I try to use ibm_acpi on suse 9.3. After a little search, I endend up with a script ibm-acpi.sh to execute actions according to acpi events. I copied this script to the folder /usr/lib/powersave/scripts and wrote ibm-acpi.sh to the POWERSAVE_EVENT_OTHER field in /etc/sysconfig with yast2.

So the problem is that the acpi events are sent to this script but I find this error in /var/log/messages : [powersave][17426]: ERROR in Function execute_program; line 172: Came back from subprocess when trying to execute /usr/lib/powersave/scripts/ibm_acpi.sh for event other; Error: Exec format error

my script is :


#!/bin/bash
# ibm_acpi.sh
# Frank Fiene
# Based on the scripts of Manfred Tremmel and Stefan Seyfried
#

echo "ibm_acpi $*"| \
logger

Eitherway if I wirte only one line to this file instead of all this stuff it gives the same error...

any help??
