Question about running programs when Pi starts up

[Stille]

Hi,
I need to run 3 programs at the same time when Rasp Pi starts up, and those 3 programs will keep running (forever, ). How could I do that?

Someone told me I could write some script in the "rc.local " to run programs when starting up, but that seems to run programs one by one (start another program when one program ends).

Could anyone give me any suggestions?
Thank you!

Put an & at the end of each command you want to run.

Not sure if it works for multiple programs - but I use cron to run a script on boot. RaspberryPiSpy has a good guide:

Daemon coding is not that difficult though needs some care and most of all comprehensible log files.

To have programs (python or /bin/sh) run at boot and stay running is sort of an art form.

adding the line

nohup /path/to/command 2>&1 > /tmp/programlog &

works in most cases. If it fails to start and run, most issues will be recorded in the logfile.
