I just wrote a little script, that will echo a message to the user, if it doesn't have enough permission:
$ if ! [ "$(env LC_MESSAGES=C ifconfig wlan0 down | grep -i denied)" == "" ]; then echo "no permission"; fi
SIOCSIFFLAGS: Permission denied
$ sudo su
[sudo] password for USER:
# if ! [ "$(env LC_MESSAGES=C ifconfig wlan0 down | grep -i denied)" == "" ]; then echo "no permission"; fi
#
but it won't works
why?
