linux - 从各种目录中随机选择一个文件并排序

Question

我有很多文本文件分布在几个目录中。我想对所有文件进行排序并创建一个文件名列表(在文本文件中)，但要按照一种特殊的定义顺序。我最初的想法是从这些目录中随机选择第一个文件 *1.txt。然后重复该过程(*2.txt、*3.txt 等)直到所有文件名都在列表中。我如何在 bash 中完成此操作？

基础知识:

从1个目录中随机选择文件:

shuf -n1 –e *

从 1 个目录中选择第一个文件:

ls | sort -n | head -1

示例:

更新:文件结构/真实文件名格式(这只是几个文件，有几百个)

初始订单:

我希望生成的输出/结果(随机打乱文件但保持数字顺序):

这会打乱源代码树中的所有文件，以稳定的排序对数字部分进行部分排序，因此其他元素保持打乱。

$ target=~/tmp/shuf
$ destination=/filepath/
$ tree $target

要将结果存储在名为 filename 的文件中，您可以重定向:

$ find $target -type f -iname "*.txt" \
   | shuf \
   | awk -F- '{printf("%s:%s\n", $0, $NF)}' \
   | sort -t : -k 2 -s \
   | cut -d : -f 1 \
   | xargs -n1 basename \
   | sed "s,^,$destination," \
   > filename
