I am attempting to redirect output of a Powershell script to a txt file.
In the Powershell window, I try:
.\script.ps1 > list.txt
But it does not help, all output still gets printed to the window.
I then tried:
.\script.ps1 >& list.txt
And got this error:
Missing file specification after redirection operator.
At line:1 char:21
+ .\script.ps1 > <<<< & list.txt
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : MissingFileSpecification
If you are writing output in script.ps1 using Write-Host (or [Console]::WriteLine) you will either need to change those to Write-Output or do this:
powershell.exe -File test.ps1 > out.txt
By the way > is syntactic sugar for Out-File, they are the same thing.
If the output you're wanting to capture is being written to the console using Write-Host, you need to change that to Write-Output.
You don't need the & after the >. It is only used to execute something.
.\script.ps1 > list.txt
If script.ps1 is outputting using Write-Host or [Console]::WriteLine you will need to update it.
Here is an example of updating a Write-Host script to be outputable.

I'm using a third party tool to do some AD manipulation. I run a powershell script and pass arguments to it.
Everything works except if that argument contains an apostrophe in it like Jerry O'Connor. I've tried lots of different escape combinations without any luck.
Here is my command: script.ps1 -name "'%name%'" and name contain is Jerry O'Connor.
The error is
Result:The string is missing the terminator: '.
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : TerminatorExpectedAtEndOfString
I've tried:
script.ps1 -name "'%name%'"
script.ps1 -name \"%name%\"
script.ps1 -name ''name''
all with same error.
If you run this at the PS CMD level you'll see the error
powershell echo -name "'Jerry O'Connor'"
Anyone know how to pass an argument to script.ps1 -name "name" where that argument contains an apostrophe?
Cheers
You need to escape any ' chars. inside the value of %name% as '' to make them work inside a single-quoted PowerShell string, which from cmd.exe you can do with %name:'=''%:
From cmd.exe / a batch file:
powershell.exe -Command ./script.ps1 -name "'%name:'=''%'"
If %name% contains verbatim Jerry O'Connor, the above expands to the following, which should work as intended:
powershell.exe -Command ./script.ps1 -name "'Jerry O''Connor'"
However, you can simplify quoting if you use the -File CLI parameter instead of -Command:
powershell.exe -File ./script.ps1 -name "%name%"

Try the escape character as shown here:
$Test = "`'test`'"
$Test
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'.

+ Invoke-Command $licengegen "$inputtest" "$outputtest"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Invoke-Command], ParameterBindingException
+ FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.InvokeCommandCommand
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 redirect the STDERR and STDOUT to two separate files.
I tried the following:
This will output error only to an error file:
powershell.exe -file c:\test.ps1 2> test.txt
This will output all output to a result file:
powershell.exe -file c:\test.ps1 2>&1> test.txt
My question is how can I redirect STDERR and STDOUT to two separate files by running powershell.exe just once?
You can specify multiple redirections. Ex.
powershell.exe -file Sample.ps1 2>errors.txt 1>output.txt
Sample.ps1
Write-Error "This is a critial error"
Write-Output "This is output"
"This is also output"
Errors.txt
C:\Users\frode\Desktop\Sample.ps1 : This is a critial error
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Untitled202.ps1
Output.txt
This is output
This is also output
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 have a script that is being called a certain way, i cannot change it.
I want to redirect the error messages from the entire script to a file. How does this work?
I did this, which works, except the errors are complete gone:
$ErrorActionPreference="SilentlyContinue"
Start-Transcript -path C:\output.txt -append
write-host "test"
some nonsence that creates as error
Stop-Transcript
Thanks
Would this work for you?
try{
# your code goes here
}
catch{
$exception = $_.Exception.Message
Out-File -FilePath 'c:\myscript.log' -Append -InputObject $exception
}
Since Powershell 5.1, there are "Redirectable output streams"
with bash-like similar syntax, e.g.
Write-Output "good" > success.txt
Write-Error "failed" 2> error.txt
Write-Warning "attention" 3> warning.txt
You can also redirect error to success stream.
./script.ps1 2>&1 > out.log
Alternatively, to redirect all streams when running a script or command, use
.\script.ps1 *> $null # suppress all output
See about_Redirection for more details.
I needed something like this before, but i could change how the file is being called etc.
If its launched from commandline as mentioned, by arco444, you can use the below to pipe everything to one file:
PowerShell.exe -Command "& {c:\myscript.ps1}" > c:\myscript.log
Beware using Start-Transcript. You might get the following error:
Start-Transcript : This host does not support transcription.
