I have a folder at C:\Folder that has files input.xml, output.xml and licensegenerator.exe. Licensegenerator.exe takes variables that we put into input.xml and creates a temporary license for one of our programs using the output.xml file. We typically do this via command line by navigating to the C:\Folder directory, then running the command:
LicenseGenerator.exe "C:\Folder\input.xml" "C:\Folder\output.xml"
I'm attempting to write a script to do the exact same thing in PowerShell, but I'm struggling... Here's what I have:
$inputtest = "C:\Folder\Input.xml"
$outputtest = "C:\Folder\Output.xml"
$licensegen = "C:\Folder\LicenseGenerator.exe"
Invoke-Command $licensegen "$inputtest" "$outputtest"
When I run this, I get the error:
Invoke-Command : A positional parameter cannot be found that accepts argument
'C:\Folder\Output.xml'.

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I have also tried running with Invoke-Expression but get the exact same error (except it says "Invoke-Expression" at the beginning). Anybody have any idea what I'm doing wrong here?
You're looking for the call operator (&):
& $licensegen "$inputtest" "$outputtest"
Invoke-Command is essentially for running scriptblocks on other hosts and/or in other user contexts.
Start-Process
is great because you can runas, redirect output, hide the child processes window and much more.
Start-Process -FilePath $licensegen -Argumentlist $inputtest,$outputtest
& "[path] command" [arguments]
Just replace Invoke-Command with &

I need to execute a command file (B.cmd) on Machine B from a Powershell script (A.ps1) on Machine A. I don't want to statically specify the path
B.cmd is supposed to execute C.ps1 which is in the same folder as B.cmd
MACHINE A: A.ps1
MACHINE B: B.cmd, C.ps1 (all in same folder)
so my command file looks like this B.cmd
#echo off
powershell.exe -file ".\C.ps1" -Iterations 10
echo
echo
pause
There's an error thrown in a A.ps1 file from which I'm calling the B.cmd file
A.ps1
Invoke-Command -ComputerName $systemName -credential $credentials -ScriptBlock {Invoke-Expression -Command: "cmd.exe /c C:\Temp\Batch\Test\B.cmd"}
A.ps1 throws error:
**The argument '.\C.ps1' to the -File parameter does not exist. Provide the path to an existing '.ps1' file as an argument to the -File parameter.**

How do I make the .\ work or is there an alternative or is it wrong to use the .\ for a remote execution ?
Please forgive my ignorance anywhere as I'm very very new to PS, Thank You !
If you're able to change the ABC.cmd you could use the following
powershell.exe -file "%~dp0\XYZ.ps1"
This will get the folder the ABC.cmd script is running from. Note that %~dp0 won't work in cmd for testing you'll need to test it from within a script.
So don't wrap a batch file around it. A waste of time and confuses the issue.
invoke-command -comp $computername -filepath C:\Temp\Batch\Test\XYZ.ps1
If you need to run something 10 times, do it in a loop inside your PS script.
I have the need to run PowerShell scripts using the command prompt (calling powershell.exe with the -c parameter). I have run these for years but have never tried it with Invoke-Command in order to do remoting and when the script I want to execute has a switch I have to pass.
This piece of code works great from PowerShell, a simple script that has the LogRun switch:
icm -cn MYCOMPUTER02 {C:\Temp\Write-to-File.ps1 -LogRun $Using:LogRun}
However, when I run it via the Command Prompt with powershell.exe fails:
powershell -c "icm -cn MYCOMPUTER02 {C:\Temp\Write-to-File.ps1 -LogRun $Using:LogRun}"
I have tried many variations of this and nothing works, I am sure I missing some syntax detail or some quotes somewhere.
Please let me know if you can help me figure this out.
This is the error I get:
icm : The value of the using variable '$using:LogRun' cannot be retrieved
because it has not been set in the local session.

I'm trying to run a powershell script to search for a network drive for a certain file. In my testing, I've found that my script works perfectly fine, however the network drive I need to search require my Domain Admin logon.
I have
Start-Process powershell.exe -Credential "domain\adminusername" -NoNewWindow -ArgumentList "Start-Process powershell.exe -Verb runAs"
as the very first line of my script, but whenever I run the script I get this error:
Start-Process : This command cannot be run due to the error: The directory
name is invalid.

What directory name is it talking about? If I move the script to the actual network drive, I still get the same error. How do you run a script as a different user?
You could use the net use command to gain access or the new-psdrive command instead. Another option would be to start-process a cmd prompt and use runas within it. Also, you may need to include the full path of powershell.exe or add it to the path variable. %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe
I tried the solution given from: Specify the size of command prompt when executing a batch file
I ran:
powershell -command "&{set-executionpolicy remotesigned; Import-Module SetConsoleFont; Get-ConsoleFontInfo | Format-Table -AutoSize}"
But I get these errors, any ideas?
Set-ExecutionPolicy : Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. At line:1 char:22 + &{set-executionpolicy <<<< remotesigned; Import-Module SetConsoleFont; Get-ConsoleFontInfo | Format-Table -AutoSize} + CategoryInfo : NotSpecified: (:) [Set-ExecutionPolicy], UnauthorizedAccessException + FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.SetExecutionPolicyCommand

I have put the file SetConsoleFont.psm1 in
C:\Users\Adrian\Documents\WindowsPowerShell\Modules\SetConsoleFont
You say "You're not allowed to set the execution policy" well maybe I'm not, but it's my machine so why shouldn't I? I don't want to execute these commands as Administrator, just as a user, me (Adrian)
Another comment was to try set-executionpolicy bypass process
so I tried:
powershell -command "&{set-executionpolicy bypass process; set-executionpolicy remotesigned; Import-Module SetConsoleFont; Get-ConsoleFontInfo | Format-Table -AutoSize}"
But got even more red errors.
I have no idea what powershell is or how to use it, I just want to change the font from a batch file without hassle!
Try set-executionpolicy bypass process instead.
Also make sure you have put the module in a module path folder such as:
[yourprofile]\Documents\WindowsPowershell\Modules
I managed to get it working but only in a PowerShell console, and I had to run it as Administrator. However this is not practical for me for the following reasons:
I wish to change the font of new window seamlessly from a batch file, which will be run by users of the software. They may not have Administrator access and so cannot execute "set-executionpolicy remotesigned" which I needed to do to get it working.
Also this has to be done in a DOS batch file, so opening up a powershell window is not an option. It only works in a PowerShell window and not with the DOS "powershell -command" option.
So a partial answer.
If you want to change Execution Policy, it should be done in an elevated prompt.
And loading the module can be done by giving absolute path. Example is below.
Import-Module c:\users\testuser\desktop\SetConsoleFont.psm1 -Verbose
and we can bypass execution policy like below.
powershell.exe -executionpolicy bypass -command "${<your code>}"
Edit: The imported module will be available only in the scope of the script block.
here it is with in {}. So whatever cmdlets and functions in side the module should be executed in sided the scriptblock.

I'm currently writing a powershell script that asks for a single set of admin credentials, and uses those to run relevant applications, pulled from a network-hosted CSV. When I try to run
Start-Process $tools[$userInput-1].path.toString() -credential $credential
(where $tools is returning "C:\Program Files\Microsoft\Exchange Server\V14\Bin\Exchange Management Console.msc") I get the error below
Start-Process : This command cannot be executed because the input "C:\Program Files\Microsoft\Exchange Server\V14\Bin\Exchange Management Console.msc" is an Invalid Application. Give a valid application and Run your command again.
At line:1 char:14
+ Start-Process <<<< "C:\Program Files\Microsoft\Exchange Server\V14\Bin\Exchange Management Console.msc" -credential
Get-Credential
+ CategoryInfo : InvalidOperation: (:) [Start-Process], InvalidOperationException
+ FullyQualifiedErrorId : InvalidOperationException,Microsoft.PowerShell.Commands.StartProcessCommand
If I need to, I'll just write a .bat file and run that, but I'd rather avoid that whenever possible.
And the reason I'm not using Invoke-Item is because it can't take -Credential, even if the man file says otherwise.
.msc is a saved console file, the host of which is mmc, so to start this from powershell you could use syntax similar to the following:
$mmcPath = "C:\Windows\System32\mmc.exe"
$mscPath = "C:\Program Files\Microsoft\Exchange Server\V14\Bin\Exchange Management Console.msc"
Start-Process -FilePath $mmcPath -ArgumentList $mscPath
