I'm using chef for windows and need to run a batch file that starts up the selenium-server java service (java -jar seleniumserver.jar) as a daemon. When I try to use a windows_batch resource, it causes chef to hang during it's provisioning.
The problem is that the selenium server stays running in whatever command line you start it in, but chef won't continue provisioning the machine until the command is finished. The thing is, the command never finishes, it's not supposed to.
Here's what I've tried so far:
Executing java -jar seleniumserver.jar & (with the windows_batch resource)
Using a template to create a batch file for the command, then using windows_batch to execute file.bat
Using windows_batch to execute the batchfile with an & (file.bat &)
I'm open to any ideas, even if it's kind of hacky. Thanks in advance!
If I understand the question correctly, you can start a separate process so the main batch file ends. For example:
start java -jar seleniumserver.jar
You can control several execution parameters through the different start options.
Ending command lines with & does not do the same as *nix.
async process on windows that doesn't block chef run
batch "run" do
code 'powershell -c "start-process notepad.exe"'
end
The following is an example of using start-process to start a command with arguments.
Try running the command by itself in the command prompt to familiarize yourself with its output.
net statistics server
Now run it using powershell and start-process in the command prompt and verify the correct output shows in c:\output.txt. Please pay careful attention to the use of single or double quotes. My experience says start-process won't work with double quotes for some reason.
powershell -c start-process net -ArgumentList 'statistics workstation' -RedirectStandardOutput c:\output.txt
Now put the following in a Chef execute resource and run it. Again, be aware of the single quotes, double quotes and escaped single quotes.
execute "run" do
command 'powershell -c "start-process net -ArgumentList \'statistics workstation\' -RedirectStandardOutput c:\chef-output.txt"'
end
You should find the correct output in c:\chef-output.txt.

I have a PowerShell script ex1.ps1 which takes user inputs and ex1.ps1 has commands to open a new PowerShell to execute an exe file:
Start-Process -FilePath "$PSHOME\powershell.exe" -ArgumentList "-command C:\APPLICATION1.exe`
I want to execute ex1.ps1 on a remote host. I am trying to call ex1.ps1 using Ansible-playbook as:
# ansible-playbook script
- name: Run basic PowerShell script
win_powershell:
script: |
powershell.exe -ExecutionPolicy ByPass -File C:/Users/ex1.ps1
It is executing fine but in remote host there is no PowerShell prompt open to get the inputs.
You shouldn't be expecting manual input when deploying with a tool like Ansible. I don't know the actual program you are trying to run but the best solution here is to figure out the required parameters for the program to install/start/run without user interaction.
If you are able to provide the name of the program (and it's not something internal to your organization) a more complete answer may be able to be provided.
Unrelated to your question, unless you've over-generalized your code for this question there isn't a reason to call powershell.exe from within PowerShell just to run an executable. You can either use Start-Process or the call operator & directly with the exe path in question.
I have an answer here that goes over Start-Process and the usage of & in a bit more detail.
I'm launching a script from Oracle Data Integrator using an OS command.
Long story short: the ps1 script is invoked using powershell.exe -noninteractive script
The problem is that the caller, ODI, does not recognize the termination of the powershell script, where if i call the script in the same way from the console it correctly terminate (and I can eventually read the errorlevel i set as parameter to the exit, that is the last command I wrote in the script).
Has someone had this behaviour of powershell script? It successfully executes but the command remains pending in the task manager (the same command that ran by me in the cmd prompt exit successfully).
I found the solution, just add < NUL to the caller command:
powershell.exe script.ps1 < NUL
I'm writing a script that normally will get called by another application (VMware vCenter Server). From that application I trigger a batch file (redirect.bat) and pass a variable which is the powershell script name (TestMe.ps1).
The script is placed on a Windows Server and when I go into the command prompt of the Windows Server and call the redirect script, I see that my PowerShell script runs as expected. However when I trigger it from the app the Powershell script is not run or doesn't produce output. I have confirmation that the redirect.bat is run, because the redirect.bat writes a line in a log file.
The vCenter Server app is running under Local System account. Could it be a permissions error? Is LocalSystem allowed to run Powershell scripts?
I now have no clue if the Powershell script even starts, because it (of course) is not visible in my console when running. The batch file always returns errorlevel = 0.
Any tips on how to insert debugging info in the script that should always give output? Tips on how to troubleshoot this?
redirect.bat:
set POWERSHELL=C:\WINDOWS\system32\windowspowershell\v1.0\powershell.exe -nologo -noprofile -noninteractive
SET ERRORLEVEL =
echo %1 > G:\DataStoreAlarms\Log\Redirect-batch.txt
start %POWERSHELL% -command "&"%1""
echo Error level: %ERRORLEVEL% >> G:\DataStoreAlarms\Log\Redirect-batch.txt
I call redirect.bat from the command line and from the app like this:
redirect.bat G:\DataStoreAlarms\Scripts\TestGabrie.ps1
TestGabrie.ps1:
$String = "This is a test"
$String | Out-File -FilePath "G:\DataStoreAlarms\Log\Powershell.txt" -Append

Problem seemed to be the START command:
start %POWERSHELL% -command "&"%1""
After changing it to this, it worked:
%POWERSHELL% -command "&"%1""
Thanks for all your help.
So i have fairly easy powershell script that contains following:
import-module activedirectory
Get-ADUser -Filter *
remove-module activedirectory
If i run it from powershell it runs OK, but when i try to call it from CMD nothing happens, it just opens powershell and thats it. I am using following command to run it:
powershell.exe -file "D:\test.ps1"
I noticed also following thing, 2 powershell.exe processes run after i execute this. If i exit from CMD from one powershell then i start seeing lists that this PS query should be returning. Is there a way to get this working since i am trying to run ps script as scheduled job. The crucial part here is import module when i run it over cmd which is not happening for some reason.
It's powershell 2.0 running on Windows 2008R2. I tried this script on win 2012r2, works fine from CMD... Looks like ps 2.0 limitation?
Could be a couple of things going on here. Since your windows opens and closes you wont get to see any errors that might be occurring. What is your ExecutionPolicy set to? Get-ExecutionPolicy
When I make scheduled tasks of my scripts I usually set up my action as such
Program/Script = %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe
Arguments = -ExecutionPolicy Unrestricted -NoProfile -File C:\data\script.ps1
Start In = %SystemRoot%\system32\WindowsPowerShell\v1.0
Also, I don't believe it matters in this case but be sure you have the script "Running with highest privilege" if required.
As the title suggests, I have an added parameter in my Task Scheduler Actions that logs stdout and stderr to a log.txt file. The logging works when the action is run through the command prompt, but not when the action is run by the actual Task Scheduler (at its specified time). Task scheduler reports the action runs successfully, but I can't be sure it does because there's no logging:)
Command looks like this
powershell.exe -file "D:\Scripts\TimeSync2.ps1" > "D:\Scripts\timeSync_log.txt" 2>&1
I'm unfortunately not a native Windows user, so any help would be appreciated. I'm running Windows Server 2008 R2 Enterprise.
Thanks!
Cmd.exe handles command redirection. You have to run it under cmd.exe. Powershell probably also can do redirection but in your script (.NET can).
A black window just means a console program is running. Only if cmd is running does cmd features become available. By starting cmd or by putting it in a batch you canget redirection from cmd.
cmd /c powershell.exe -file "D:\Scripts\TimeSync2.ps1" > "D:\Scripts\timeSync_log.txt" 2>&1
See for Help
cmd /?
Place the command you listed in a batch file and then schedule the batch file.
If you are doing so and it fails, then try it with your account credentials as authentication in task scheduler, to see if it is a permissions issue.
#echo off
powershell.exe -file "D:\Scripts\TimeSync2.ps1" > "D:\Scripts\timeSync_log.txt" 2>&1
