This works fine as long as i run the script from shell. If I start the script using runlevel during startup the script runs but the variables are empty.
All interaces are up at this time so there must be another reason why /sbin/ifconfig returs no value. Could someone please help me?
Is at startup only a limited shell available? (I mean ash, dash, nash, etc, etc and not BaSH.)
Does the script run with root rights?
What shows if you run the script but only save the output to a file for troubleshooting purposes? Is it still empty?
BTW why run ifconfig four times when you can output to a temporary file once and grep that four times?
Thanks for the reply.
Yes indeed, this could be shortend to execute ifconfig just one time...

Well I think bash is availible because the scripts is running in the background and acting as it should. It checks incomming SMS from a huawei UMTS stick.
Once it gets the SMS, it checks for command, executes and sends back a sms. Everything is working fine except the output varibles ETH0, WLAN0... are empty. It is running as root because reboot command per SMS etc. work fine.
BTW
Code:
FILES=`ls -A /home/inbox/*${SMSNUMMER}* 2> /dev/null`
