fix the wrong flags expression in getopt

[stmoon]

I found that the wrong flags expressions when using getopt function. I update the expression,

":b:d:u:p:qsr:f:i:loat" => "b:d:ui:p:qsr:loat"

Good to go?

There's a merge conflict, could you resolve it @stmoon ? Also, @Jaeyoung-Lim is the last change ok for merge?
