Call PowerShell script PS1 from another PS1 script inside Powershell ISE

Question

I want call execution for a myScript1.ps1 script inside a second myScript2.ps1 script inside Powershell ISE.

The following code inside MyScript2.ps1, works fine from

Answer 1

The current path of MyScript1.ps1 is not the same as myScript2.ps1. You can get the folder path of MyScript2.ps1 and concatenate it to MyScript1.ps1 and then execute it. Both scripts must be in the same location.

## MyScript2.ps1 ##
$ScriptPath = Split-Path $MyInvocation.InvocationName
& "$ScriptPath\MyScript1.ps1"

Answer 2

One line solution:

& ((Split-Path $MyInvocation.InvocationName) + "\MyScript1.ps1")

Answer 3

To execute easily a script file in the same folder (or subfolder of) as the caller you can use this:

# Get full path to the script:
$ScriptRoute = [System.IO.Path]::GetFullPath([System.IO.Path]::Combine($PSScriptRoot, "Scriptname.ps1"))

# Execute script at location:
&"$ScriptRoute"

Answer 4

This is just additional info to answers in order to pass argument into the another file

Where you expect argument

PrintName.ps1

Param(
    [Parameter( Mandatory = $true)]
    $printName = "Joe"    
)


Write-Host $printName

How to call the file

Param(
    [Parameter( Mandatory = $false)]
    $name = "Joe"    
)


& ((Split-Path $MyInvocation.InvocationName) + "\PrintName.ps1") -printName $name

If you do not do not provide any input it will default to "Joe" and this will be passed as argument into printName argument in PrintName.ps1 file which will in turn print out the "Joe" string

Answer 5

I had a problem with this. I didn't use any clever $MyInvocation stuff to fix it though. If you open the ISE by right clicking a script file and selecting edit then open the second script from within the ISE you can invoke one from the other by just using the normal .\script.ps1 syntax. My guess is that the ISE has the notion of a current folder and opening it like this sets the current folder to the folder containing the scripts. When I invoke one script from another in normal use I just use .\script.ps1, IMO it's wrong to modify the script just to make it work in the ISE properly...
