Run init script as daemon

isuck@linux · 02-09-2007, 11:51 PM

I just added a small script to my init scripts, it basically continuously reads a pipe. If I run this script from the command line without & if freezes my screen and I can't stop it. Now I wonder if the same is going to happen when I reboot. Is there any way to tell the script to run as a daemon directly? TIA

In whatever init file calls your init script, try putting a & after the call to your script.

For example, if your call to your init script says:

Code:

/etc/rc.d/localscripts/mylocalscript

then it should now say:

Code:

/etc/rc.d/localscripts/mylocalscript &

Hope this helps.

Thanks for your answer, I knew that one, but I meant something inside the script so I didn't have to call it with the & at the end.

If you're programming entirely with bash scripts, and you want to start something that continues after the boot process is complete, I don't think you can avoid "&".

It's possible to avoid the &:

#!/bin/bash
if [ "x$1" != "xdaemon" ]; then
$0 daemon &
exit 0
fi

... the rest of your script goes here

Thanks for all the answers. That's what I was looking for alienDog.
