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

LEARN ABOUT DEBIAN

vendorlib

vendorlib(3pm)						User Contributed Perl Documentation					    vendorlib(3pm)

NAME

       vendorlib - Use Only Core and Vendor Libraries in @INC

SYNOPSIS

	   #!/usr/bin/perl

	   use vendorlib;
	   use strict;
	   use warnings;
	   use SomeModule; # will only search in core and vendor paths
	   ...

DESCRIPTION

       In a system distribution such as Debian, it may be advisable for Perl programs to ignore the user's CPAN-installed modules and only use the
       distribution-provided modules to avoid possible breakage with newer and unpackaged versions of modules.

       To that end, this pragma will replace your @INC with only the core and vendor @INC paths, ignoring site_perl and $ENV{PERL5LIB} entirely.

       It is recommended that you put "use vendorlib;" as the first statement in your program, before even "use strict;" and "use warnings;".

BUGS

       Please report any bugs or feature requests to "bug-vendorlib at rt.cpan.org", or through the web interface at
       <http://rt.cpan.org/NoAuth/ReportBug.html?Queue=vendorlib>.  I will be notified, and then you'll automatically be notified of progress on
       your bug as I make changes.

SUPPORT

       You can find documentation for this module with the perldoc command.

	   perldoc vendorlib
