This works Firstly, If you structure your code a little more, then you will be able to see where things aren't quite right. My example should give you the idea of indenting your code blocks. My example, provides you with a simple IP address check. I am not sure if this is what you want, but it does work. The script could be optimised, but I have made it simple for you to see exactly whats going on. Code: #!/bin/bash IPADDRESS='192.168.1.1' PROXY=`ping $IPADDRESS -c 1` PROXY1=`ping $IPADDRESS -c 1 | grep 1\ received` echo "$PROXY" echo "$PROXY1" if [ "$PROXY" ]; then if [ "$PROXY1" ]; then echo "OK" else echo "gnet down" | sendmail -t [email protected] echo "gnet down" fi fi Hope this helps.
