[Gllug] Simple Bash Script

[william pink]

Well I have made the suggested adjustments but it still doesn't appear to
work

#!/bin/bash

# Script for debbie to check system load and remove from cluster if higher
than 8.0

TEMPFILE="$(mktemp)"
NOTIFY="3"
HOST=`hostname`
#RCLUSTER=`/usr/local/bin/in-cluster no`
#load at 1 minute
TRUE="1"
LOADAVG=$(cut -f1 -d' ' /proc/loadavg)

#input in tempfile
echo "Load average to high removed from cluster, Load currently at $LOAD
allowed limit $NOTIFY." > $TEMPFILE

# Compare results to benchmark
RESULT=$(echo "$LOADAVG >= $NOTIFY" | bc)

# IF so do your thing

if [ "$RESULT -eq $TRUE" ]; then
    echo "test failed!"
    else echo "No problem to report"
fi

rm -f $TEMPFILE

Does the last if statement look correct?

Thanks,
Will
