remove what ever comes after “\” using PowerShell

Question

Anyone would help to figure out how to remove the last few characters in PowerShell, for example:

server\instance

need to remove \instance part to become:

server

Do you have anything you have already tried yet? Using a string split on the slash and grabbing the first portion of the array is where I might go with it. — ATek

I'm not sure I completely understand, but if service\instance is a string you could do it with

"server\instance" -replace "\\.*", ""

to replace everything \ and after with an empty string.

One option would be to use Split-Path

Example

Split-Path 'server\instance'

Result

server

This is actually the "best" awnser since the builtin cmdlet split-path is made for this by microsoft.

Use Substring like this:

$s = 'server\instance'
$s.Substring(0, $s.IndexOf('\'))
