auto run script while boot up

[afreenmusarrath23]

hi 

i'm facing issue in running simple script while boot up on imx8mm mini board

these are the changes i have made 

in init.imx8mm.rc --> 

on property:sys.boot_completed=1
start init-myservice-sh

service init-myservice-sh /vendor/bin/sh /vendor/bin/init.myscript.sh
class main
user root
group root system
disabled
oneshot

in evk8mm.mk

#Script
PRODUCT_COPY_FILES += \
device/fsl/imx8m/evk_8mm/init.myscript.sh:$(TARGET_COPY_OUT_VENDOR)/bin/init.myscript.sh

and my script is in vendor/bin/

what else changes do i need to make for running a script automtically
