I need to call a ps1 Script during going through another ps1 file. The new call shouldn't interrupt the script which I'm going through. Also I always call the Powershell scripts like this: powershell -ExecutionPolicy Bypass -File file.ps1 -param log_14.txt due to execution policies.
I tried following code in my .ps1 script, sadly it doesn't work:
Start-Job PowerShell -Argument "sort.ps1 -file $fileName"
Any ideas how to make it work?
Try this:
$job = Start-Job -ScriptBlock {
powershell -ExecutionPolicy Bypass -File "filepath.ps1 Param"
}
$job | wait-job | receive-job

The following script works fine in Powershell:
Set-ExecutionPolicy Bypass -Scope Process -Force; Invoke-Webrequest
'https://blah.blob.core.windows.net/laps/AutoAutoPilot.ps1' -OutFile
C:\script.ps1; C:\script.ps1
I'm trying to convert it so that it runs as a CMD/BAT file. I simply need to double click to run it. I need the CMD/BAT file to run Powershell as administrator and from there, it will run the script from above. Here's what I have. It'll just quit straight away without doing anything.
powershell -ExecutionPolicy Bypass -c Start-Process -Verb RunAs -Wait
powershell.exe '-ExecutionPolicy Bypass -Noexit -c Set-Location
"\"\\\"%CD%\\\"\""; -c "& Invoke-Webrequest
\"https://blah.blob.core.windows.net/laps/AutoAutoPilot.ps1\"
-OutFile C:\script.ps1; C:\script.ps1" '
Update:
I got it working now. The full output looks like this:
powershell -Command "& ({Start-Process powershell -Verb RunAs -ArgumentList '-ExecutionPolicy Bypass -NoExit -Command Invoke-WebRequest -Uri https://blah.blob.core.windows.net/laps/AutoAutoPilot.ps1 -OutFile C:\script.ps1; C:\script.ps1'})"
If you use the -NoExit parameter when starting powershell.exe PowerShell should not close after the script has finished running. Afterwards if you do not see errors, you can look at the $error variable, to see any errors which occurred when running your script.
You are trying to run your PowerShell code, using PowerShell.exe from command prompt, so you should be able to use the same code as you did before, when you were running your code directly in PowerShell before.
To my understanding you want to run powershell code in a batch-file.well Depending upon your preference there are multiple solutions to this problem(well i haven't checked any of them):
Solution:1
make a batch file and give your powershell script to it as a parameter.
Without Admin access:
#ECHO OFF
PowerShell.exe -NoProfile -ExecutionPolicy Bypass -Command "& '%~dpn0.ps1'"
PAUSE
With Admin access:
#ECHO OFF
PowerShell.exe -NoProfile -Command "& {Start-Process PowerShell.exe -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File ""%~dpn0.ps1""' -Verb RunAs}"
PAUSE
Solution:2
If you don't want an external .ps1 file,then you can try this.just save it as something.bat
powershell -command if ($true)^
Set-ExecutionPolicy Bypass -Scope Process -Force; Invoke-Webrequest 'https://blah.blob.core.windows.net/laps/AutoAutoPilot.ps1' -OutFile C:\script.ps1; C:\script.ps1^
This should do the trick:
powershell -Command "& {Start-Process powershell -Verb RunAs -ArgumentList '-ExecutionPolicy Bypass -NoExit -Command Set-Location -Path C:\whatever\working\directory\you\need; Invoke-WebRequest -Uri https://blah.blob.core.windows.net/laps/AutoAutoPilot.ps1 -OutFile C:\script.ps1; C:\script.ps1'}"
Explanation:
When executing commands in PowerShell using the -Command argument, ExecutionPolicies do not apply as your are executing a single command and not a script. Even the execution of a scriptblock consisting of multiple commands counts as the execution of a single command. That's why you can directly call PowerShell from the command prompt like this (without anything else):
powershell -Command ...
-Command expects - to read from stdin or a scriptblock (read more). Scriptblocks have to be enclosed in curly braces ({...}). If you pass a scriptblock from the command prompt to PowerShell, you also have to add the call operator &:
powershell -Command "& {...}"
As you need an elevated PowerShell, you start a new PowerShell process from the previous PowerShell with Start-Process in combination with the -Verb RunAs argument. You add all arguments that you want to pass to the elevated PowerShell to the -ArgumentList argument:
... Start-Process powershell -Verb RunAs -ArgumentList '...' ...
As you want to call a script file, you now need the corresponding ExecutionPolicy. If you don't want to change it on the system, you can bypass the ExecutionPolicy with -ExecutionPolicy Bypass as you already did. And you also add -NoExit here. To pass your desired PowerShell commands, you use the -Command argument again. This time, you don't need the call operator and you can also omit the curly braces as we are now in PowerShell and not in the command prompt anymore.
... -ExecutionPolicy Bypass -NoExit -Command Set-Location -Path C:\whatever\working\directory\you\need; Invoke-WebRequest -Uri https://blah.blob.core.windows.net/laps/AutoAutoPilot.ps1 -OutFile C:\script.ps1; C:\script.ps1 ...
I have this batch file which runs the powershell script.
I want to run it the background but if I run with "windowstyle hidden" still visible.
powershell -ExecutionPolicy ByPass -windowstyle hidden -File "C:\script.ps1"
You can run, e.g. long running scripts, as a jobs.
To start it you run
$job = Start-Job -ScriptBlock {Get-Process}
this will start the Get-Process cmdlet in the background. The script can be also some custom made script or a longer script, it doesn't need to be a one-liner.
You can check its status by running
$job | Get-Job
and to receive the output you run
$job | Receive-Job
just note that once the data is received, it's lost. You can only receive it once, after that it's up to you to save it in a variable or later processing.
Finally to remove the job from the queue you run
$job | Remove-Job
I use the following function:
function bg() {
Start-Process `
-WorkingDirectory (Get-Location) `
-NoNewWindow `
-FilePath "powershell" `
-ArgumentList "-NoProfile -command `"$args`" "
}
It starts a new powershell instance which is executed in background and allows the usage of cmdlets.
You call it like:
bg "Start-Sleep 2; get-location; write 'done' "
I tried to launch a long powershell script with the name "long name here.ps1" from command prompt. But I am also trying to ensure that it runs as an administrator command in powershell. I have all execution policies in powershell set accordingly I used the ss64 set-executionpolicy command guide for powershell to get powershell working. But I am trying to use the solution from another stackoverflow question that talks about running commands as administrator. I am running a batch script that needs to execute a powershell script (.ps1) as admin, and I don't mind if the user is prompted by UAC or for the password. I am currently using the following command:
powershell.exe -command "&{ Start-Process powershell -ArgumentList '-noprofile -file "C:\long name here.ps1"' -verb RunAs}"
I found this command at https://ss64.com/ps/powershell.html at the bottom where there are details on how to run a powershell command as administrator. The problem with that code is that my powershell script 1. has arguments, and 2. has a long name. I have tried many different iterations of this command with no success, and the ones that DON'T work are listed below:
powershell.exe -command "&{ Start-Process powershell -ArgumentList '-noprofile -file C:\long` name` here.ps1' -verb RunAs}"
powershell.exe -command "&{ Start-Process powershell -ArgumentList '-noprofile -file:"C:\long name here.ps1' -verb RunAs}"
Also, I am completely lost as to how to send arguments to the actual script.
If I'm reading your question correctly - powershell wont find the file as it stops reading the path name when it encounters a blank space?
The example given here specifies that; powershell commands to be run from command prompt as an administrator should have the following syntax:
powershell.exe -noprofile -command "&{ start-process powershell -ArgumentList '-noprofile -file MyScript.ps1' -verb RunAs}"
Couple of ways to achieve what you're looking for. But the easiest method would be to escape the quotes using a ` character. So something similar to;
powershell.exe -noprofile -command "&{ start-process powershell -ArgumentList '-noprofile -file `"C:\long file name.ps1`"' -verb RunAs}"

Use a Freeware Third Party Utility
If a freeware third-party executable is permissible, you can use a short tool I wrote called elevate32.exe (32-bit) and elevate64.exe (64-bit) to launch powershell.exe as administrator with the -File parameter and the script arguments you want to use:
elevate64 -- powershell.exe -File "<path>\<long script name>.ps1" -Arg "<long script argument>"
You can get the tool from www.westmesatech.com (copyrighted freeware, free to use anywhere, no installation needed).
Use a WSH Script
If you can't use an external executable, you can also do this (although it does not handle quoting in as robust a manner as the elevate tool's -- parameter) using a Windows Script Host (WSH) script, elevate.js:
var args = WScript.Arguments;
if ( args.Length >= 1 ) {
var exec = args.Item(0);
var cmdLine = "";
for (var i = 1; i < WScript.Arguments.Length; i++ ) {
cmdLine += cmdLine == "" ? '"' + args.Item(i) + '"' : ' "' + args.Item(i) + '"';
}
var shellApp = new ActiveXObject("Shell.Application");
shellApp.ShellExecute(exec, cmdLine, "", "runas");
}
You can call as follows:
wscript.exe "d:\path\elevate.js" powershell.exe -File "C:\long path\script name.ps1" "long script argument"
Self-Elevate your PowerShell Script
Another option is to write a self-elevating PowerShell script. You can check for elevation in the script; if not elevated, it can launch itself elevated and run any command you need. Example:
$isElevated = ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)
if ( -not $isElevated ) {
Start-Process powershell.exe "-File",('"{0}"' -f $MyInvocation.MyCommand.Path) -Verb RunAs
exit
}
& "d:\long path name\script name.ps1" "Long Argument 1" "Long Argument 2"
When you use PowerShell.exe -Command you don't need to use quotes. For example, you can run the following:
PowerShell.exe -Command Get-Service 'wuauserv'
Everything after -Command is interpreted as the command. Note also that double quotes in CMD need escaping with a backslash. Therefore:
powershell.exe -Command Start-Process PowerShell -ArgumentList '-NoProfile -File \"C:\long name here.ps1\"' -Verb RunAs
If your file has arguments:
powershell.exe -Command Start-Process PowerShell -ArgumentList '-NoProfile -File \"C:\long name here.ps1\" \"Arg1\" \"Arg2\"' -Verb RunAs
In Powershell, I created a ScheduledJob using the command Register-ScheduledJob -ScriptBlock {...}. This ScheduledJob executes a ScriptBlock. How can I retrieve the name of the currently running ScheduledJob from the ScriptBlock?
E.g.
Register-ScheduledJob -ScriptBlock { $CurrentScheduledJob | Out-File -FilePath ScheduledJob.txt}
The task in the Windows Task Scheduler is running the command:
powershell.exe -NoLogo -NonInteractive -WindowStyle Hidden -Command
"Import-Module PSScheduledJob; $jobDef =
[Microsoft.PowerShell.ScheduledJob.ScheduledJobDefinition]::LoadFromStore('asdfdsafsdf',
'C:\Windows\system32\config\systemprofile\AppData\Local\Microsoft\Windows\PowerShell\ScheduledJobs');
$jobDef.Run()"
I tried to save the variable $jobDef but it is empty.
Thank you
I ran a ScheduledJob and exported all variable and environment variable and did not find the name or id of the job.
I found a work around:
$jobName = 'testName'
Register-ScheduledJob -ScriptBlock { param($name)
$name | out-file C:\name.txt
} -name $jobName -ArgumentList #($jobName)
If using a parameter is not a solution for you, and you absolutely must retrieve it at run time, then this is a feature request. You can ask for this at the PowerShell user voice
Ok something so simple is just not working for me. I got a cmdlet that accepts a single parameter. I am trying to call a cmdlet within a Windows batch file. The batch file contains:
cd %SystemRoot%\system32\WindowsPowerShell\v1.0
powershell Set-ExecutionPolicy Unrestricted
powershell 'C:\convert-utf8-to-utf16.ps1 C:\test.txt'
powershell Set-ExecutionPolicy Restricted
pause
My ps1 file again not doing anything special:
function convert-utf8-to-utf16 {
$tempfile = "C:\temp.txt"
set-ExecutionPolicy Unrestricted
get-content -Path $args[0] -encoding utf8 | out-file $tempfile -encoding Unicode
set-ExecutionPolicy Restricted
}
When i execute the bat file it just runs to completion (no error messages) and it does not appear to create the temp.txt file.
I can run the powershell command file at the PS command prompt but not in cmd!
Anyone got any ideas what could be wrong?
Starting with Powershell version 2, you can run a Powershell script like so...
powershell -ExecutionPolicy RemoteSigned -File "C:\Path\Script.ps1" "Parameter with spaces" Parameter2
Now if I could only figure out a way to handle dragging and dropping files to a Powershell script.
I explain both why you would want to call a PowerShell script from a batch file and how to do it in my blog post here.
This is basically what you are looking for:
PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& 'C:\convert-utf8-to-utf16.ps1' 'C:\test.txt'"
And if you need to run your PowerShell script as an admin, use this:
PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File ""C:\convert-utf8-to-utf16.ps1"" ""C:\test.txt""' -Verb RunAs}"
Rather than hard-coding the entire path to the PowerShell script though, I recommend placing the batch file and PowerShell script file in the same directory, as my blog post describes.
The problem is in the ps1 file - you declare a function but you don't call it.
I would modify it like this:
param($path)
function convert-utf8-to-utf16 {
$tempfile = "C:\temp.txt"
set-ExecutionPolicy Unrestricted
get-content -Path $args[0] -encoding utf8 | out-file $tempfile -encoding Unicode
set-ExecutionPolicy Restricted
}
convert-utf8-to-utf16 $path
it will work. However, it is not needed, you can simply ommit the function declaration and move the body into the script itself:
param($path)
$tempfile = "C:\temp.txt"
set-ExecutionPolicy Unrestricted
get-content -Path $path -encoding utf8 | out-file $tempfile -encoding Unicode
set-ExecutionPolicy Restricted
# Test-Args.ps1
param($first, $second)
write-host $first
write-host $second
Call from Command Prompt:
PowerShell.exe -NoProfile -Command "& {./Test-Args.ps1 'C:\Folder A\One' 'C:\Folder B\Two'}"
What's confusing is that if the script is in a folder path containing spaces, PowerShell doesn't recognize the script name in quotes:
PowerShell.exe -NoProfile -Command "& {'C:\Folder X\Test-Args.ps1' 'C:\Folder
A\One' 'C:\Folder B\Two'}"
But you can get around that using something like:
PowerShell.exe -NoProfile -Command "& {set-location 'C:\Folder X';./Test-Args.ps1 'C:\Folder
A\One' 'C:\Folder B\Two'}"
Don't use spaces in your .PS1 file name, or you're outta luck.
I got this working...The ps1 file does not need to be wrapped into a function. Just this declaration is ok.
$tempfile = "C:\temp.txt"
get-content -Path $args[0] -encoding utf8 | out-file $tempfile -encoding unicode
and the bat file calls it like:
cd %SystemRoot%\system32\WindowsPowerShell\v1.0
powershell Set-ExecutionPolicy Unrestricted
powershell "& 'C:\convert-utf8-to-utf16.ps1 C:\test.txt' 'C:\test.txt'"
powershell Set-ExecutionPolicy Restricted
pause
Try this syntax instead:
cd %SystemRoot%\system32\WindowsPowerShell\v1.0
powershell {Set-ExecutionPolicy Unrestricted}
powershell "& C:\convert-utf8-to-utf16.ps1 C:\test.txt"
powershell {Set-ExecutionPolicy Restricted}
pause
