here is what i used for a script i wrote for command line option checking. its right from my script so you will have to edit it your self for your needs. also i got the outline of this from tldp.org's advanced bash shell scripting guide

Code:
NO_ARGS=0
E_OPTERROR=65

if [ $# -eq "$NO_ARGS" ] # should check for no arguments
then
	echo "Usage: `basename $0` -s<OPTIONS> <HOSTNAME> "
	echo "You must specify interactive, or non interactive mode for now"
	echo "Try './serverstatus -h' for more information."
	exit $E_OPTERROR
fi

while getopts ":sinvh" Option
do
	case $Option in

		s )
			hostname=`echo $@`
			hostname2=`echo $hostname|awk '{print $2}'`
			echo $hostname2
			a=`nmap $hostname2`

		;;

		i )
			interactivemode_func
		;;

		n )
			non_interactivemode_func
		;;

		v )
			version_func
		;;

		h )
			help_func
		;;

		* )
			echo "Unimplemented option chosen"
		;;
	esac
done

shift $(($OPTIND - 1))

i put that in a function called main() and called the function with

Code:
main "$@"


credit to perderabo for showing me that last part, i dont think i would ever have figured that out without his help.

ppmtosixel

ppmtosixel(1)						      General Commands Manual						     ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.	The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
	      pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order	of  magni-
	      tude larger than a compressed file and prints much slower.

       -margin
	      If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
	      fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater	than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
