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

POW(3) 1 POW(3)
pow - Exponential expression
SYNOPSIS
number pow (number $base, number $exp)
DESCRIPTION
Returns $base raised to the power of $exp.
Note
In PHP 5.6 onwards, you may prefer to use the ** operator.
PARAMETERS
o $base
- The base to use
o $exp
- The exponent
RETURN VALUES
$base raised to the power of $exp. If both arguments are non-negative integers and the result can be represented as an integer, the result
will be returned with integer type, otherwise it will be returned as a float.
EXAMPLES
Example #1
Some examples of pow(3)
<?php
var_dump(pow(2, 8)); // int(256)
echo pow(-1, 20); // 1
echo pow(0, 0); // 1
echo pow(-1, 5.5); // PHP >4.0.6 NAN
echo pow(-1, 5.5); // PHP <=4.0.6 1.#IND
?>
NOTES
Note
This function will convert all input to a number, even non-scalar values, which could lead to weird results.
