在init.rc中回显

Question

hi I want to add these scripts to init.rc but I get the error that init.rc doesnt support echo.

echo device > /sys/devices/platform/usbc.0/mode

what is the right way to do such a thing in init.rc?

Answer 1

You could probably use write for that. Something like:

write /sys/devices/platform/usbc.0/mode ${device}

Or if you literally want to write the string "device":

write /sys/devices/platform/usbc.0/mode "device"
