正则表达式匹配文件夹和所有子文件夹

Question

我需要为备份排除过滤器编写一个正则表达式来排除一个文件夹及其所有子文件夹。

我需要匹配以下内容
folder1/statistics
folder1/statistics/*
folder2/statistics
folder2/statistics/*
我想出了这个与文件夹统计信息相匹配的正则表达式，但与统计文件夹的子文件夹不匹配。
[^/]+/statistics/
如何扩展此表达式以匹配统计文件夹下的所有子文件夹？

使用以下正则表达式:

/^[^\/]+\/statistics\/?(?:[^\/]+\/?)*$/gm

Demo on regex101 .

解释:

/
  ^           # matches start of line
 [^\/]+       # matches any character other than / one or more times
 \/statistics # matches /statistics
 \/?          # optionally matches /
 (?:          # non-capturing group
   [^\/]+     # matches any character other than / one or more times
   \/?        # optionally matches /
 )*           # zero or more times
 $            # matches end of line
/
g             # global flag - matches all
m             # multi-line flag - ^ and $ matches start and end of lines
