I am able to get the load average as u said. But i am not able to compare to a number. When i give like
FirstNumber=`uptime | sed -e 's/.*average://' -e 's/ //g' | cut -d',' -f1`
echo $FirstNumber
if [ $FirstNumber -gt 77 ]; then
echo "Greater than 77"
else
echo "Less or equal to 77"
fi
I get an error
0.34
./test2: line 3: [: 0.34: integer expression expected
Less or equal to 77
I think it needs to converted to an integer
