How to autorun commands at boot?

Hi all,

I am a newbie using Redhat Linux Enterprise 5.0.
I am trying to figure out how to autorun these commands at boot.

cd ixpio
./ixpio.inst

Please advice.

Thanks.

Using an editor as root or sudo, put those commands in /etc/rc.local. Make sure there is no hash "#" at the beginning or they will be ignored.

What are these commands? Is this a service? Is it a graphical program? Is this a user program or a system program?
If this is a user program, it is better to start it when you log in instead of when your computer boots.
If this is a user console program, then your .profile script is a good place to start it, but you may need to run it in the background so that the .profile script will finish. If this is a GUI program, placing a shortcut in an Autostart directory may be better. If you want it to start regardless of which desktop environment you use, then an X script such as .xsession.

Also, include a full path to the command in your scripts. A script started at boot and run as root will have a different environment then one started by a regular user.

it is an I/O module slotted in one of my PCI-Express slot. It doesnt load automatically with every boot. To load the module i have to type the commands in the command shell.

Any advice?

Hi Brains,

i have tried insert these commands in rc.local but it doesnt work.
When i typed "lsmod" in the command shell, my I/O module is not loaded.

please advice.

Where exactly is this "ixpio" directory?
If it's in your home directory, specify the full path of this directory, an example below using my /etc/rc.local file.

Code:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
cd /home/me/ixpio
./ixpio.inst

exit 0

You can also put them both in one command as such: cd /home/me/ixpio && ./ixpio.inst

Could you provide a link with more information on this device and the program? A README file would be great.

Does it work when you run it manually? The only way I can see this is if it is using the fuse system to load a userland driver.

A user program to load a kernel module just doesn't sound right. I can see running a script as root to install the kernel module in /lib/modules/$(uname -r)/ and then adding a file in /etc/modprobe.d/ with an install command, modprobing the device and running "depmod -a".

Perhaps this has been done previously and the ixpio.inst command does something else than load the module.
In that case, the problem could have been in the previous phase of installation.

Is ixpio.inst a script? If so, what does it do?
