PowerShell: Is it possible to write a script which refers to files in its folder, which will still work wherever it's called from?

So let's say I have a script at C:\scripts\MyScript.ps1 which is simply:

Get-Content ".\text.txt"

In C:\scripts I also have a file, text.txt, which contains arbitrary text which gets printed when the script is called. This script works fine if I use it when PowerShell's current directory is C:\scripts. However, if PowerShell is currently in a different directory, e.g. C:\otherFolder, then calling the script thusly from the PoSh command window fails:

PS C:\otherFolder> ..\scripts\MyScript.ps1

which I would expect since the reference to text.txt within the script is relative and the file not present in C:\otherFolder. My question is, is there any way to write a script which has relative references to other files, which will still work as intended even if called from within a different folder?

I realize there wouldn't be a problem if the script referred to "C:\scripts\text.txt", but I want to be able to move the script (and it's dependent files) around without having to update the references in the script each time.

Thanks.

I think this related StackOverflow question provides an answer: How to get the current directory of the cmdlet being executed

You'll probably want to use $MyInvocation.MyCommand.Path within your script

try this in your script:

$scriptpath = $MyInvocation.MyCommand.Path
$dir = Split-Path $scriptpath
$path = join-path $dir "text.txt"
get-content $path
