I am kicking off a PowerShell script with UiPath. I need to pass an argument in, from UiPath. Firstly is this possible and secondly does anyone have an example of this? Not sure what the syntax is for this in the PowerShell script
Is it possible to pass arguments from UiPath to the terminal.
Your PowerShell script needs to be saved in a txt
file.(PSSampleParameters.txt)
Code sample(PSSampleParameters.txt):
Param(
[string]$computerName
)
[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
[System.Windows.Forms.MessageBox]::Show($computerName)
Add a "Read Text file" activity and on filename add your PowerShell script.
Add "Invoke Power Shell" activity and be sure that you set "ContinueOnError" to True and check "IsScript"
With "Invoke power shell" activity selected go to on right panel and click on "..." button from Parameters. In the screen that will open you can add your parameters.

First of all make sure the path used for powershell is correct (best option in my opinion is to click Browse... and select the program with the dialog window instead of manually inserting the full path, if that's what you did).
In second place, change Add arguments (optional): to -File "D:\TM1 Model\Test GIIS\...\yourfilename.ps1", please note you should use double quote since the full path contains spaces; again, make sure the full file path is typed correctly.
There should be no need to insert the full path in the in the Program/script box. Most people don't even know where it is.
For all the PowerShell scripts that I run on servers I only type powershll.exe and it works.
I agree with Giacomo (Calvin?), the value in the Add Arguements box needs to be in quotes if you have spaces in the folder or file name. ie -File "C:\Batch Files\checkdisk.bat"
The -File argument is telling PowerShell the file you want powershell.exe to run.
I have a powershell one liner that would like to transform on a PS1 file
This question is pretty basic but how do I convert apowershell one liner to PS1?
Thanks
There are a few steps to do this:
Open notepad.
Copy and paste the powershell script into notepad. Now if the one-liner has multiple lines using ; separate them by using enter. You can expand The for, if, while, try blocks like this:
try
{
Anything
}
You can also make the script accept args using $args automatic variable. $args[0], $args[1] .. $args[n] parameters and so on.
Select file menu and save as dialog.
Enter the name of powershell script with extension .ps1 (Example: foo.ps1).
Choose "All files" in the drop down menu.
Click save button. Here you go!
I want to prompt the user for a directory path.
The user can enter some text like C:\Pro in command line, tap tab button and the script should autocomplete the text toC:\Programs\ on another tab it should change the text to C:\Program Files\.
So, the script should scan folders and help user to navigate between them on typing.
Important: I can't use any GUI dialogs, because I am going to use the script on Win with no GUI.
This code will not work:
New-Object System.Windows.Forms.FolderBrowserDialog
Ummm... you don't have to? PS already does that by default?
function T
{
param
(
[System.IO.FileInfo]
$P
)
$P.FullName
}
T -P # Pressing <tab> at this stage will automatically show you the first file in your working directory. That happens even if the P was of type string.
I have been trying to create some registry keys to open PowerShell as you would Command Prompt in explorer by pressing Ctrl+Shift+Right Click.
I have the context key created here:
but the value I put here:
returns an error when I click Open PowerShell here
I've tried a few string values now but still with similar results. Has anyone accomplished this using the background directory key and if so how did you do it?
You will want to use %V instead of %1.
Change the Default value like so:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -NoExit "cd '%V'"
I'm attempting to override and implement my own TabExpansion. In the function I want to parse the contents of $psise.CurrentFile.Editor.Text when a certain $lastword criteria is matched. The issue I have is that the variable $psise.CurrentFile.Editor.Text is resolved to the contents of my TabExpansion function rather than whatever text is in a PowerShell ISE tab.
Here's simple test function. Open an ISE tab and paste the following tabexpansion function definition:
function tabexpansion
{ $psise.CurrentFile.Editor.Text }
Run the script in ISE. Next open another tab in ISE type some text and press the tab key
The output will be
function tabexpansion
{ $psise.CurrentFile.Editor.Text }
Rather than whatever text was in the second tab. Is there any way to get $psise.CurrentFile.Editor.Text to resolve at runtime when used within a tabexpansion function?
As noted in the comments, this appears to be bug in PowerShell ISE. A Microsoft Connect item has been filed.
