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?

mfontset_lookup

mfontset_lookup(3m17n)						 The m17n Library					    mfontset_lookup(3m17n)

NAME

       mfontset_lookup - Lookup a fontset.

SYNOPSIS

       MPlist * mfontset_lookup (MFontset * fontset, MSymbol script, MSymbol language, MSymbol charset)

DESCRIPTION

       Lookup a fontset. The mfontset_lookup() function lookups fontset and returns a plist that describes the contents of fontset corresponding
       to the specified script, language, and charset.

       If script is Mt, keys of the returned plist are script name symbols for which some fonts are specified and values are NULL.

       If script is a script name symbol, the returned plist is decided by language.

       o If language is Mt, keys of the plist are language name symbols for which some fonts are specified and values are NULL. A key may be Mt
	 which means some fallback fonts are specified for the script.
       o If language is a language name symbol, the plist is a FONT-GROUP for the specified script and language.  FONT-GROUP is a plist whose keys
	 are FLT (FontLayoutTable) name symbols (Mt if no FLT is associated with the font) and values are pointers to MFont.
       o If language is Mnil, the plist is fallback FONT-GROUP for the script.
       If script is Mnil, the returned plist is decided as below.
       o If charset is Mt, keys of the returned plist are charset name symbols for which some fonts are specified and values are NULL.
       o If charset is a charset name symbol, the plist is a FONT-GROUP for the charset.
       o If charset is Mnil, the plist is a fallback FONT-GROUP.
RETURN VALUE

	   It returns a plist describing the contents of a fontset. The plist should be freed by m17n_object_unref().
