Execute a command when the Linux starts

Hello,
I'm using Debian and want the command tor -f /etc/tor/torrc2 to run automatically when the system reboots. I tried the following two solutions:

1. I created a file called Tor.sh in the /etc/init.d/ directory and put the desired command in it, and then using the chmod +x command, I turned it into executable mode.
2. I put the command in the /etc/rc.local file.

Neither solution worked. What is wrong?

Thank you.
