I supposed it should be a string comparison, like strcmp function, but it is not. coz strcmp will compare ascii code of characters in string one by one, thus above sorting should like this:<br /><br />abc-d.com<br />abca.com<br />abce.com<br /><br />one guess is that when sorting names the special characters like "." "-" will be skipped. but still got some problem when sorting following names:<br /><br />abc---d.com<br />abc--d.com<br />abc-d.com<br /><br />why can linux sorting keep this order? if it skips some special characters, above names should be compared equally and maybe sorted as a random order.<br /><br />confused, anybody has thought about that? <br /><br />-----<br />p.s.<br /><br />Haven't got updated here for quite a long time, coz I am back to program with c under linux and I believe it is a place for Java programmers.<br /><br />-----<br /><p>

Linux sorting compares unicode of strings 鈥?more about unicode is <a  class="liexternal">here</a></p><br /><br /><br /><img src ="http://www.aygfsteel.com/dedian/aggbug/97399.html" width = "1" height = "1" /><br><br><div align=right><a style="text-decoration:none;" href="http://www.aygfsteel.com/dedian/" target="_blank">Dedian</a> 2007-02-02 07:10 <a href="http://www.aygfsteel.com/dedian/archive/2007/02/02/97399.html#Feedback" target="_blank" style="text-decoration:none;">鍙戣〃璇勮</a></div>]]></description></item><item><title>How to search a file in Linux</title><link>http://www.aygfsteel.com/dedian/archive/2006/04/19/41789.html</link><dc:creator>Dedian</dc:creator><author>Dedian</author><pubDate>Tue, 18 Apr 2006 18:04:00 GMT</pubDate><guid>http://www.aygfsteel.com/dedian/archive/2006/04/19/41789.html</guid><wfw:comment>http://www.aygfsteel.com/dedian/comments/41789.html</wfw:comment><comments>http://www.aygfsteel.com/dedian/archive/2006/04/19/41789.html#Feedback</comments><slash:comments>0</slash:comments><wfw:commentRss>http://www.aygfsteel.com/dedian/comments/commentRss/41789.html</wfw:commentRss><trackback:ping>http://www.aygfsteel.com/dedian/services/trackbacks/41789.html</trackback:ping><description><![CDATA[
