To pass parameters to a PowerShell script from a batch file, you can use the following syntax:
- In the batch file, call PowerShell with the script file and pass the parameters using the -File flag. For example:
1
|
powershell -File "C:\path\to\script.ps1" -Parameter1 "value1" -Parameter2 "value2"
|
- In your PowerShell script, you can access the passed parameters using the $args or named parameters. For example:
1 2 3 4 5 6 7 |
param( [string]$Parameter1, [string]$Parameter2 ) Write-Host "Parameter 1: $Parameter1" Write-Host "Parameter 2: $Parameter2" |
- Make sure to properly handle any user inputs to prevent any security vulnerabilities or unexpected behavior.
By following these steps, you can easily pass parameters to a PowerShell script from a batch file.
How to use splatting to pass parameters to a PowerShell script?
Splatting is a technique in PowerShell that allows you to pass a collection of parameter values to a command or script as a hashtable. This can make your code more readable and maintainable, especially when dealing with a large number of parameters.
To use splatting to pass parameters to a PowerShell script, you can follow these steps:
- Define a hashtable that contains the parameter names and values that you want to pass to the script. The keys of the hashtable should be the parameter names, and the values should be the parameter values.
1 2 3 4 5 |
$params = @{ Param1 = "Value1" Param2 = "Value2" Param3 = "Value3" } |
- Use the splatting operator (@) to pass the hashtable to the script. You can do this by using the & operator to invoke the script and passing the hashtable as an argument.

|
& "C:\path\to\script.ps1" @params
|
- In the PowerShell script, access the parameters using the automatic variable $args, which represents an array of values that were passed to the script.
1 2 3 4 5 6 7 8 9 |
param( [string]$Param1, [string]$Param2, [string]$Param3 ) Write-Host "Param1: $Param1" Write-Host "Param2: $Param2" Write-Host "Param3: $Param3" |
By using splatting, you can make your PowerShell scripts more flexible and easier to maintain by passing parameters as a hashtable rather than individual values.
How to pass parameters to a PowerShell script?
To pass parameters to a PowerShell script, you can use the $args
array or named parameters. Here's how you can do it:
- Using the $args array: You can access the parameters passed to a script using the $args array. Each parameter will be stored in the array indexes, starting with 0, 1, 2, and so on.
Here's an example of how you can pass parameters using the $args
array in a PowerShell script:
1 2 3 4 5 6 7 |
param( $param1, $param2 ) Write-Host "Parameter 1: $param1" Write-Host "Parameter 2: $param2" |
To run the script and pass parameters:
1
|
.\script.ps1 value1 value2
|
- Using named parameters: You can also define named parameters in your script by using the param keyword. This allows you to specify the parameters explicitly when calling the script.
Here's an example of how you can pass named parameters in a PowerShell script:
1 2 3 4 5 6 7 |
param( [string]$param1, [string]$param2 ) Write-Host "Parameter 1: $param1" Write-Host "Parameter 2: $param2" |
To run the script and pass named parameters:
1
|
.\script.ps1 -param1 value1 -param2 value2
|
Using named parameters is more explicit and can make your script more readable and easier to understand.
How to pass arrays or collections as parameters to a PowerShell script?
To pass arrays or collections as parameters to a PowerShell script, you can use the [array]
type accelerator or the [System.Collections.Generic.List[object]]
type.
Here's an example of how to define a script that takes an array as a parameter:
1 2 3 4 5 6 7 |
param( [array]$myArray ) foreach ($item in $myArray) { Write-Output $item } |
You can then call this script and pass an array as a parameter like this:
1 2 |
$myArray = @("item1", "item2", "item3") .\MyScript.ps1 -myArray $myArray |
Alternatively, you can also use a generic collection like a List
as a parameter in your script:
1 2 3 4 5 6 7 |
param( [System.Collections.Generic.List[object]]$myList ) foreach ($item in $myList) { Write-Output $item } |
And then pass a List
as a parameter like this:
1 2 3 4 5 |
$myList = New-Object System.Collections.Generic.List[object] $myList.Add("item1") $myList.Add("item2") $myList.Add("item3") .\MyScript.ps1 -myList $myList |
Using these methods, you can pass arrays or collections as parameters to a PowerShell script.
How to encode special characters in parameters passed to a PowerShell script?
Special characters in parameters passed to a PowerShell script can be encoded using the backtick (`) character or by enclosing the parameter value in double quotes.
For example, if you need to pass a parameter value that contains a space or a special character such as an ampersand (&) or a dollar sign ($), you can encode it using the backtick character like this:
1
|
.\yourScript.ps1 -paramName "value` with` special` characters"
|
Alternatively, you can enclose the parameter value in double quotes like this:
1
|
.\yourScript.ps1 -paramName "value with special characters"
|
This will ensure that the special characters are correctly passed to the script and processed by PowerShell.
