i only seem to get the expected output IF i specify just the "-i include", without anything else.
how can this be fixed? what am i doing wrong? i want to be able to specify the "-i" or "-e" or any additional arguments, wherever i want on the command line. how is this possible?
i need this to be portable as i'll be using it across many platforms.
I need to parse parameters but the arguments could be NULL,example:
> cat getopts.sh
while getopts "a:b:" opt 2>/dev/null
do
case "${opt}" in
a) echo "A:${OPTARG}" ;;
b) echo "B:${OPTARG}" ;;
*) exit 1 ;;
esac
done
