关于find命令查找的排序规则探索以及排序方法

1、linux中find命令的排序规则

2、linux shell编程中文件查找并排序的方法

1. 目的

在研读 doxygen 源码时，在不同电脑、不同操作系统上使用了 find 命令，发现对于相同的 doxygen 源码目录、相同的 find 命令参数，得到了不同顺序的结果。尝试了解下 find 命令的参数，希望得到统一一致的结果，对不同结果的原因稍作分析。

简单的结论: find . -maxdepth 1 -type d 这样的命令后， 接入管道和 sort -V 得到自然排序结果:

find . -maxdepth 1 -type d | sort -V 2. 准备：克隆 doxygen 源码

git clone https://gitee.com/mirrors/doxygen
git checkout 79a9efb

* 79a9efb 2023-05-18 | Merge pull request #10052 from albert-github/feature/bug_regr_ca65fd0bbb717a3f65e64bfcebe36a5debba66fa (grafted, HEAD -> master, origin/master, origin/HEAD) [Dimitri van Heesch]

我们希望用 find 命令，打印出 doxygen 目录下的第一级子目录。

关于find命令查找的排序规则探索以及排序方法 1、linux中find命令的排序规则

find命令的搜寻条件直接关系到输出结果，默认应该是按从左到右的的顺序判断，如果有逻辑运算（-not、-and、-or）还得再判断条件组合。
find查询的结果是找到一个匹配的项就立即输出结果，一边查找一边输出，查找到的内容不是一次性输出的，所以可能没有统一排序。
但是具体排序规则需要分析find命令的底层实现了。

2、linux shell编程中文件查找并排序的方法

方法一：

find dir -name "*.txt" | sort

方法二：

ls $(find dir -name "*.txt")
