Needs help in parsing comma separated values
hello experts,

i am retrieving values in variables jobKey and jobName within my shell script. these values are returned to me within braces [ ] and i am using following command to remove those braces:

Code:
jobKeys=`echo $jobKeys | sed 's:^.\(.*\).$:\1:'` 
jobNames=`echo $jobNames | sed 's:^.\(.*\).$:\1:'`

if there are two jobs my jobKeys and jobName variables consist comma separated values like

jobKeys=key-43321-4, key-99838-7
jobNames=job1, job2

I want to write a loop based on these variable values so that when the loops runs first time i should get following values in my variables:

jobKey=key-43321-4 and jobName=job1

and when loop runs second time my variable should have

jobKey=key-99838-7 and jobName=job2

I tried below but it goes into infinite loop:

Code:
while [[ -z ${jobKeys} && -z ${jobNames} ]] 
                        do 
                                        jobKey=`echo ${jobKeys} | cut -d, -f$i` 
                                        echo " " 
                                        echo "$jobKey" 
                                        jobName=`echo ${jobNames} | cut -d, -f$i` 
                                        echo " " 
                                        echo "$jobName" 
                                        i=`expr $i  + 1` 
                        done

any ideas what my loop should look like?

vconsole.conf

VCONSOLE.CONF(5)                                                   vconsole.conf                                                  VCONSOLE.CONF(5)

NAME

       vconsole.conf - configuration file for the virtual console

SYNOPSIS

       /etc/vconsole.conf

DESCRIPTION

       The /etc/vconsole.conf file configures the virtual console, i.e. keyboard mapping and console font.

       The basic file format of the vconsole.conf is a newline-separated list environment-like shell-compatible variable assignments. It is
       possible to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported,
       allowing applications to read the file without implementing a shell compatible execution engine.

       Note that the kernel command line options vconsole.keymap=, vconsole.keymap.toggle=, vconsole.font=, vconsole.font.map=,
       vconsole.font.unimap= may be used to override the console settings at boot.

       Depending on the operating system other configuration files might be checked for configuration of the virtual console as well, however only
       as fallback.

OPTIONS

       The following options are understood:

       KEYMAP=, KEYMAP_TOGGLE=
           Configures the key mapping table of for they keyboard.  KEYMAP= defaults to us if not set. The KEYMAP_TOGGLE= can be used to configured
           a second toggle keymap and is by default unset.

       FONT=, FONT_MAP=, FONT_UNIMAP=
           Configures the console font, the console map and the unicode font map.  FONT= defaults to latarcyrheb-sun16.

EXAMPLE

       Example 1. German keyboard and console

       /etc/vconsole.conf:

           KEYMAP=de-latin1
           FONT=latarcyrheb-sun16
