my_array <<< "2019-09-11 15:17:55 CR1234 anonymous       Deployed        DR_only        Back_APP"
#Print the split string
for i in "${my_array[@]}"
do
     echo $i
done
-bash-3.2$ ./arrtest.sh
2019-09-11
15:17:55
CR1234
anonymous
Deployed
DR_only
Back_APP
-bash-3.2$ uname -a
SunOS isd250 5.10 Generic_150400-46 sun4v sparc sun4v
-bash-3.2$ bash --version
GNU bash, version 3.2.52(1)-release (sparc-sun-solaris2.10)
Copyright (C) 2007 Free Software Foundation, Inc.
-bash-3.2$

And on a much later version of Red Hat;

Code:

[root@fbakirpomd4 bin]# cat arrtest.sh
IFS=' ' read -ra my_array <<< "2019-09-11 15:17:55 CR1234 anonymous       Deployed        DR_only        Back_APP"
#Print the split string
for i in "${my_array[@]}"
do
     echo $i
done
[root@fbakirpomd4 bin]# ./arrtest.sh
2019-09-11

[root@fbakirpomd4 bin]# cat /etc/redhat-release

I'm unable to replicate the issue - I think.

NAME

     libbash -- A bash shared libraries package.

DESCRIPTION

     libbash  is  a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may
     want to load and use in scripts of your own.

     It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries.

     Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1).  A bash shared library that can be  loaded
     using
     ldbash(1) must answer 4 requirments:

     1.     It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash).

     2.     It must contain a line that begins with '#EXPORT='.  That line will contain (after the '=') a list of functions that the library
	    exports.  I.e. all the function that will be usable after loading that library will be listed in that line.

     3.     It must contain a line that begins with '#REQUIRE='.  That line will contain (after the '=') a list of bash libraries that are
	    required for our library.  I.e. every bash library that is in use in our bash library must be listed there.

     4.     The library must be listed (For more information, see ldbashconfig(8)).

   Basic guidelines for writing library of your own:
     1.     Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions.

     2.     Try to declare all variables intended for internal use as local.

     3.     Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with:
		  __<library_name>_
	    For example, internal function myfoosort of hashstash library should be named as
		  __hashstash_myfoosort
	    This helps to avoid conflicts in global name space when using libraries that come from different vendors.

     4.     See html manual for full version of this guide.
