I am updating TortoiseGit repository using the following code (which works) in command line file (MyTestRepo.cmd):
cd c:\MyTortoiseGitRepo
git.exe pull --progress -v --no-rebase "origin"
In PowerShell I am calling this file using the following code:
$TestPull = Start-Job { Invoke-Item C:\MyTests\MyTestRepo.cmd }
Wait-Job $TestPull
Receive-Job $TestPull
The above code does work but it is not waiting long enough for the CMD file to finish running and exit cmd.exe to exit before moving on to the next line of code.
What better way to you have to wait for the cmd.exe process to finish before moving on?
Invoke-Item doesn't support waiting. You can use the call operator &. Ex:
$TestPull = Start-Job { & "C:\MyTests\MyTestRepo.cmd" }
Or Start-Process -Wait:
$TestPull = Start-Job { Start-Process -FilePath "C:\MyTests\MyTestRepo.cmd" -Wait }
Start-Process will show the cmd-window when the script is excecuted by a user. This can be suppressed by adding -NoNewWindow`.

$argList = "-file `"C:\Users\bdl\Desktop\jhansi\PowerShell_Scripts\dialog.ps1`""
Start powershell -argumentlist $argList -NoNewWindow
I am trying to open another powershell terminal from the current script to execute the current script output. Another powershell terminal is opening but it is blinking continuously. The above two lines of code i have written but it is blinking. please tell me where is the mistake in the above two lines.
You can try something like this:
$ArgList = "C:\Users\bdl\Desktop\jhansi\PowerShell_Scripts\dialog.ps1"
Start-Process -FilePath PowerShell -ArgumentList $ArgList -NoNewWindow -Wait
You can also check if the script called in PowerShell returns successfully or not by adding an exit code into it (Exit 0 means it succeed and Exit 1 if it fails) with:
$Exe = (Start-Process -FilePath PowerShell -ArgumentList $ArgList -NoNewWindow -Wait -PassThru).ExitCode
If ($Exe -ne 0)
{
Write-Host "An error has occured while running the script."
}
As the exit code other than 0 means the script didn't finish properly.
I have an update script for running the Dell Command Update tool. In short dcu-cli.exe. The thing now is than when i run the same script code on the computer local then everything runs OK but when i run the exact same code in a script with invoke-command(and yes i have full admin rights) than the exitcode is 2 meaning An unknown application error has occurred instead of 0 (everything OK)
It is a very large script so i created a new one to debug this. This is the shorted code:
Invoke-Command -ComputerName "MyComputer" -ScriptBlock {
$ExitCode = 0
#Declare path and arguments
$DcuCliPath = 'C:\Program Files (x86)\Dell\CommandUpdate\dcu-cli.exe'
$DellCommand = "/applyUpdates -autoSuspendBitLocker=enable -outputLog=C:\Dell_Update.log"
#Verify Dell Command | Update exists
If (Test-Path -Path $DcuCliPath) {
$objWMI = Get-WmiObject Win32_ComputerSystem
Write-Host ("Dell Model [{0}]" -f $objWMI.Model.Trim())
$serviceName = "DellClientManagementService"
Write-Host ("Service [{0}] is currently [{1}]" -f $serviceName, (Get-Service $serviceName).Status)
If ((Get-Service $serviceName).Status -eq 'Stopped') {
Start-Service $serviceName
Write-Host "Service [$serviceName] started"
}
#Update the system with the latest drivers
Write-Host "Starting Dell Command | Update tool with arguments [$DellCommand] dcu-cli found at [$DcuCliPath]"
$ExitCode = (Start-Process -FilePath ($DcuCliPath) -ArgumentList ($DellCommand) -PassThru -Wait).ExitCode
Write-Host ("Dell Command | Update tool finished with ExitCode: [$ExitCode] current Win32 ExitCode: [$LastExitCode] Check log for more information: C:\Dell_Update.log")
}
}
When i remove the Invoke-Command -ComputerName "MyComputer" -ScriptBlock { and then copy + run the script local on the PC then the exitcode = 0
What i also noticed than when i run the command via 'Invoke-Command' then there is also no log file created as i passed along in the arguments... So my best guess is something is going wrong with local an remote paths?
So what am i missing? I'm guessing it is something simple but i spend several hours to get this running without any luck...
Try running it this way. You should be able to see any output or error messages. I typically add to the path first rather than using & or start-process.
invoke-command mycomputer {
$env:path += ';C:\Program Files (x86)\Dell\CommandUpdate';
dcu-cli /applyUpdates -autoSuspendBitLocker=enable -outputLog=C:\Dell_Update.log }
Using start-process inside invoke-command seems pretty challenging. I can't even see the output of findstr unless I save it to a file. And if I didn't wait the output would be truncated. By default start-process runs in the background and in another window. There's a -nonewwindow option too but it doesn't help with invoke-command.
invoke-command localhost { # elevated
start-process 'findstr' '/i word c:\users\joe\file1' -wait -RedirectStandardOutput c:\users\joe\out }
#js2010, thanks for your additional help. Unfortunately this didn't helped either.
So i did some more debugging and it turns out it was a bug in the dcu-cli version running on my test machine, DOH...!!
On the test machine version 3.1.1 was running and on another machine version 4.0 was running and that worked fine via remote Powershell. So i looked for the release notes, which i found here: https://www.dell.com/support/kbdoc/000177325/dell-command-update
And as you can see in version 3.1.3 there was this fix:
A problem was solved where dcu-cli.exe was not executed in an external interactive session of PowerShell.
I'm trying to run below code in an automated scheduled task.
Whether I run this task manually or automated it is not working. When the option 'Run only when user is logged in' is set I at least see a PowerShell window opening, and I do see the jobs getting started. However, when the PS window closes the jobs are not visible (not completed, failed, nothing).
The logging shows the script runs till the import-csv command. I have put the CSV in the C: map, and I run the automated task as the logged in user and on highest privilege.
Why doesn't it get past import-csv? When I run this script in i.e Powershell ISE it works like a charm.
Running program
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
Arguments:
–NoProfile -ExecutionPolicy Unrestricted -File "C:\Users\usr\Desktop\Scripts\script.ps1"
Start-in:
C:\Users\usr\Desktop\Scripts
Write-Host "Starting script"
$maxItems = 8
$iplist = import-csv "C:\Create.csv.txt"
Write-Host "Opened $($iplist[0])"
For ($i=0; $i -le $maxItems; $i++) {
Write-Host $iplist[$i].DisplayName
Start-Job -ScriptBlock {
Param($displayName)
try{
Start-Transcript
Write-Host "Found and started a job for $($displayName)"
Stop-Transcript
}
Catch{
Write-Host "Something went wrong "
Stop-Transcript
}
} -ArgumentList $iplist[$i].DisplayName
}
UPDATE:
The PS window closed before it got to do anything. The answer in this page send me in the right direction. The full fix I used to get this working:
Task Scheduling and Powershell's Start-Job
First, to prevent the powershell window from closing, run add the following line to the bottom of the script:
Read-Host 'Press Any Key to exit'
Second, if you run into issues with params, try explicitly naming the param with a flag:
$iplist = Import-csv -LiteralPath "C:\Create.csv.txt"
Third, make sure that you explicitly declare the delimiter being used if different than a comma.
I have a process that would traditionally be run like so (in the command line):
filepath.exe #"respfile.resp"
where respfile.resp is a response file that has command line arguments for the executable.
Running the command like that works as desired in the command prompt.
However I am trying to use a powershell script to run multiple programs. Here is what I have:
if (Test-Path $respPath){
$executionResposne = Start-Process -NoNewWindow -Wait -PassThru -FilePath $bimlcExePath -ArgumentList $respPath
if ($executionResposne.ExitCode -eq 1){
Write-Output "Unable to successfully run the process. Exiting program."
return
}
}
and I am getting the following error message:
Error:: filepath\to\resp\file Data at the root level is invalid.
How can I make this work?
You need to embed the quotes for the interpreter:
-ArgumentList "#`"$respPath`""
I have a Java program which I would like to launch as a background process from a PowerShell script, similar to the way a daemon runs on Linux. The PowerShell script needs to do a couple of things:
Run the program as a separate and detached process in the background, meaning the parent window can be closed and the process keeps running.
Redirect the program's standard output and standard error to files.
Save the PID of the background process to a file so it can be terminated later by another script.
I have a shell script on Linux which starts the program like so:
$ java -jar MyProgram.jar >console.out 2>console.err &
I'm hoping to replicate the same behavior on Windows using a PowerShell script. I have tried using Start-Process with various combinations of options, as well as creating System.Diagnostics.ProcessStartInfo and System.Diagnostics.Process objects, but so far I am not having any luck. PowerShell starts the program as a background process, but the program abruptly terminates when the DOS window which started the PowerShell session is closed. I would like it to start in the background and be independent of the command window which started it.
The output redirection has also been troublesome, as it seems that the output and error streams can only be redirected in the process is being run in the same window (e.g., using -NoNewWindow).
Is this sort of thing possible in PowerShell?
Use jobs for this:
Start-Job -ScriptBlock {
& java -jar MyProgram.jar >console.out 2>console.err
}
Another option would be Start-Process:
Start-Process java -ArgumentList '-jar', 'MyProgram.jar' `
-RedirectStandardOutput '.\console.out' -RedirectStandardError '.\console.err'
Consider using the task scheduler for this. Define a task and set it without any triggers. That will allow you to simply "Run" (manually trigger) the task.
You can set up and/or trigger scheduled tasks using the ScheduledTasks powershell module, or you can use the GUI.
This is an old post but since I have it working fine thought it might help to share. Its the call to 'java' instead of 'javaw' that is likely your issue. Ran it out myself using my JEdit java program through powershell to launch it.
#Requires -Version 3.0
$MyDriveRoot = (Get-Location).Drive.Root
$JEditDir = $($mydriveroot + "jEdit") ;# Should be C:\jEdit or wherever you want. JEdit is a sub-directory.
$jEdit = $($JEditDir + "\jedit.jar" )
$jEditSettings = $($JEditDir + "\settings")
$JEditLogs = $($JEditDir + "\logs")
Start-Process -FilePath javaw -ArgumentList ( '-jar',"$jEdit", '-settings="$JEditSettings"' ) -RedirectStandardOutput "$JEditLogs\console.out" -RedirectStandardError "$JEditLogs\console.err"
Which you can turn into a little function and then an alias to make it easy to launch in Powershell.
If ( ( Test-Path $jedit) ) {
Function Start-JEdit() {
Start-Process -FilePath javaw -ArgumentList ( '-jar',"$jEdit", '-settings="$($mydriveroot + "jEdit\settings")"' ) -RedirectStandardOutput "$JEditLogs\console.out" -RedirectStandardError "$JEditLogs\console.err"
}
New-Alias -Name jedit -Force Start-JEdit -Description "Start JEdit programmers text editor"
}
Try this with PowerShell:
Start-Process cmd -Args /c,"java -jar MyProgram.jar" `
-WindowStyle Hidden -RSI console.out -RSE console.err
OR
Start-Process cmd -Args /c,"java -jar MyProgram.jar >console.out 2>console.err" `
-WindowStyle Hidden
This will start a detached cmd window that is hidden, and will redirect the std streams accordingly.
Old question, but since I had the same goal, I used answer from #use to acheive it.
So here is my code :)
$NAME_TASK = "myTask"
$NAME_TASKPATH = "\myPath\"
if ($args[0] -eq "-task") {
# Code to be run "detached" here...
Unregister-ScheduledTask -TaskName $NAME_TASK -TaskPath $NAME_TASKPATH -Confirm:$False
Exit
}
$Task = (Get-ScheduledTask -TaskName $NAME_TASK -TaskPath $NAME_TASKPATH -ErrorAction 'SilentlyContinue')
if ($Task) {
Write-Host "ERR: Task already in progress"
Exit 1
}
$A = New-ScheduledTaskAction -Execute "PowerShell.exe" -Argument "-ExecutionPolicy bypass -NoProfile -Command ""$PSCommandPath -task $args"""
Register-ScheduledTask -TaskName $NAME_TASK -TaskPath $NAME_TASKPATH -Action $A | Start-ScheduledTask
The solution is to combine Start-Process with nohup:
