bix.hu and www.yahoo.com are "pingable" test sites. 127.0.0.1 could not be pinged [firewall drops all icmp] i have a "oneliner" that echoes if theres "internet connection or no". $ ping -W 1 -c 2 bix.hu >& /dev/null && ping -W 1 -c 2 www.yahoo.com >& /dev/null && echo "internet connection ok" || echo "no internet connection" internet connection ok $ ping -W 1 -c 2 127.0.0.1 >& /dev/null && ping -W 1 -c 2 www.yahoo.com >& /dev/null && echo "internet connection ok" || echo "no internet connection" no internet connection $ ping -W 1 -c 2 127.0.0.1 >& /dev/null && ping -W 1 -c 2 127.0.0.1 >& /dev/null && echo "internet connection ok" || echo "no internet connection" no internet connection $ ping -W 1 -c 2 bix.hu >& /dev/null && ping -W 1 -c 2 127.0.0.1 >& /dev/null && echo "internet connection ok" || echo "no internet connection" no internet connection $ ping -W 1 -c 2 bix.hu >& /dev/null && ping -W 1 -c 2 www.yahoo.com >& /dev/null && echo "internet connection ok" || echo "no internet connection" internet connection ok $ Ok! But: if i want the "oneliner" to only go along when theres internet connection: $ while $TORF; do ping -W 1 -c 1 bix.hu >& /dev/null && ping -W 1 -c 1 www.yahoo.com >& /dev/null && TORF=false || TORF=true; done $ while $TORF; do ping -W 1 -c 1 127.0.0.1 >& /dev/null && ping -W 1 -c 1 www.yahoo.com >& /dev/null && TORF=false || TORF=true; done $ while $TORF; do ping -W 1 -c 1 127.0.0.1 >& /dev/null && ping -W 1 -c 1 127.0.0.1 >& /dev/null && TORF=false || TORF=true; done $ while $TORF; do ping -W 1 -c 1 bix.hu >& /dev/null && ping -W 1 -c 1 127.0.0.1 >& /dev/null && TORF=false || TORF=true; done $ while $TORF; do ping -W 1 -c 1 bix.hu >& /dev/null && ping -W 1 -c 1 www.yahoo.com >& /dev/null && TORF=false || TORF=true; done $ It just doesn't work. Goal: if theres no internet connection, then the oneliner must loop until there is internet connection. if theres internet connection the oneliner ends. what am i missing?
