How to check if powershell is installed?

[Adrianvdh]

Hello everyone...

I am asking a rather simple question but I can't get my code to work with it.
How do I check if powershell is installed?

I have tried...

Code: Select all

if exist "powershell.exe" (echo Exist ) else (echo Sorry mate )
pause

But I could probably get that to work using the correct directories.

But I don't want to have messy code with the following directories saying v1.0, v2.0 etc and x86, x64 version directories.

How can I solve this with a few lines of code?

BTW I need this, because if powershell is not installed my script would shout out an error and rather run on wget to the my job..

Thanks. Hope you can help

Powershell should always be placed in the PATH environment. For that reason the ~$path modifier of FOR variables should be suitable.

Code: Select all

for %%i in (powershell.exe) do if "%%~$path:i"=="" (echo Sorry mate) else echo Exists
