我无法完成这个脚本（选择所有 14 个组合）。你能帮帮我吗？
由 1 到 49 的 5 个数字组成的 100 个组合的列表。此脚本的目的是以等比例的方式选择这些组合中的 14 个，即包括列表中找到的所有数字，并考虑它们的出现频率。
#!/bin/bash
#Either a list of 100 combinations composed of 5 numbers ranging from 1 to 49. The purpose of this script is to choose 14 of these combinations in an equiporportional way, i.e. by including all the numbers found in the list, and by taking into account their frequency of occurrence.
numbers=() #table to store numbers
for (( i=1; i<=50; i++ )); do
numbers+=(0) #for each number (from 1 to 49), its number of occurrences is initialized to zero.
done

tmp 文件的内容（我们只使用第 5 列，不关心其他 3 列的值）。在这个例子中，100 个组合仅由 16 个不同的数字组成：
