Need help setting GPU performance to high

I’m trying to set GPU performance to high by the command

sudo echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level

But I’m getting the error

<w> fish: An error while redirecting the file sys/class/drm/card0/device/power_dpm_force_performance_level open: permission denied

Any idea what I’m doing wrong?

I followed this guide to know about this step

I’m on AMD stoney graphics processor and AMD A6-9220 R4 processor

It worked.
I entered sudo su environment and then the command worked, it wasn’t working just by adding sudo before the command in normal user mode
