How to execute powershell commands (not from ps1 file) from cmd.exe

Question

I am trying to execute powershell if-else from cmd. For example to check the number of files, that has "temp" in its name in D: drive,I used,

if(($i=ls D:\* | findstr /sinc:Temp).count -ne 0 ) {Write-Host $i}

This works fine from PS windows

But if want to do the same from cmd, How do i do it? I tried

powershell -noexit if(($i=ls D:\* | findstr /sinc:Temp).count -ne 0 ) {Write-Host $i}

which did not work unfortunately.

Answer 1

Just put the command in double quotes:

powershell "if(($i=ls D:\* | findstr /sinc:Temp).count -ne 0 ) {Write-Host $i}"

I also think you don't need the -NoExit switch here. This switch prevents powershell from exiting after running the command. If you want to return back to cmd, remove this switch.

Answer 2

I know this doesn't answer how to run the command(others have covered it already), but why would you want to combine cmd and powershell, when both can do the job alone?

Ex powershell:

#Get all files on D: drive with temp in FILEname(doesn't check if a foldername was temp)
Get-ChildItem D:\ -Recurse -Filter *temp* | where { !$_.PSIsContainer } | foreach { $_.fullname }

#Check if fullpath includes "temp" (if folder in path includes temp, all files beneath are shown)
Get-ChildItem D:\ -Recurse | where { !$_.PSIsContainer -and $_.FullName -like "*temp*" } | foreach { $_.fullname }

Ex cmd:

#Get all files with "temp" in filename
dir d:\*temp* /s /a:-d /b
