How to show username in Dashboard

I need to display username next to ‘Hello’ in the Dashboard. something like ‘Hello Bob’ instead of ‘Hello Admin!’.
i figured that this is coming from top_bar.tpl, however i have no clue where the values are getting initialized to the variable $userAlias or $userLogin.

Code in top_bar.tpl

{capture assign=helloAlias}{if !empty($userAlias)}{$userAlias}{else}{$userLogin}{/if}{/capture}


However i tried the below with no luck.

in /plugins/userManage/Controller.php => inside userSettings() function,

$view->userAlias = ‘value from session variable’; (no luck with this…)

in the Dashboard it is still showing ‘hello Admin!’

Any help is appriciated.
