[英]Recursively count filtered files in subfolders and group results
I want to count all files with a particular prefix in a directory and then display the results based on each sub directory. 我想计算目录中具有特定前缀的所有文件,然后根据每个子目录显示结果。
The directory tree is as follows 目录树如下
Test
January
sms20180101_110.unl
rec20180101_110.unl
data20180101_110.unl
February
sms20180201_110.unl
rec20180201_110.unl
data20180201_110.unl
March
sms20180301_110.unl
rec20180301_110.unl
data20180301_110.unl
So, I need to count for example the total data files in each subdirectory and display results as follows 因此,我需要计算例如每个子目录中的总数据文件并显示结果,如下所示
January 1
February 5
March 10
I wrote the following command in Powershell 我在Powershell中编写了以下命令
Get-ChildItem -Path D:\Test -Filter *data* -Force -Recurse | Measure-Object | %{$_.Count}
So, the problem is it is giving me the total files in the root directory 所以,问题是它给了我根目录下的全部文件
A similar question was asked here Recursively count files in subfolders but I have not been able to customize the solutions provided here to my need 在这里提出了类似的问题,以递归方式计算子文件夹中的文件,但是我无法根据我的需要自定义此处提供的解决方案
Based on your scenario, you can use Group-Object
like this - 根据您的情况,您可以像这样使用
Group-Object
Get-ChildItem -Path D:\Test -Filter *data* -Force -Recurse | Group-Object -Property Directory | Select-Object Name, Count
This will list all the name of the folders and sub-folders along with the count of files having data in it's name. 这将列出文件夹和子文件夹的所有名称,以及名称中包含数据的文件数。
