i) action="installworld"; flag_count=$((flag_count+1));;
But when tested it just put 1 into flag_count. it is not adding one to
the value all ready in flag_count.
Stilling missing the point here
I want to perform math here. if more than one flag is coded them I want
the count to increase by 1 for each flag on the command, not change the
contents of the count to 1.
Again take note this is .sh shell type.
