getopts might help you. Have a look at this sample script:
Code:
m@home$cat test.sh
#! /bin/bash

#An array to hold the values passed using -c option
declare -a c_arr

#The count of -c options
c_count=0

#Go through all the optins passed
while getopts ":c:a:" o
do
        case "${o}" in
        c)
        c_arr[$c_count]=${OPTARG}
        let c_count=$c_count+1
        ;;

        a)
        a=${OPTARG}
        ;;

        *)
        echo "Wrong usage"
        exit 1
        ;;
        esac
done

if [ $c_count -eq 0 ]
then
        echo "option -c is mandatory"
        exit 1
fi

let i=$c_count-1

while [ $i -ge 0 ]
do
        echo "Got value for c option: ${c_arr[$i]}"
        let i=$i-1
done

if [ ! -z $a ]
then
        echo "Got value for a option: $a"
fi

And the output
Code:
m@home$./test.sh -c C1 -c C2 -a A
Got value for c option: C2
Got value for c option: C1
Got value for a option: A

atf-sh

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME

     atf-sh [-s shell] -- interpreter for shell-based test programs

SYNOPSIS

     atf-sh script

DESCRIPTION

     atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.

     atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL.  atf-sh executes the inter-
     preter, loads the atf-sh(3) library and then runs the script.  You must consider atf-sh to be a POSIX shell by default and thus should not
     use any non-standard extensions.

     The following options are available:

     -s shell	  Specifies the shell to use instead of the value provided by ATF_SHELL.

ENVIRONMENT

     ATF_LIBEXECDIR    Overrides the builtin directory where atf-sh is located.  Should not be overridden other than for testing purposes.
     ATF_PKGDATADIR    Overrides the builtin directory where libatf-sh.subr is located.  Should not be overridden other than for testing purposes.
     ATF_SHELL	       Path to the system shell to be used in the generated scripts.  Scripts must not rely on this variable being set to select a
		       specific interpreter.

EXAMPLES

     Scripts using atf-sh(3) should start with:

	   #! /usr/bin/env atf-sh

     Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh.  Instead, you have to hardcode
     the path to atf-sh in the script and then use the -s option afterwards as a single parameter:

	   #! /path/to/bin/atf-sh -s/bin/bash

ENVIRONMENT

     ATF_SHELL	  Path to the system shell to be used in the generated scripts.
