linux– 无法解释sort(1)行为

概述当我看到ls以奇怪顺序列出的下列文件时,我一直很困惑：Star Wars Episode II - Attack of the Clones (2002) BDRip.mkv Star Wars Episode III - Revenge of the Sith (2005) BDRip.mkv Star Wars Episode I - The Phant

当我看到ls以奇怪顺序列出的下列文件时,我一直很困惑：

Star Wars Episode II - Attack of the Clones (2002) BDRip.mkvStar Wars Episode III - Revenge of the Sith (2005) BDRip.mkvStar Wars Episode I - The Phantom Menace (1999) BDRip.mkvStar Wars Episode IV - A New Hope (1977) BDRip.mkvStar Wars Episode VI - Return of the Jedi (1983) BDRip.mkvStar Wars Episode V - The Empire Strikes Back (1980) BDRip.mkv

从人的角度来看,“我”应该先行,然后“行进”,等等.

所以我用以下内容创建了文件：

$cat 1Star Wars Episode II - AttackStar Wars Episode III - RevengeStar Wars Episode I - TheStar Wars Episode IV - AStar Wars Episode VI - ReturnStar Wars Episode V - The

如果我对它进行排序它会给我这个：

$sort 1Star Wars Episode II - AttackStar Wars Episode III - RevengeStar Wars Episode I - TheStar Wars Episode IV - AStar Wars Episode VI - ReturnStar Wars Episode V - The

但是,如果我删除’ – ‘并且在排序正确之后的所有内容：

$cat 1Star Wars Episode II Star Wars Episode III Star Wars Episode I Star Wars Episode IV Star Wars Episode VI Star Wars Episode V $sort 1Star Wars Episode I Star Wars Episode II Star Wars Episode III Star Wars Episode IV Star Wars Episode V Star Wars Episode VI 

所以,只要我在空格后添加任何符号,它就会开始为我排序不可预测：

$cat 1Star Wars Episode II yStar Wars Episode III xStar Wars Episode I zStar Wars Episode IV wStar Wars Episode VI vStar Wars Episode V u$sort 1Star Wars Episode III xStar Wars Episode II yStar Wars Episode IV wStar Wars Episode I zStar Wars Episode VI vStar Wars Episode V u

有关此排序行为的任何提示吗？

更新：排序：使用’en_CA.UTF-8’排序规则

根据下面的评论更新#2是因为语言环境.

ls | LANG=C sortStar Wars Episode I - The Phantom Menace (1999) BDRip.mkvStar Wars Episode II - Attack of the Clones (2002) BDRip.mkvStar Wars Episode III - Revenge of the Sith (2005) BDRip.mkvStar Wars Episode IV - A New Hope (1977) BDRip.mkvStar Wars Episode V - The Empire Strikes Back (1980) BDRip.mkvStar Wars Episode VI - Return of the Jedi (1983) BDRip.mkv

为什么然后UTF8语言环境使它与众不同？
我检查了ru_RU.UTF8(错误排序)和ru_RU.KOI8-R(正确排序)

更新#3这是关于语言环境：http://www.gnu.org/software/coreutils/faq/#Sort-does-not-sort-in-normal-order_0021最佳答案我想我找到了正确的解释：

Gnu coreutils FAQ: Sort does not sort in normal order

发现于：sort not sorting as expected (space and locale) 总结
