"date2 - date1": elapsed time in hrs, mins, and secs

How to calculate the elapsed time in hrs, mins, and secs:

For example, in the script, it has

d1=`date`
......
d2=`date`

How to get the time difference between d2 and d1.

Thanks.

Perl's Date::Calc module is ideal for this task.

You have multiple options here:

perl:  
$start_time = time();
<Your Script Here>
$end_time  = time();
$time_taken =  $start_time - $end_time;

Or use some CPAN module: benchmark, Date::Calc, etc.

*nix Shell Cmd Line:
prompt> time <Your Script Here>

I am not aware which shell you are working in. Otherwise I could have suggested
a shell specific calculation.

Use of perl will make it Shell and OS independent, which is a good thing in long run.
