How to automatically execute a script at start-up ?

[micro_sucks]

Hello, I was wondering is someone could help me find out how to execute a specific script at startup every time my computer boots up. I would prefer to execute it as root, but as long as it works. I want it to do the following :

su server1
cd /home/server1/hlds_l
screen -A -m -d -S mypub ./hlds_run -game cstrike +ip ****** +map de_dust +maxplayers 20 -pingboost 1
exit
su server2
cd /home/server2/hlds_l
screen -A -m -d -S mypriv./hlds_run -game cstrike +ip ****** +map de_dust -pingboost 1 +maxplayers 12
exit



that is all I want it to do. Any help would be greatly appreciated. Thanks.

Well, to make it neater, create that as a seperate script somewhere (if you have no idea, go /usr/local/bin/myscriptnamehere or something), chmod +x filename it, and then add it to the startup script:

For Redhat, maybe Mandrake (not sure, haven't used it):

edit: /etc/rc.d/rc.local
or /etc/rc.local

(usually symlinked together.)

Put the line

/usr/local/bin/myscriptnamehere &

at the end of the file. It'll run as root whenever you boot up.


If you use another distro, post the name here and I'll help. (Or try to.)
If you're running into difficulties find rc.local, look around for a S99* file in /etc/init.d

Hope that helps,

Robbo

Sorry i found it, too late in the night for me =( anyway here is the file content :

#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

[ -f /etc/sysconfig/msec ] && source /etc/sysconfig/msec
[ -z "$SECURE_LEVEL" ] && SECURE_LEVEL=3

# Source functions
. /etc/init.d/functions

if [ -f /etc/mandrake-release -a $SECURE_LEVEL -lt 4 ]; then
    R=$(cat /etc/mandrake-release)

    arch=$(uname -m)
    a="a"
    case "_$arch" in
	    _a*) a="an";;
	    _i*) a="an";;
    esac
    
    NUMPROC=`egrep -c "^cpu[0-9]+" /proc/stat`
    if [ "$NUMPROC" -gt "1" ]; then
        SMP="$NUMPROC-processor "
	[ "$NUMPROC" = "2" ] && \
	SMP="Dual-processor "
        if [ "$NUMPROC" = "8" -o "$NUMPROC" = "11" ]; then
            a="an"
	else
	    a="a"
        fi
    fi

    # This will overwrite /etc/issue at every boot.  So, make any changes you
    # want to make to /etc/issue here or you will lose them when you reboot.

    if [ -x /usr/bin/linux_logo ];then
	/usr/bin/linux_logo -c -n -f | sed -e 's|\\|\\\\|g' > /etc/issue
	echo "" >> /etc/issue
    else
	> /etc/issue
    fi
    echo "$R" >> /etc/issue
    echo "Kernel $(uname -r) on $a $SMP$(uname -m) / \l" >> /etc/issue
    
    if [ "$SECURE_LEVEL" -le 3 ];then
	echo "Welcome to ${HOST}" > /etc/issue.net
	echo "$R" >> /etc/issue.net
	echo "Kernel $(uname -r) on $a $SMP$(uname -m)" >> /etc/issue.net
    else	
	echo "Welcome to Mandrake Linux" > /etc/issue.net
	echo "-------------------------" >> /etc/issue.net
    fi
elif [ $SECURE_LEVEL -ge 4 ]; then
    rm -f /etc/issue /etc/issue.net
fi

touch /var/lock/subsys/local

where xactly would I add the execution of the file ? Thank you very much

After the 'touch ...' line.

[micro_sucks]

so after the touch line i would just add a
/usr/local/bin/server_start

If 'server_start' is the name of the script (which is set as executable) and '/usr/local/bin' is the directory that contains the script.
