当我看到由ls以奇怪的顺序列出的以下文件时，我一直对此感到困惑：
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 Phantom Menace (1999) BDRip.mkv Star Wars Episode IV - A New Hope (1977) BDRip.mkv Star Wars Episode VI - Return of the Jedi (1983) BDRip.mkv Star Wars Episode V - The Empire Strikes Back (1980) BDRip.mkv
从人的angular度来看，“我”应该先走，然后是“二”，等等。
所以我创build了以下内容的文件：
$ cat 1 Star Wars Episode II - Attack Star Wars Episode III - Revenge Star Wars Episode I - The Star Wars Episode IV - A Star Wars Episode VI - Return Star Wars Episode V - The
如果我sorting它给了我这个：
$ sort 1 Star Wars Episode II - Attack Star Wars Episode III - Revenge Star Wars Episode I - The Star Wars Episode IV - A Star Wars Episode VI - Return Star Wars Episode V - The
但是，如果我删除“ – ”，并且正确的后面的所有内容都正确：
$ cat 1 Star Wars Episode II Star Wars Episode III Star Wars Episode I Star Wars Episode IV Star Wars Episode VI Star Wars Episode V $ sort 1 Star 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，只要在空格之后添加任何符号，它就开始对我进行不可预知的sorting：
$ cat 1 Star Wars Episode II y Star Wars Episode III x Star Wars Episode I z Star Wars Episode IV w Star Wars Episode VI v Star Wars Episode V u $ sort 1 Star Wars Episode III x Star Wars Episode II y Star Wars Episode IV w Star Wars Episode I z Star Wars Episode VI v Star Wars Episode V u
这种行为的任何暗示？
更新：sorting：使用“en_CA.UTF-8”sorting规则
根据下面的评论更新＃2是因为语言环境。
ls | LANG=C sort Star Wars Episode I - The Phantom Menace (1999) BDRip.mkv 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 IV - A New Hope (1977) BDRip.mkv Star Wars Episode V - The Empire Strikes Back (1980) BDRip.mkv Star Wars Episode VI - Return of the Jedi (1983) BDRip.mkv
为什么UTF8 locale使它不同？ 我检查了ru_RU.UTF8（不正确的sorting）和ru_RU.KOI8-R（正确的sorting）
更新＃3它是关于语言环境： http : //www.gnu.org/software/coreutils/faq/#Sort-does-not-sort-in-normal-order_0021
我想我找到了适当的解释：
Gnu coreutils FAQ：排序不按正常顺序排序
找到它： 排序不按预期排序（空间和区域设置）
在使用基于语言环境的排序时，它会忽略所有非字母数字字符：
II - Attack -> "IIA" III - Revenge -> "III" I - The -> "ITh" IV - A -> "IVA" VI - Return -> "VIR" V - The -> "VTh"
LC_ALL=C ，空格字符排序在字母数字前面：
I - The -> "I -" II - Attack -> "II " III - Revenge -> "III" IV - A -> "IV " V - The -> "V -" VI - Return -> "VI "
所以这是巧合的，但它需要30多个电影才能真正失败。
