Need help with running terminal commands on startup

Question

I made my Zero into a radio transmitter and I am trying to make it transmit on startup, I am not quite sure how to do it, I've looked around different forums but I can't really find anything. I would appreciate it very much if someone would like to help me with this. I am running a lite version of raspbian.

What I want it to do is to open the directory and run the program with a command.

Directory:

radio/fm_transmitter-master/

The command I want it to type out in the directory:

sudo ./fm_transmitter -f 104.0 -r song.wav

I have tried to do something myself in crontab -e and rc.local but I've had no succes.

Please do reply if you know what I can do.

Answer 1

You should use the command sudo crontab -e and make cron start a bash file that contains your fm_transmitter -f 104.0 -r song.wav.

So make a bash file like /home/pi/fm_transmitter -f 104.0 -r song.wav and let crontab run that.
