how output ps aux | grep aUser and keeping Newline ?

Hi,

by doing a

 bash

    
ps aux | grep UserName


  

The output do not keep the LF[^1] 😡

I've found some solution online by they involve 3 or more pipe | !

On my side, I've made this

 bash

    
ps -fp $(pgrep -d, -u UserName)


  

But still I found it not super human readable.

Is their a native way with ps to filter users ? or to grep it but the keep the LF ?
