As dev is no longer used anywhere else from now on, the section getting it could be cleaned-up as well with the exception of the dummy variable:
# first get first active network device local dev dummy n n=0 until [ $n = 7 ]; do dev=$(ip ad show up | awk -F': ' '/^[0-9]/ && ! / lo:/ {print $2;exit}') if [ -z "$dev" ]; then sleep 2 # if interface needs some time to come up else break fi n=$(($n + 1)) done Thanks again for your fast response.
