create a line automatically at every reboot

bhert · 04-04-2007, 02:37 PM

Hello, I have a problem, I installed quake for linux and there was no sound at start of the game. I found out that if i add a line: echo fuhquake-gl.glx 0 0 direct > /proc/asound/card0/pcm0p/oss in /proc/asound/card0/pcm0p/oss, the game works with sound. The only problem is when I reboot, the line is gone from the file. What is the best way to have the line added to the file automatically when I reboot? Do I create an autostart script? I don't think the .kde/autostart will work because you have to be root to do this. I could be wrong. Help please. I don't want to have to add the line manually everytime I boot. Thanks.

sysctl is your friend.

See man sysctl for more info

Put it in the rc.local file is one way:

Code:

if [ -d /proc/asound/card0/pcm0p ]; then
  echo "fuhquake-gl.glx 0 0 direct" > /proc/asound/card0/pcm0p/oss
fi

I may be wrong, but I don't think that's relevant here. From man sysctl:

"sysctl is used to modify kernel parameters at runtime. The parameters available are those listed under /proc/sys/."

The OP wants to edit the /proc/asound branch.

sorry my bad

Thanks for replying bsdunix, I am using suse so there is no rc.local in /etc/init.d
However, there is rc in /etc/init.d which contains rules for daemons. Can I add the line to it?
Thanks,

If there is no rc.local in /etc or /etc/rc.d (if you have
a /etc/rc.d), then use /etc/init.d/boot.local file. It's
been a long while since I used SuSE. Apparently,
boot.local is the replacement for rc.local file.

bsdunix, I do have boot.local in etc/init.d
I added the script and it wouldn't work after I rebooted
I even added my command and still didn't work

What could be wrong?
Is there another way it can be accomplished? Thanks

*EDIT* Could it be permissions? boot.local is set at 744

I installed OpenSUSE 10.2 (very nice) and sure enough the darn boot.local file won't work. After much trial and error I was able to get it to work using after.local file (which I had to create). I found out about that file by looking at the /etc/init.d/rc script.

Code:

# cd /etc/init.d
# touch after.local
# chmod 744 after.local
# vi after.local

Enter the following text, save, and reboot:

Code:

#! /bin/sh
#
# /etc/init.d/after.local
#
#
# Here you should add things, that should happen directly
# after run level is reached.
#

if [ -f /proc/asound/card0/pcm0p/oss ]; then
  echo "fuhquake-gl.glx 0 0 direct" > /proc/asound/card0/pcm0p/oss
fi

Verify it worked:

Code:

# cat /proc/asound/card0/pcm0p/oss
fuhquake-gl.glx 0 0 direct

I hope you have success now.

Thanks so much bsdunix

You are a lifesaver! Now I can add other scripts and make things easier for me.

I looked at rc with vim and used search and sure enough after.local is there

I looked at boot.local and it starts before the first runlevel. That's why it didn't work

after.local starts after the runlevels are done. That's why it works.

It takes a little time to get used to suse, but it's a very nice distro. Glad you like it too.

Once again, thanks for all your help

Cheers
