I want to know if more that one flag has been coded on the command.
So add 1 to counter if that flag was processed. After all the flags are
processed and fall out of getopts, then check flag counter for value.
Ok I coded like this
shift; while getopts biugrs: arg; do case ${arg} in
b) action="buildworld"; $flag_count=$((flag_count+
i) action="installworld"; $flag_count=$((flag_count+1));;
u) action="freebsd-update"; $flag_count=$((flag_count+1));;
g) action="freebsd-upgrade"; $flag_count=$((flag_count+1));;
r) action="freebsd-rollback"; $flag_count=$((flag_count+1));;
s) ezjail_sourcetree=${OPTARG}; $flag_count=$((flag_count+1));;
?) exerr ${usage_update};;
esac; done; shift $(( ${OPTIND} - 1 ))
testing with 4 different flags on the command so should match here.
if $flag_count = 4; then
echo "yes 4 count"
fi
exerr "hard stop"
When it runs I get this
=1: not found
0=1: not found
0=1: not found
0=1: not found
0: not found
hard stop
What is still wrong here
