Thanks for your replies guys Smilie

Below is a simple perl code . . Check it out . .


Code:
 
#! usr/bin/perl
use POSIX;
use strict;
use warnings;
my $file = $ARGV[0];
open FILE,'<', $file;
while (my $line = <FILE>){print $line;}
my $var = 5;
print $var;

it gave me

Code:
 
0.355u 1.00s 0:1.01 110.2% 0+0k 0+0io 0pf+0w

on the terminal, after printing the contents of the file that I've given as ARGV[0] . .
And yes, that file does not contain the above line . .

uname -a gives,
Code:
 
Linux <username> 2.6.18-274.3.1.el5 #1 SMP <date & time> x86_64 GNU/Linux

I am using Redhat 5.0 . .

Also, time sleep 10 gives,
Code:
 
0.000u 0.000s 0:10.00 0.0% 0+0k 0+0io 0pf+0w

so I guess you're on right track, Corona688

So, What does the rest four fields signify?

Thanks,
-MD

TIME(2) 						     Linux Programmer's Manual							   TIME(2)

NAME
time - get time in seconds SYNOPSIS
#include <time.h> time_t time(time_t *t); DESCRIPTION
time() returns the time as the number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC). If t is non-NULL, the return value is also stored in the memory pointed to by t. RETURN VALUE
On success, the value of time in seconds since the Epoch is returned. On error, ((time_t) -1) is returned, and errno is set appropriately. ERRORS
EFAULT t points outside your accessible address space. CONFORMING TO
SVr4, 4.3BSD, C89, C99, POSIX.1-2001. POSIX does not specify any error conditions. NOTES
POSIX.1 defines seconds since the Epoch using a formula that approximates the number of seconds between a specified time and the Epoch. This formula takes account of the facts that all years that are evenly divisible by 4 are leap years, but years that are evenly divisible by 100 are not leap years unless they are also evenly divisible by 400, in which case they are leap years. This value is not the same as the actual number of seconds between the time and the Epoch, because of leap seconds and because system clocks are not required to be syn- chronized to a standard reference. The intention is that the interpretation of seconds since the Epoch values be consistent; see POSIX.1-2008 Rationale A.4.15 for further rationale. SEE ALSO
