Needs help in parsing comma separated values

Shell Programming and Scripting
1

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:

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:

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?

As you go through each iteration...the script needs to wipe out values that have been extracted from $jobKeys and $jobNames...this way your while will terminate instead of looping ad nauseum...
