How to use -ArgumentList with Invoke-Command to pass flags to a script?
# File: ./setup.ps1
param(
[Parameter(Mandatory=$false)]
[alias("force")]
[switch]$opt_force
)
if ($opt_force) {
write-host "FORCING something!"
}
write-host "Done"
Powershell Command Line:
PS> Invoke-Command -Computer pv3039 -FilePath ./setup.ps1 -ArgumentList "-force"
Error Message:
positional parameter cannot be found that accepts argument '-force'.
+ CategoryInfo : InvalidArgument: (:) [], ParameterBindingException

If you want to call a remote script, you can use Start-Process instead of Invoke-Command. Maybe you can try something like this.
Start-Process PowerShell -ArgumentList "YOUR_SCRIPT_PATH\setup.ps1 -Force" -NoNewWindow -Wait
This way it can accept parameters from the called script.
I'm running SSISDeploy command (documentation is here) in my CMD:
SSISDeploy.exe -s:"download\Integration Services.ispac" -d:catalog;/SSISDB/TEST/DEVOPS;"TEST03,1234" -at:win
all working good, and now I need to run it thought powershell script (against windows server 2019 slave), so I tried this syntax:
$SSISDeploy = Start-Process -FilePath SSISDeploy.exe -ArgumentList '/source:"download\Integration Services.ispac"',"/destination:catalog;${Target};"${Env}"" -at:win -wait -PassThru -Credential $cred -RedirectStandardOutput ssisstdout.txt -RedirectStandardError ssisstderr.txt
but it fails with exception:
Start-Process : A positional parameter cannot be found that accepts argument 'TEST03,1234'.
+ ... SISDeploy = Start-Process -FilePath SSISDeploy.exe -ArgumentList '/so ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Start-Process], ParameterBindingException
+ FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.StartProcessCommand
Can you suggest what's wrong with the syntax?
$StartProcessProps = #{
FilePath = 'SSISDeploy.exe'
ArgumentList = '-s:"download\Integration Services.ispac" -d:catalog;{0};{1} -at:win' -f $Target, $Env
Wait = $true
PassThru = $true
Credential = $cred
RedirectStandardOutput = 'ssisstdout.txt'
RedirectStandardError = 'ssisstderr.txt'
}
$SSISDeploy = Start-Process #StartProcessProp
I am trying to run a powershell script which will have run only after passing a parameter value as an argument. The script has few commands that run only with elevated access so trying to use -runAs verb like below:
PowerShell.exe -Command "& {Start-Process PowerShell.exe -ArgumentList '-ExecutionPolicy Bypass -File ""%~reset-password-services_logs.ps1 'h5rU!J5L_sitL0Y'""' -Verb RunAs}"
I need to pass the argument 'h5rU!J5L_sitL0Y' with the script in order to successfully execute the process. Error i get is below:
Start-Process : A positional parameter cannot be found that accepts argument
'h5rU!J5L_sitL0Y'.

I tried different ways to escape the space in "Program Files" but this is not working. I receive the following error in Jenkins after this part is executed:

If I change the Invoke-Command to the following, the Program Files directory seems to be resolved correctly, but then the variable $filename is not resolved anymore.
Invoke-Command -Session $session -ScriptBlock {cmd /c \'"C:\\Program Files\\7-Zip\\7z.exe" x C:\\Data\\Install\\$filename -oC:\\data\\install\\test -aoa >NUL'}

Hopefully you can assist me in this case! The rest of the commands is working fine.
Thanks!
The 7z.exe path in your first command has an extraneous trailing \, which causes problems:
cmd /c "C:\\Program Files\\7-Zip\\7z.exe\\" # <- trailing \\ shouldn't be there
In your 2nd command, you're using single quotes around the command passed to cmd /c ('...'), but the contents of '...' strings in PowerShell are treated as literals, which explains why $fileName was not expanded (interpolated);
only double-quoted ("...") strings and, within limits, unquoted command arguments are expanded in PowerShell; e.g., compare the output from Write-Output '$HOME' to the output from Write-Output "$HOME" / Write-Output $HOME.
As iRon mentions, there's no need to involve cmd at all - PowerShell is perfectly capable of executing command-line programs directly, so this should work:
Invoke-Command -Session $session -ScriptBlock { & "C:\\Program Files\\7-Zip\\7z.exe" x C:\\Data\\Install\\$using:filename -oC:\\data\\install\\test -aoa >$null }
Due to invoking 7z.exe directly, now there's no outer quoting needed anymore, and $fileName should be expanded.
Note, however, that $fileName was replaced with $using:fileName, which is necessary in order for the target session to know about the local $fileName variable - see Get-Help about_Remote_Variables.
Since the 7z.exe file path is quoted (of necessity, due to containing spaces), you must use &, the call operator, to invoke it.
Since the > redirection is now performed by PowerShell itself, the cmd-style >NUL output suppression was replaced with its PowerShell analog, >$null.
I wonder if it necessarily at all to invoke a CMD shell for this.
I guess it would be simpler to directly invoke the 7z.exe with its parameters.
Nevertheless, you can build you own script block like this:
[ScriptBlock]::Create('cmd /c "C:\\Program Files\\7-Zip\\7z.exe" x C:\\Data\\Install\\' + $filename + ' -oC:\\data\\install\\test -aoa >NUL')
I have the below PowerShell code:
$HOME_DIR=[Environment]::GetEnvironmentVariable("HOME")
$WORKING_PATH="C:\tests\automation"
$TOOLS_PATH="$WORKING_PATH\Tools"
Start-Process -FilePath "$HOME_DIR\perl\perl.bat" "$TOOLS_PATH\my_perl_script.pl" -ArgumentList 'arg1' 'arg2' -NoNewWindow
I'm getting error:
Start-Process : A positional parameter cannot be found that accepts argument 'C:\tests\automation\Tools\my_perl_script.pl'.
At C:\RunUIAutomaionTests.ps1:46 char:14

+ CategoryInfo : InvalidArgument: (:) [Start-Process], ParameterBindingException
+ FullyQualifiedErrorId :<br> PositionalParameterNotFound,Microsoft.PowerShell.Commands.StartProcessCommand
What I'm missing?How should I execute my_perl_script.pl using perl.bat with the arguments 'arg1' and 'arg2'?
Why so complicated?
You can call perl doirectly like that:
...
$TOOLS_PATH="$WORKING_PATH\Tools"
...
perl $TOOLS_PATH\my_perl_script.pl arg1 arg2
Just make sure perl executable is in Windows path
