here is a case-blind compare function for shell
Code:
#/bin/ksh
stricmp()
{
    let retval=0
    one="$( echo "$1" | tr -s '[:upper:]' '[:lower]')"
    two="$( echo "$2" | tr -s '[:upper:]' '[:lower]')"
    if [[ "$one" = "$two" ]] ; then
         retval=1
    fi
    return $retval
}

#sample usage
stricmp "ASCII" "ascii"
if [ $? -eq 1 ] ; then
   echo "equal"
else
   echo "not equal"
fi

Another ksh function :
Code:
#/bin/ksh

icmp()
{
   typeset -u one="$1"
   typeset -u two="$2"
   [ "$one" = "$two" ]
}

#sample usage

if icmp "ASCII" "Ascii"
then
   echo "equal"
else
   echo "not equal"
fi
