Problem in getopts

Code:
 
while getopts l:f:s:o:h: c
do
case $c in
   l)      tail -${OPTARG} /etc/passwd
           exit 2;;
   f)      head -${OPTARG} /etc/passwd
           exit 3;;
   s)      grep ${OPTARG} /etc/passwd | cut -d: -f7
           exit 4;;
   o)      OARG=$OPTARG
           exit 5;;
   h)      echo "$HELP"
           exit 6;;
       \?) echo "$USAGE"
           exit 7;;
   esac
   done
shift `expr $OPTIND - 1

Remove the : after h.

Change the while statement to the below.

Code:
 
while getopts l:f:s:o:h c

A : after option means it is expecting some argument. But for HELP option, we don't need any argument.

in getopts if we are specifying the ':' it means it is expecting some arguements,so just remove the : sign after h and that will be working fine.

Thanks
