Sm list-disks not found

Question

I am trying to make internal SDcard storage on my new Android device.

I managed to install ADB and Fastboot, although it was not as easy as I hoped, and I had to install them in usr / local / bin instead of usr / bin.

My next step is to run sm list-disks, but when I do, it will return.

adb shell shell@gtexswifi :/ $ sm list-disks /system/bin/sh: sm: not found 127| shell@gtexswifi :/ $ 

I'm not sure what to do next, because I think the path may be wrong and cannot find messages about a similar problem.

Thanks.
