cmdlet作为另一个的输入

Question

我有以下PowerShell命令替换文件：

(Get-Content c:\myfile.txt) | ForEach-Object {
  $_ -replace "date is x", "date is 2015.02.29"
} | Set-Content c:\myfile.txt

我希望硬编码日期（2015.02.29）来自另一个cmdlet：

(Get-Date -format yyyy.MM.dd)

我该如何注射？

Answer 1

只需用您的命令替换您的硬编码值：

(Get-Content c:\myfile.txt) | ForEach-Object {
  $_ -replace "date is x", "date is $(Get-Date -format yyyy.MM.dd)"
} | Set-Content c:\myfile.txt
