The default user on OSMC is osmc with its home directory being /home/osmcso you would need to change all occurrences of /home/pi by it
yeap , you right its work now Thank You 
sort , thank you
hello one more thing , how to delete old script from startup and add another one?
Which startup and how did you add it to there?
Auto start the clock.py example
Sometimes you a script to start automatically, so you don’t have to login each time to start the script. The binary clock script is a perfect one to do this with.
So follow this simple guide to have the binary clock start when you plug your Raspberry Pi in:
After following the Installation instructions and having run the test script:
Make the piglow directory if not already done:
mkdir /home/pi/piglow
cd /home/pi/piglow
Download the clock.py script into the /home/pi/piglow folder:
wget https://raw.github.com/Boeeerb/PiGlow/master/piglow.py
wget https://raw.github.com/Boeeerb/PiGlow/master/Examples/clock.py
Next create the init.d file, so change to the /etc/init.d folder
cd /etc/init.d
Now create the file
sudo nano clock
And paste the following
#!/bin/sh
/etc/init.d/test
BEGIN INIT INFO
Provides: clock
Required-Start: $remote_fs $syslog
Required-Stop: $remote_fs $syslog
Default-Start: 2 3 4 5
Default-Stop: 0 1 6
Short-Description: Simple script to auto start binary clock
Description: Simple script to auto start binary clock
END INIT INFO
case “$1” in
start)
sudo python /home/pi/piglow/clock.py &
;;
stop)
killall python
;;
*)
exit 1
;;
esac
exit 0
Ctrl + x and Y to save, notice there is no file extension
Now make the file executable
sudo chmod +x clock
And add the clock to the startup scripts
sudo insserv clock
Try it out without restarting
sudo /etc/init.d/clock start
After you have observed it starting, we should be safe to reboot
sudo reboot
To be honest not sure if it was necessary to copy the whole thing into the post you could just point out to the instructions you followed.
Anyhow if you copy something like that into your posts use the peformatted text button </> to make it appear readable.
Now coming to your question, first using init.d scripts is a bit outdated for OSMC so you might want to check if you can transform that into a service based start script.
To remove your clock script you could try sudo update-rc -f clock remove
Adding another service to startup follow the instructions and exchange clock with whatever script you have in mind.
ok thanks will try to do it
