如何在OSX中执行`sort -V`? [英] How to do `sort -V` in OSX?

问题描述

我为Linux bash shell编写了一个脚本.

I wrote a script for a Linux bash shell.

一行包含一个文件名列表并对它们进行排序.列表如下所示:

One line takes a list of filenames and sorts them. The list looks like this:

char32.png char33.png [...] char127.png

它从32变为127. 此列表的ls的默认排序是这样的

It goes from 32 to 127. The default sorting of ls of this list is like this

char100.png char101.png [...] char32.png char33.png [...] char99.png

幸运的是，有sort，它具有方便的-V开关，可以正确地对列表进行排序(如第一个示例一样).

Luckily, there is sort, which has the handy -V switch which sorts the list correctly (as in the first example).

现在，我必须将此脚本移植到OSX，并且OSX中的sort缺少-V开关.

Now, I have to port this script to OSX and sort in OSX is lacking the -V switch.

您对如何正确排序此列表有一个聪明的主意吗?

Do you have a clever idea of how to sort this list correctly?

推荐答案

它们都是以固定字符串(在您的示例中为char)开头吗?如果是这样:

Do they all start with a fixed string (char in your example)? If so:

sort -k1.5 -n

-k1.5表示对从第5个字符(即第一个数字)开始的第一个键(示例中只有一个键)进行排序. -n表示按数字排序.这也适用于Linux.

-k1.5 means to sort on the first key (there’s only one key in your example) starting from the 5th character, which will be the first digit. -n means to sort numerically. This works on Linux too.
