It would be helpful to see a sample of your converted data and the code that is trying to accumulate it. If your converted data is whole integers, then expr should work - you don't need to do any conversion on the ascii string.
If you have decimal points, expr will not handle it. You can pipe your data into the following command, which will accumulate the first word on each line, and will allow decimal points.
I am trying to display the amount of time that it took for a command to run. I'm assuming that i have the correct code:

Hi All,
I have 2 variables like SDATE and EDATE.
Now for example i ll give you values for the above 2 variables.
SDATE=11/08/09 11:22
EDATE=11/09/09 22:33
the values of the above variables are represented like this>>>>>> mm/dd/yy hh:mm Now I want to evaluate total time elapsed... (3 Replies)
I am trying to get the ellapsed time in seconds in the body of the awk script. I use unix date to get the time. It works in BEGIN {} but not in the body {} of awk. Any ideas?

Hi
I want to know if there is anyway I can find out how long it has been since I started my script or total time it has been since my script is executing.
Idea here is I want to check if my script is taking more than 30minutes to execute I want to kill that process.
Thanks in advance. (1 Reply)
I'm extracting two time & date values from a log file, and I need a way to calculate the elapsed time between the two. The values are in this format:
Feb 12 10:53:15
Feb 12 10:59:57
The difference is 6 minutes and 42 seconds
Does anyone know if there is a way to do this? I've seen lots of... (4 Replies)
Hello all,
I got some time duration data like below and I want to compute the cumulative elapsed time. The data is in MM:SS.SS format. I got struck with logic on what to do when it changes from 59:59.ss to 00:00.ss.
59:59.4
59:59.6

min
MIN(3) 1 MIN(3)min - Find lowest valueSYNOPSIS
mixed min (array $values)
DESCRIPTION
mixed min (mixed $value1, mixed $value2, [mixed $...])
If the first and only parameter is an array, min(3) returns the lowest value in that array. If at least two parameters are provided,
min(3) returns the smallest 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 min(3) returns the parameter value considered "lowest" 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 min(3)
<?php
echo min(2, 3, 1, 6, 7); // 1
echo min(array(2, 4, 5)); // 2
// 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 min(0, 'hello'); // 0
echo min('hello', 0); // hello
// Here we are comparing -1 < 0, so -1 is the lowest value
echo min('hello', -1); // -1
// With multiple arrays of different lengths, min returns the shortest
$val = min(array(2, 2, 2), array(1, 1, 1, 1)); // array(2, 2, 2)
// Multiple arrays of the same length are compared from left to right
// so in our example: 2 == 2, but 4 < 5
$val = min(array(2, 4, 8), array(2, 5, 1)); // array(2, 4, 8)
// If both an array and non-array are given, the array is never returned
// as comparisons treat arrays as greater than any other value
$val = min('string', array(2, 5, 7), 42); // string
// 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 examples, both -10 and 10 are treated as TRUE in the comparison
$val = min(-10, FALSE, 10); // FALSE
$val = min(-10, NULL, 10); // NULL
// 0, on the other hand, is treated as FALSE, so is "lower than" TRUE
$val = min(0, TRUE); // 0
