i want to write a shell script that can be run as

./deployPortal.sh -version 5.1.2 -portlet -exportall


how can i do that?
version param is required. bu the others are optional.

in first step i only want to read 5.1.2, is portlet selected ? and is exportall selected ??

can you help me??

Maybe use "getopts", "$*" or "$@", evaluate them with case or if...

Look for "positional parameters" in http://tldp.org/LDP/abs/html/othertypesv.html

or

Little example for you:

# Check for passed in arguments
for i in $*
do
case "${i}" in
-h*) help_output ;;
-s1) valid_integer ${2} && integer DEF_SCREEN1_LOOP=${2} ;;
-s2) valid_integer ${2} && integer DEF_SCREEN2_LOOP=${2} ;;
-i) [[ -n ${2} ]] && DIRECTORY_USER_DEFAULT=${2} ;;
-d) [[ -n ${2} ]] && DIRECTORY_SID_DEFAULT=${2} ;;
-o) [[ -n ${2} ]] && OPWVDB_SID_DEFAULT=${2} ;;
-t) if valid_integer ${2}
then
((${2} > DEF_INTGAP)) && integer DEF_INTGAP=${2}
fi ;;
-c) if valid_integer ${2}
then
if ((${2} <= DEF_DBMIN_LOOP && ${2} != 0));then
DEF_DBINT_LOOP=${DEF_DBMIN_LOOP}
elif ((${2} > DEF_DBMIN_LOOP));then
DEF_DBINT_LOOP=${2}
fi
fi ;;
-u) DEF_COREUSER=${2} ;;
-p) valid_integer ${2} && integer DEF_CORETTY=${2} ;;
-nocore) DEF_CORECHECK=${NO} ;;
*) ;;
esac
shift
done
