Regular Expression, remove everything after last forward slash

Question

I\'m trying to use a regular expression within PowerShell to remove everything from the last slash in this string;

 NorthWind.ac.uk/Users/Current/IT/Surname,         


        

Answer 1

Here's a solution that doesn't require regular expressions:

PS> $cn = 'NorthWind.ac.uk/Users/Current/IT/Surname, FirstName' -split '/'
PS> $cn[0..($cn.count-2)] -join '/'
NorthWind.ac.uk/Users/Current/IT
