Repeating the same option can either have no effect (|), invert the option (^), or increase something (as in -vvvvv.)

Yes, the code has an impressive logic density, but there&amp;#x27;s a reason why modern programmers moved away from such style.</text></item></parent_chain></comment><story><title>How Old School C Programmers Process Arguments</title><url>http://www.usrsb.in/How-Old-School-C-Programmers-Process-Arguments.html</url></story>

If you make some concessions on expected behaviour, the code can be really clean and simple. But you have to know which concessions are acceptable yet yield this result, and that&amp;#x27;s super hard, at least to me.</text><parent_chain><item><author>yongjik</author><text>So it will admit any combination of -n and -x.
