Parsing the output from top

Guys can you help me fix this parse error.

Here's my script.

Code:

#!/bin/bash
# Set up limit below

NOTIFY="6.0% us 6.1% us 6.2% us 6.3% us 6.5% us 6.6% us 6.7% us 6.8% us 6.9% us 7.0% us"

# CPU Usage every minute
TOP="$(top -b -n2 -d 00.20 |grep Cpu|tail -1 | awk -F ":" '{ print $2 }' | cut -d, -f1)"

# compare it with last usage
RESULT=$(echo "$TOP > $NOTIFY" | bc)

# if load >= 80.0% create a file /home/scripts/loadavg.txt

if [ "$RESULT" = "6.0% us 6.1% us 6.2% us 6.3% us 6.5% us 6.6% us 6.7% us 6.8% us 6.9% us 7.0% us" ]; then
        echo $RESULT "cpu usage" >>  /home/scripts/loadavg.txt

This will output the cpu usage then compare on the notify now i'm getting this error

Code:

-bash-3.00$ sh -x cpu 
+ NOTIFY='6.0% us 6.1% us 6.2% us 6.3% us 6.5% us 6.6% us 6.7% us 6.8% us 6.9% us 7.0% us'
++ top -b -n2 -d 00.20
++ grep Cpu
++ tail -1
++ awk -F : '{ print $2 }'
++ cut -d, -f1
+ TOP='  6.7% us'
++ echo '  6.7% us > 6.0% us 6.1% us 6.2% us 6.3% us 6.5% us 6.6% us 6.7% us 6.8% us 6.9% us 7.0% us'
++ bc

Thanks in advance.

ovs-parse-leaks

ovs-parse-leaks(8)						Open vSwitch Manual						ovs-parse-leaks(8)

NAME

       ovs-parse-leaks - parses OVS leak checker log files

SYNOPSIS

       ovs-parse-leaks [binary] < log

DESCRIPTION

       Many  Open  vSwitch  daemons  accept a --check-leaks option that writes information about memory allocation and deallocation to a log file.
       ovs-parse-leaks parses log files produced by this option and prints a summary of the results.  The most interesting part of the output is a
       list of memory blocks that were allocated but not freed, which Open vSwitch developers can use to find and fix memory leaks.

       The  log  file must be supplied on standard input.  The binary that produced the output should be supplied as the sole non-option argument.
       For best results, the binary should have debug symbols.

OPTIONS

       --help Prints a usage message and exits.

BUGS

       The output can be hard to interpret, especially for a daemon that does not exit in normal operation.  Using  ovs-appctl(8)  to  invoke  the
       exit command that some Open vSwitch daemons support sometimes helps with this.

       ovs-parse-leaks	usually  incorrectly  reports one or more ``bad frees of not-allocated address'' errors at the beginning of output.  These
       reflect frees of data that were allocated before the leak checker was turned on during program initialization.
