    Hello scripting fans,

    I neer your help. I need to select string from string below.

    $mail=@{mail=peter.novak@concon.com}

    I need to get only string

    $prefix="peter.novak"

    I have tried to use [regex] but I was not succesfull, becasue I dont know what expression should be there for selecting string.

    Thanks

    This does the trick:

    "mail=peter.novak@concon.com" | foreach-object { [regex]::split($_,'^mail=|@.+$')[1] }

    To explain what it does, it matches on mail= and @, and splits based on that. By using the [1] you select the value of Peter Novak. If you would omit the [1] you would get two empty lines before and after peter.novak.

    It works 

    $mail | foreach-object { ([regex]::split($_,'^@{mail=|@'))[1] }

    Thanks Jaap

    Hello Liibas,

    I am not sure what you are trying to do exactly, the emailaddress is not a standard AD attribute, are you using custom AD attributes? Also what is the background of what you are trying to do?

    Since you mention using get-aduser here is an example of get-aduser to extract the mail attribute and then use regex to select the username:

    get-aduser jaapbrasser -property mail | select-object -expandproperty mail | 
foreach-object { ([regex]::split($_,'@.+$'))[0] }
