Run powershell script from commandline, pass in directory as paramater and use a Get-Date to format-CodePudding

I want to run a script from commandline, which takes in a file directory as one of the parameters. The files are log files, which are postfixed by a date in following format: yyymmdd (Get-Date -Format filedate). I want to get the latest log file to be passed into the pwoershell script. e.g logfile-20210928.json

> e.g powershell.exe -NonInteractive -NoProfile -ExecutionPolicy
> RemoteSigned -File "D:\someapp\checkfile.ps1" -Path
> 'D:\logs\logfile-$(Get-Date -Format filedate).json'

I get the following error as powershell thinks -Format is a parameter.

A positional parameter cannot be found that accepts argument '-Format'.

CodePudding user response：

You are posting your 'Get-Date' part in single quotes, the variable is therefor plain text. try:

"D:\logs\logfile-$(Get-Date -Format filedate).json"

Since you are using cmd to open the file you can not use powershell's Get-Date function in the commandline, you can try:

D:\logs\logfile-%date:~-4,4%%date:~-7,2%%date:~-10,2%.json

So the .bat file will be:

powershell.exe -NonInteractive -NoProfile -ExecutionPolicy RemoteSigned -File "D:\someapp\checkfile.ps1" -Path "D:\logs\logfile-
