我得到了一个具有以下模式的文件：

10:15:16:290 53123

10:15:16:728 9578781
10:15:16:712 62

使用我的代码，我尝试使用以下代码按数字对短行进行排序：

$result = [System.IO.File]::ReadLines($file).Trim() |
Group-Object @{Expression = { [int] $_.Substring($_.Length - 8)} } | # group by InvokeID (last 8 characters of the shortline) 
Where-Object { $_.Count -eq 2 } | # select only groups with two items in it (one long and one short line)

我的问题是数字并不总是具有相同的长度。我怎样才能使它动态？我得到了从 1 位到 8 位的数字。

使用-replace带有正则表达式的运算符来删除除尾随连续数字之外的所有内容：

... |Group-Object { ($_ -replace '^.*?(\d+)$', '$1') -as [int] }
