last_patch89 from vodz:
Manuel, I rewrite bb_getopt_ulflags() function for more universal usage. My version support now: - options with arguments (optional arg as GNU extension also) - complementaly and/or incomplementaly and/or incongruously and/or list options - long_opt (all applets may have long option, add supporting is trivial) This realisation full compatibile from your version. Code size grow 480 bytes, but only coreutils/* over compensate this size after using new function. Last patch reduced over 800 bytes and not full applied to all. "mkdir" and "mv" applets have long_opt now for demonstrate trivial addition support long_opt with usage new bb_getopt_ulflags(). Complementaly and/or incomplementaly and/or incongruously and/or list options logic is not trivial, but new "cut" and "grep" applets using this logic for examples with full demostrating. New "grep" applet reduced over 300 bytes. Mark, Also. I removed bug from "grep" applet. $ echo a b | busybox grep -e a b a b a b But right is printing one only. --w vodz
