我正在尝试对多列进行排序。结果并不如预期。

这是我的数据（people.txt）：

Simon Strange 62
Pete Brown 37
Mark Brown 46
Stefan Heinz 52
Tony Bedford 50
John Strange 51
Fred Bloggs 22
James Bedford 21
Emily Bedford 18
Ana Villamor 44
Alice Villamor 50
Francis Chepstow 56

以下工作正常：

bash-3.2$ sort -k2 -k3 <people.txt

这对我来说绝对奇怪。我在-n应该是数字排序的手册页中读到了。为什么id要放在数字之间？它是如何，10大于9，但比小6，而同时11大于它们呢？

的-g，因为我想，似乎工作（和我认为是自然的），但是这个-n选项完全脱离了我。这是关于什么的？我认为它可能与语言环境有关，但是一旦我将分隔符指定为 is ,，我认为这无法解释它。
