[SOLVED] Variable Counting

[MarkTSmith78@gmail.com]

I'm also having trouble getting a variable to keep a count. Here's what I have...

function IPTest {
failCount='0'
ipTest1=`fping $1`
[[ $ipTest1 =~ alive ]] && $failCount+=1
ipTest2=`fping $1`
[[ $ipTest2 =~ alive ]] && $failCount+=1
ipTest3=`fping $1`
[[ $ipTest3 =~ alive ]] && $failCount+=1
ipTest4=`fping $1`
[[ $ipTest4 =~ alive ]] && $failCount+=1
ipTest5=`fping $1`
[[ $ipTest5 =~ alive ]] && $failCount+=1
echo $failCount
}

Now, when I run this, it properly checks the IP, but then does not add to $failCount. Instead, I get the error:

./ipMonitor: line 6: 0+=1: command not found
./ipMonitor: line 8: 0+=1: command not found
./ipMonitor: line 10: 0+=1: command not found
./ipMonitor: line 12: 0+=1: command not found
./ipMonitor: line 14: 0+=1: command not found

Help?

Thanks.

Solution found on http://tldp.org/LDP/abs/html/untyped.html.

ipTest1=`fping $1`
[[ $ipTest1 =~ unreachable ]] && let "failCount += 1"
