dbar - ASCII progresbar SYNOPSIS
echo <percentage> | dbar [options] <indicator text> DESCRIPTION
dbar lets you define static 0% and 100% marks or you can define these marks dynamically at runtime. Static and dynamic marks can be mixed, in this case the value specified at runtime will have a higher priority. You can specify ranges of numbers, negative, positive or ranges with a negative min value and positive max value. All numbers are treated as double precision floating point, i.e. the input is NOT limited to integers. OPTIONS
-l Label to be prepended to the bar (default: "" ). -nonl no new line, don't put ' ' at the end of the bar (default: do print " ") -max Value to be considered 100% (default: 100). -min Value to be considered 0% (default: 0). -s Symbol represeting the percentage value in the meter (default: "="). -w Number of charcaters to be considered 100% in the meter (default: 25) EXAMPLES
Static 100% mark or single value input: echo 25 | dbar -max 100 -l text Output: text 25% [====== ] If your 100% mark changes dynamically or 2-values input: echo "50 150" | dbar | | | |__ max value | |__ value to display Output: 33% [======== ] If your value range is not between [0, maxval] or 3-values input: echo "50 -25 150" | dbar | | | | | |__ max value 100% mark | | | |_____ min value 0% mark | |________ value to display Output: 43% [=========== ] Multiple runs: for i in 2 20 50 75 80; do echo $i; sleep 1; done | dbar | dzen2 Output: Find out yourself.

MAX(3)									 1								    MAX(3)

max - Find highest value

mixed max (array $values) DESCRIPTION
mixed max (mixed $value1, mixed $value2, [mixed $...]) If the first and only parameter is an array, max(3) returns the highest value in that array. If at least two parameters are provided, max(3) returns the biggest of these values. Note Values of different types will be compared using the standard comparison rules. For instance, a non-numeric string will be com- pared to an integer as though it were 0, but multiple string values will be compared alphanumerically. The actual value returned will be of the original type with no conversion applied. PARAMETERS
o $values - An array containing the values. o $value1 - Any comparable value. o $value2 - Any comparable value. o $... - Any comparable value. RETURN VALUES
max(3) returns the parameter value considered "highest" according to standard comparisons. If multiple values of different types evaluate as equal (e.g. 0 and 'abc') the first provided to the function will be returned. EXAMPLES
Example #1 Example uses of max(3) <?php echo max(2, 3, 1, 6, 7); // 7 echo max(array(2, 4, 5)); // 5 // The string 'hello' when compared to an int is treated as 0 // Since the two values are equal, the order they are provided determines the result echo max(0, 'hello'); // 0 echo max('hello', 0); // hello // Here we are comparing -1 < 0, so 'hello' is the highest value echo max('hello', -1); // hello // With multiple arrays of different lengths, max returns the longest $val = max(array(2, 2, 2), array(1, 1, 1, 1)); // array(1, 1, 1, 1) // Multiple arrays of the same length are compared from left to right // so in our example: 2 == 2, but 5 > 4 $val = max(array(2, 4, 8), array(2, 5, 1)); // array(2, 5, 1) // If both an array and non-array are given, the array will be returned // as comparisons treat arrays as greater than any other value $val = max('string', array(2, 5, 7), 42); // array(2, 5, 7) // If one argument is NULL or a boolean, it will be compared against // other values using the rule FALSE < TRUE regardless of the other types involved // In the below example, -10 is treated as TRUE in the comparison $val = max(-10, FALSE); // -10 // 0, on the other hand, is treated as FALSE, so is "lower than" TRUE $val = max(0, TRUE); // TRUE ?> SEE ALSO
