Powershell - 如何检查具有所需创建时间的文件是否存在? [英] Powershell - How to check if file with desired creation time exists?

问题描述

我正在使用这个脚本

$date = Get-Date
Get-Childitem -name | where {$_.CreationTime -eq "$date"}

但它不起作用.我所需要的只是做一个布尔检查是否有在特定日期创建的文件.谢谢.

but it doesn't work. All I need is to do a boolean check if there is a file created in specific date. Thank you.

推荐答案

Get-Date 获取当前日期和时间.如果您将文件的创建日期与当前日期和时间进行比较，您将找不到任何文件(除非您在检索当前日期时刚刚创建了一个 ;) ).

Get-Date gets the current date and time. If you compare a file's creation date with the current date and time you won't find any files (except you just have created one while retrieving the current date ;) ).

$today = (get-date).Date
Get-ChildItem | where { $_.CreationTime.Date -eq $today }
