GAH bootscripts.

[mcdougrs]

I have no idea... It was in the original and I just put in what I thought would be right.

Oh and byt the way what did this part do;

>/dev/null 2>&1

I know that it sent it to /dev/null but what is that 2>&1 business?

[mcdougrs]

Well I was wondering if someone might be able to help me fix this error message when I start up FAH from the script above I get this:

[root@thalia init.d]# /sbin/service folding start
Starting Folding@Home client ... /etc/init.d/folding: line 11: evaluate_retval: command not found

I assume that it is a problem with the /etc/init.d/functions part toward the top of the script but not certain.

You can remove that line from teh script if you want to, all it does is see if it went well, and print the [OK] or [FAILED] according to it.

Since you already use:
source /etc/init.d/functions
I would guess this would have the same effect:

#!/bin/sh
source /etc/init.d/functions
FAH="/home/mcdours/fah/FAH3Console-Linux.exe"
cd /home/mcdours/fah/ >/dev/null 2>&1
RETVAL=1
case "$1" in
        start)
                echo -n "Starting Folding@Home client ... "
                su mcdours -c "$FAH >/dev/null 2>&1 &"
                RETVAL=$?
                ;;
        stop)
                echo -n "Stopping Folding@Home's FAH3Console-Linux.exe ..."
                killproc FAH3Console-Linux.exe
                RETVAL=$?
                ;;
        restart)
                $0 stop
                /usr/bin/sleep 1
                $0 start
                 RETVAL=$?
                ;;
        status)
                statusproc FAH3Console-Linux.exe
                 RETVAL=$?
                ;;
        *)
                echo "Usage: $0 {start|stop|restart|status}"
                exit 1
                ;;
esac
exit $RETVAL

Hmm... just thought, if you get into trouble with the killproc and status_proc functions aswell.. here is the way I would make the script..

#!/bin/sh
source /etc/init.d/functions
FAH="/home/mcdours/fah/FAH3Console-Linux.exe"
cd /home/mcdours/fah/ >/dev/null 2>&1
MY_USER=mcdours
RETVAL=1
case "$1" in
        start)
                echo -n "Starting Folding@Home client ... "
                TMP=`su $MY_USER -c "$FAH >/dev/null 2>&1 &"`
                echo $TMP | awk '{print $2}' >! /var/run/$MY_USER-FAH.pid
                RETVAL=$?
                ;;
        stop)
                echo -n "Stopping Folding@Home's FAH3Console-Linux.exe ..."
                kill `cat /var/run/$MY_USER-FAH.pid`
                RETVAL=$?
                ;;
        restart)
                $0 stop
                /usr/bin/sleep 1
                $0 start
                RETVAL=$?
                ;;
        status)
                echo -n "Pid of running FAH: "
                cat /var/run/$MY_USER-FAH.pid
                RETVAL=$?
                ;;
        *)
                echo "Usage: $0 {start|stop|restart|status}"
                ;;
esac
exit $RETVAL

Thanx man I used your fisrt script as the second one gave me troubles... I do want to change one thing though... I want to forward it to tty12 so I can actually keep an eye on it, BUT I get a permission denied error for the startup for this:

        start)
                echo -n "Starting Folding@Home client ... "
                su mcdougrs -c "$FAH >/dev/tty12 &"
                RETVAL=$?
                ;;

Can I safely change the permissions on tty12 or is there someway I can forward the output of FAH to some sort of terminal? I would REALLY like to be able to keep an eye on FAHs output, if its possible

[redhead]

You could either change the permission on /dev/tty12, or add your user to the tty group ie:
> usermod -G tty mcdougrs

Either way the user will be allowed to write to /dev/tty12, when adding your user to the tty group, you will assure that it can write to any tty, not just the one where the permissions has been change.

Awesome THANX!!!

OOOOOOOOOOOOOOPPPPPPPPPPPPPSSSSSSSSSS!!!!!!! I figured out what that second & does in the script! : It returns the prompt to the computer.. right now it just freezes waiting for FAH to finish... I need to get in and re-edit the script... I made a boot disk at RH8.0 install time but how do I boot up so that I can JUST edit that script?

[redhead]

boot into runlevel 1.
If you use lilo as the bootmanager, then at the LILO: prompt, type 'linux single' (without the quotes) then you're droped into a root shell, without any of the normal processes beeing started.
Then when you're finished editing the script, just use: 'telinit 5' (if its runlevel 5 you're used to boot into)

I use grub, but I figured out how to get into my system with out using the boot disk.... I just entered Interactive Startup and I didn't start the folding script! It was that easy then I went in and edited it and wholla here I am!

Thanx for all the help and thanx for posting that revised script for me!
