raspi-config

Hey guys,

I installed the distribution of KODI on my raspberry PI 3. Obviously, sudo raspi-config is not working on it. But I need to configure my Raspberry like it :

1-Expand the root filesystem to have enough space for the cloud
Select “Expand Filesystem”

2- Change user password
“For Security when accessing form the WAN”

3- Change locale to en_US.UTF8
Select “Internationalisation Options”

4- Memory split, allocate xxM to video graphics
Select “Advanced Options” –> “Memory Split”

5- Overclock to Modest or Medium

But I don’t know how to do it without the raspi-config instruction.
I know that kodi have a PI config feature on the osmc menu but I did not find how to do these modifications.

Could you please help me ?

Regards,
