Chaning Username in Terminal

[Coyote]

Hello all,

Sorry if i already missed the posting but I have been trying to change the username in the terminal from somthing other than pine64@pinebook. I have changed my name on login but in the terminal still keep the old username. I also tried using:

Code:

    usermod -l newname pine64

and i get the message:

Code:

    usermod: user pine64 is currently used by process 941

The number at the end changes but I get the message everytime I have tried.

Is is possible to make this modification?

Thank you,

Coyote
