bash 排序没有按期望按字段进行数字排序

Question

我一直在尝试对文件名列表进行数字排序。

它们都被命名为

某物.txt~NUM~

我尝试过按以下方式排序

排序-t“〜”-k1 -k2n

但排序结果不对。如果我这样做

排序-n

然后它们按需要按数字排序，但文件句柄未排序。

这是一个测试文件

我正在运行 Sierra OSX。因此，特别是，sort -V对我来说不可用。我还知道如何使用 perl 脚本获得所需的结果。因此，问题不在于如何获得所需的结果，而在于如何使用“sort”来实现这一点。

Answer 1

你首先要排序仅有的按字段 1 排序，如果出现平局则查看字段 2：

sort -t'~' -k1,1 -k2,2n

当您使用 时-k1，您将按字段 1 排序取决于行尾。当您这样做时，没有平局，因此按字段 2 排序永远不会启动。
