[SOLVED] Bash shell script that will count the output of df -h.

Hello all, I am working on a script but I am having a problem figuring out how to accomplish my task. I am stuck at the if statement, here is what I am doing. I want to be notified if the count is less than 6. I know the "$?" is wrong but as it is looking at the exit code. I dont know what I should put there. Any help would be great thanks.

Code:

/bin/df -h
if [ $? -lt 6]; then 
 "send email."
elif "echo something"
fi

if you are just trying to count the number of lines in the output of df -h this works for me:

Code:

#!/bin/bash
value=$(/bin/df -h|wc -l)
if [ $value -lt 6 ]  
then  
        echo "something."  
fi
