How To Read a File and Assign the line values to an Array?
i have this basic code that i wrote to read a file and place it's values to an array. the source/input file will have multiple strings on it that is separated by a whitespace.

sample_list.txt file contents:
Code:
ACCT1 TABLE1
ACCT2 TABLE2
ACCT3 TABLE3


script file: sample_list.sh
Code:
#!/bin/bash

vFileDir="sample_list.txt"

declare -a vLnArray

printf " \n"
#read the content of the file by line
while IFS= read vline
do
 vLnArray=("$vline")
 vStr1="${vLnArray[0]}"
 vStr2="${vLnArray[1]}"

 echo "vStr1: $vStr1"
 echo "vStr2: $vStr2"

 vLnCtr=$((vLnCtr+1))
done < "$vFileDir"


when i run the script it gives me this output:
Code:
vStr1: ACCT1 TABLE1
vStr2:
vStr1: ACCT2 TABLE2
vStr2:
vStr1: ACCT3 TABLE3
vStr2:


basically this is the expected output:
Code:
vStr1: ACCT1 
vStr2: TABLE1
vStr1: ACCT2 
vStr2: TABLE2
vStr1: ACCT3 
vStr2: TABLE3


please help thank you.

gensprep

gensprep(8)							 ICU 50.1.2 Manual						       gensprep(8)

NAME

       gensprep - compile StringPrep data from files filtered by filterRFC3454.pl

SYNOPSIS

       gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s, --sourcedir source ] [ -d, --destdir destination ]

DESCRIPTION

       gensprep reads filtered RFC 3454 files and compiles their information into a binary form.  The resulting file, <name>.icu, can then be read
       directly by ICU, or used by pkgdata(8) for incorporation into a larger archive or library.

       The files read by gensprep are described in the FILES section.

OPTIONS

       -h, -?, --help
	      Print help about usage and exit.

       -v, --verbose
	      Display extra informative messages during execution.

       -c, --copyright
	      Include a copyright notice into the binary data.

       -s, --sourcedir source
	      Set the source directory to source.  The default source directory is specified by the environment variable ICU_DATA.

       -d, --destdir destination
	      Set the destination directory to destination.  The default destination directory is specified by the environment variable ICU_DATA.

ENVIRONMENT

       ICU_DATA  Specifies the directory containing ICU data. Defaults to /usr/share/icu/50.1.2/.  Some tools in ICU depend on the presence of the
		 trailing slash. It is thus important to make sure that it is present if ICU_DATA is set.

FILES

       The  following files are read by gensprep and are looked for in the source /misc for rfc3454_*.txt files and in source /unidata for Normal-
       izationCorrections.txt.

       rfc3453_A_1.txt	   Contains the list of unassigned codepoints in Unicode version 3.2.0....

       rfc3454_B_1.txt	   Contains the list of code points that are commonly mapped to nothing....

       rfc3454_B_2.txt	   Contains the list of mappings for casefolding of  code points when Normalization form NFKC is specified....

       rfc3454_C_X.txt	   Contains the list of code points that are prohibited for IDNA.

       NormalizationCorrections.txt
			   Contains the list of code points whose normalization has changed since Unicode Version 3.2.0.
