You might call me ignorant, but with bash this can be done a bit simpler (this
is from my solution to the detect-if-kable-present-while-booting-problem) :-)
#!/bin/bash
while sleep 1; do
for i in /sys/class/net/eth*; do
VAR=$(basename $i)
VAL=$(sed -n 's/0/UN/p' $i/carrier)PLUGGED
if [ "${!VAR}" != "$VAL" ]; then
echo $VAR $VAL
declare $VAR=$VAL
fi
done
done
